Bug Description
I'm running up-to-date intrepid. I have a volume control wheel on the side of my Toshiba U300 laptop. This volume control did work as expected in hardy. It operates like a scroll wheel on a mouse, in the way that it has specific points at which it sends a signal. When I got to these points on hardy, the volume would just increase or decrease by one block.
With intrepid it gets the volume to go up one block, then waits for a second and then keep turning the volume up constantly without stopping. I've found if I hold a key on the keyboard down, for example Ctrl, it stops it temporarily. When I release Ctrl it start zooming off increasing or decreasing again. I have found if I swap desktops by holding down Ctrl Alt Left or Right, it stops it zooming off increasing or decreasing completely.
I'm sorry if the above was a bit confusing. It's surprisingly hard to explain :)

First, gnome-audio has nothing to do with your problem. gnome-audio is a package
with a bunch of audio files to be played when certain events occur, ie. an audio
theme.
As for using the dial "breaking the keyboard handling", I'm not quite sure what
it means. You could try using the dial on the command-line instead, with a tool
like evtest (not packaged, look for evtest.c on google), or printing whatever
xev gives you back (even if you need to switch VTs to get to the result).
My guess is that this Toshiba laptop needs a driver to make this button work
appropriately. Reassigning to the kernel, where hopefully somebody will have the
hardware to test this, and point the finger back at GNOME if it's indeed the
culprit (unlikely).

This is not a kernel problem.
This volume dial sends normal multimedia keyboard VolumeUp and VolumeDown
keypresses. But I guess with some additional keycodes. In GNOME Keyboard
Shortcuts these are correctly identified as XF86AudioRaiseV
XF86AudioLowerV
Under textmode console there is no problem. Turning the volume wheel yelds some
~ characters on screen only, but the keyboard is still working.
Under XOrg, once I move the volume dial, keyboard is not working anymore. Maybe
it is switched to RAW mode or something? (I don't know the exact X internals).
So, this is more likely XOrg/GNOME problem, not kernel.
I would gladly help debugging it, but I do need some guidance.

click, let showkey terminate and post the output?

can you run evtest [1] on the device file and move the wheel by one? this should
indicate whether a key down event is being sent.

I don't like that patch because it breaks auto-repeat for a huge number of
perfectly working keyboards, and it adds policy to the X server. This should
probably only be done if a certain hal property was present.

yep, same problem. we never get a key up event, resulting in endless key repeats

agreed. mjg59 was talking about a kernel quirk for this, this is the "correct"

After pressing the buttons some more I can get the OSD to disappear, but now none of the GNOME menus will drop down (they do highlight though). I got out of this by pressing my power button and selecting reboot from the pop-up options.

I'm running Intrepid vanilla 32bit on a Hewlett Packard zv6511ea and when I use the volume +/- keys I lose keyboard and mouse functionality in the same way as described above. That is: I can highlight menu names, like Applications, Places, System but am unable to select or expand the menus, and they keyboard keypresses do not appear in a Gnome terminal menu. And pressing Ctl-Alt f1 to switch to a virtual terminal, then Ctl-Alt f7 to switch back to X, I regain control. Also one press of the volume down hotkey will reduce the volume to 0. You can see the on-screen display reduce from the current level down to zero.
This sounds very like bug #285323, but what would I know.

Why don't we implement the same solution that was implemented in the old Xorg KBD drivers?
That is, add to the PostKbdEvent() function in evdev.c something along the lines of:
/* fix events for volume keys */
if(ev->code == KEY_VOLUMEDOWN || ev->code == KEY_VOLUMEUP)
{
//post a keydown and then a keyup, as media keys have no automatic key-up

ktemkin (kyle-ktemkin) wrote : | #33 |
@Taner Senyurt:
I'd like to point out:
1) This isn't a problem with Jaunty, nor Intrepid. Instead, it's a problem with the "evdev" driver. The reason these problems are showing up in these distributions is that they use the newer "evdev" driver instead of the older "kbd" driver.
2) The link you posted to your blog/solution is actually pretty much a transpose of my earlier "temp fix", located at http://
than a temporary fix; it's very user-specific and requires attention any time there is an evdev update.
The problem still exists in Jaunty's evdev because the developers aren't quite sure where to fix it. Different models of computer behave differently given the volume keys. Most of these problem laptops 'hang' because they never send a key-up event; other computers (the majority) do. If one modifies the driver the way I have in the post I've written above, it's at the price of other users having a different problem: they press and hold their volume up key, and the volume only increments once.
The real solution needs to be implemented in a way that doesn't negatively affect the majority for the sake of providing functionality to the minority. For now, the minority can use this 'temp fix', while the developers decide where exactly to implement this 'fix' functionality. Perhaps later, there will be a more conclusive solution.

I can confirm this issue, and I have a lot more information for whoever is pursuing this.
(I originally posted this in the following thread)
http://
This issue is not ubuntu-specific - I have witnessed this in gentoo too (and likely affects them all, based on this bug). (Bear with me)
I originally tried mapping the volume up/down keys to multimedia functions within gnome using XModMap within gentoo (basically creating aliases for special commands within Xorg), but then found the very same problem in gentoo - so I pulled off the keymaps and took a look for what was happening on keyboard input.
Fortunately, I was able to test a few more things within gentoo - but I can confirm that this issue is guaranteed to be from the same source as the problem within ubuntu.
I tried using xev, a program for watching input via event-based devices within xorg, and noticed that pressing either of the volume up/down keys on the R4125CA (R4000-series compaq laptop) causes one key signal while a volume up/down button is pressed, and the moment either of those is released, a completely different signal from the first is spammed endlessly - no other keypresses will stop this.
So, I tried using "showkey" from outside of Xorg, in a framebuffer console (basically command-line without gui ) . Interesting, pressing and holding a volume up creates two seperate scan codes - something that I would imagine to be EXTREMELY quirky (and a terrible hack?). I am not aware of any software for linux that will correctly interpret a double scan code. But I suggest that the developers for ubuntu might be able to file this information with whomever would be responsible for dealing with this.
Also important, this bug is present __with or without__ xf86-input-evdev ==> meaning that the problem has to start even before the keypresses are getting to Xorg's evdev driver. Perhaps in the kernel source for evdev ? *tear* :(
My locale and console region when dealing with this were EN-US and UTF-8.
As for the above issues of having the mouse pointer clicks not occuring - what I think I noticed was that following a volume key (for this device), a mouse click's signal is different, which explains why none of the mouse clicks after this event were working. (Don't take my word for it, I was watching the input scroll very fast - and can post a log if we need to confirm this)
I would also like to point out that physically inside this system, it appears that the multimedia buttons are not directly part of the physical keyboard, though they might get combined via hardware later on (Which could be the real source of this mess - and software would be how windows *ahem* is dealing with this issue)
I can also confirm that this issue exists on the livecd.
Just as a suggestion: I believe it was the ZV-6000 (i think compaq) has similar internals to the R4000 - perhaps this issue should contain this information as well for whomever is trying to test it.
If ubuntu needs more debugging information, I will be happy to test this further, since I'm quite interested in fixing this for everyone -- because this issue has been present for a LONG time i...

I don't think you're correct at all in diagnosing that the problem _isn't_ evdev. Making a few code modifications to the evdev driver to account for the odd scancode reporting fixes it right up, even if the volume control isn't as smooth as the windows version is. This definitely indicates that the problem is (at least resolvable) in evdev.
I think I'm repeating myself, but I'll explain basically how the scancode works on a normal keyboard key:
1) The keyboard (hardware) reports a scan-code indicating that the key has gone _down_. This indicates which physical key was pressed to the software.
2) The 'driver' software translates the scan-code to the correct key-press in the system locale and reports it to the shell/x-server/etc as a 'key event'.
3) The driver code waits a specific amount of time for another scan-code, indicating that the key has gone _up_. When this is not received, it sends another key 'event'.
4) Finally, the key is released, and the keyboard reports a scan-code indicating that they key has gone _up_. The driver stops paying attention, as it knows no (further) auto-repeat is required.
The problem is that when keyboards with media keys were first created, there wasn't an explicit media keys standard- many OEMs provided their own drivers. These keyboards, as often as not, did not bother to send key-up events for their media keys. After all, keys like "stop", "eject", "play', and etc. didn't really necessitate knowing when the key was released, only when it was pressed.
When the media key format became more standardized, both the windows drivers and the original X 'kbd' driver made a modification to their code, which automatically injected a key-up directly after a key-down for any media key. This 'hack' essentially turned of auto-repeat for media keys.
Up until Hardy Heron, Ubuntu utilized the older X 'kbd' driver- so you may notice that your volume keys work fine there. However, in the newer versions, the 'evdev' driver is utilized instead, which lacks the fundamental media-key-norepeat hack.
When I have time, I'll work on a similar hack for evdev- I have a prototype running on my machine (and several other users machines) that works perfectly, but I haven't had time to smooth out a few things (like the fact that this makes the volume 'keys' extremely oversensitive on the volume wheels of the U300 series.)

@ktemkin :
I understand that position entirely, but I was under the impression that evdev events originate within the kernel itself, and that they get sent at probed intervals as long as a key is considered "down" by the hardware.
After reading more source code, it looks like it is actually event-based, in that a "down" or an "up" is sent, ONLY once, by the kernel, and that the evdev (or kbd, as i also found in one of my test cases -- which also has the problem for the r4000/zv6000), is what generates the repetition.
Yummy... answers, time to play with patches :)

@ktemkin:
Okay, got something you might enjoy besides more confusion:
Just writing
+ if(ev->code == KEY_VOLUMEDOWN || ev->code == KEY_VOLUMEUP)
+ return;
Unfortunately seems to result in no keyevents for the volume up/down buttons at all (R4000) , as indicated by xev.
I think you original modification was more correct with this:
if(ev->code == KEY_VOLUMEDOWN || ev->code == KEY_VOLUMEUP)
{
//post a keydown and then a keyup, as media keys have no automatic key-up
xf86PostKeyboa
xf86PostKeyboa
return;
}
Also, I suggest a slightly improved version of this, because this modification will apply for all xf86-input-evdev generated events (so for people whom have two keyboards with volume buttons, one working, one quirky, we would be throwing volume "up then down" events (as per above), for keyboards that successfully have the "volume key release" event correctly implemented. To fix such, I suggest the following:
+ if (ev->code == KEY_VOLUMEDOWN || ev->code == KEY_VOLUMEUP) {
+ if (value) {
+ xf86PostKeyboar
+ xf86PostKeyboar
+ }
+ return;
+ }
+
^ ^ if my understanding of "value" is correct, one that evaluates to true should mean a "keydown" event -- this way, a working keyboard that correctly implements "volume key release" will not generate an extra "up then down" when we release a volume key on a working keyboard (and yes, some of us use 2, if not 3 keyboards xD)
Keep in mind that although this DOES stop the auto-repeat symptoms for our events within the xf86-input-evdev driver (as you said earlier). I'm not convinced that this is the source of the problem, and would thus classify this as a "hack-fix" to relieve symptoms. (see my next comment)

- Log of showkey -s, compaq R4125ca Edit (501 bytes, text/plain)
Within a framebuffer console, no xdm started:
Output from showkey, which parses kernel output from /dev/console , is not based on kernel evdev driver. (So, way before evdev which normally provides events to xf86-input-evdev).
Normally, output from showkey would look like this for regular keys:
"f"
keycode 33 press
keycode 33 release
"k"
keycode 37 press
keycode 37 release
"j"
keycode 36 press
keycode 36 release
Notice that the attached output from "volume down (press x2, then press/hold for 5 seconds), then repeat for volume up" doesn't generate additional "release" events. This seems to be outside of the scope of evdev.
The information is in agreement that our hardware isn't getting the right "release" events to the kernel -- most likely because a release event is not implemented at the hardware level.
In the interest of kernel efficiency, if we were to start running checks in the kernel input driver itself (way out of my league here, but just theoretically), for "if it's a volume key", the additional check would get applied for every key - but that's something we're already doing -- except after a series of calls have made their way to xf86-input-evdev. It almost makes finding a way to generate a "release" event earlier, somewhere in the kernel, justified.
Nonetheless, let me know if you agree with the fix to your patch posted in the above comment -- handling this within input-evdev isn't entirely proper, and may add 1 or two extra non-intensive function calls, but it makes for an easy fix :)

Actually, I've found the former works better with the U300 series (as mentioned in the bug itself; the U300 toshibas have an odd volume wheel which loses sensitivity with the latter fix), while the latter is a more general-case solution.
As per the source of the problem, I've spoken with some people familiar with the history of evdev/kbd, and the consensus is that we're trying to fix a hardware problem with software. While that's generally not the best approach, we're left little choice.
After a lot of thought, the consensus on the kbd project was to use a hack similar to mine. It is very much a hack- but I don't know what else we can do.
If anyone has any better suggestions, I'd be glad to listen. I expect I'll get more work done on this tomorrow; I plan on borrowing another laptop (I have a U305) that exhibits this problem so I can do some more keyevent testing.

Hmm, this is just a random thought, but perhaps you might be able to write a hacked version of xf86-input-evdev based on the "value" returned by the volume key events (it seems the kernel knows something we don't? :D ). I noticed that for the R4000, the volume keys do not generate value = 0 OR value = 1... they ONLY generate value = 2 for volume keys (when i compare it to other key events, i believe it means that the key is being held "down").
Is it possible that this is the same for the U300 ? If it is... then we may have a means of identifying these "problem" keyboards within evdev - compliant drivers.
You should test the other quirky machines, for their reported "values" with sudo evtest /dev/input/eventX (keyboard) -- to see if they too only create value = 2 events for volume "keys" -- just a thought for a generic solution :)
I'm not sure if these "value" outputs from evtest are the same values seen within the source of input-evdev... but if these problem machines have a lot in common, we may have a way of disabling auto-repeat similar to your hack.

@ Tomasz Sterna : an excellent find. I followed the changes along the kernel cvs, and it looks like a proper fix for the R4000/zv6000 would be very similar to the bugs that were fixed in that report, via the kernel input drivers.
(We may need more information for the U300, particularily, an evtest dump of the volume dial in action.)
Specifically, these links look extremely like what we should be aiming for in any stuck keys:
Take a look at the original bug report, and the event output generated by the kernel (fedora, yes it's a Zepto 6615WD, but bear with it):
https:/
Notice the events reported are the exact same as for the R4000/ZV6000, even the event codes:
0xe0 0x2e
0xe0 0x30
Now look at the fix (for the Zeptec) within the fedora kernel... handled within /drivers/
http://
I'm very tempted to play with this myself once i get a free moment.
I understand this bug has gotten plastered with zv6000/R4000 non-wheel (although related) problems, so it would be good to get the focus back to the original U300 system.
Can anybody post an evtest for the U300?

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:

Andrew Gee: Can you run the following?
(Before you do this, make sure if you're in X/KDE/Gnome that you save and close your work, as you already mentioned that trying the volume wheel while in there may distort some of your input devices).
# echo "dmidecode > mydmilog.txt" | sudo bash
(will help us identify your laptop series in the quirk, if we get that far)
# echo "showkey -s > mykeylog.txt" | sudo bash
(For more complete information on the wheel... some of the information provided was slightly inconclusive)
Then move the wheel a single position up, followed by a single position down, and then a single up, and then a single down (try to be precise for these first ones) -- and then move it up several clicks, and then down several clicks? That program will stop logging after 10 seconds of inactivity, and will end automatically.
---
I find it strange that there is a 0,1,0,1,0,1 (total 6) in your volume up, and only a 1,0,1,0,1 (total 5) in your volume down -- also, that the volume down started at '1', vs volume up at '0'.
(To Debuggers reading this: if this is true, just a thought, the physical wheel might be a little imprecise in the scancodes that it transmits ... Getting an up-down-up-down "randomness" might generate more complete logs to try to get to the bottom of this - and i think it would really help to know exactly what and how many, or if there is some kind of variance or imprecision in the sensor - at which point we can decide what we can safely assume for the kernel quirk)
Thank you for the info thus far =D

If anybody is subscribed to this bug and does not own a U300, please search for a volume repeat/stuck problem related to your hardware, to keep things organized for the maintainers. Unfortunately we have to deal with these keyboard quirks on a hardware-
As far as a patch goes for the U300, I will see about writing one for this system, based on the above information. I'm not sure if what I have in mind will work, but I will try to write a patch for the U300 for on the current Ubuntu kernel - and then hopefully someone in this bug subscription is comfortable/capable of compiling an ubuntu kernel to test it on a U300.
(Although I must say, this one is the most unique keyboard hardware quirk I have seen yet).
To illustrate this hardware quirk, for those trying to understand it (or those curious =D):
Wheel Up = on, off, on, off, ON (so keep sending from this point on)
Wheel Down = on, off, on, off, ON (so keep sending from this point on)
But when we do it again:
Wheel Up = negate last "up" state (so OFF), on, off, on, off
Wheel Down = negate last "down" state (so OFF), on, off, on, off
cycle complete.
I will do my best in the absence of any accountable logic on your part, Toshiba xD

I think I can almost see their design rationale, especially if they wanted the controlling logic to be compatible with more than just their volume wheel- but deviations from any standard are almost always more headache than they're worth for developers, especially when documentation isn't available.
@jetdog:
My U305 has a compatible keyboard module, I can compile and test any kernels you provide.
Looking at various source versions of the old 'kbd' drivers, I'm of the opinion that it might be best to also hack a fix in input_evdev. It doesn't exactly address the source of the problem, but quirking the kernel for all of the keyboard configurations that suffer this issues will be a long and arduous process, especially considering all the testing and scrutiny a change has to be placed under before it can make it upstream.
Wouldn't it be better to, in addition to quirking the kernel, provide a hack in evdev with a single additional non-intensive call that would provide more immediate relief to the users? This is what was done in the 'kbd' drivers, though those used a different method of determining key events.

To all developper's attempting to fix this bug:
This problem exists in the __kernel__. Not in evdev. Not in X. Not in Gnome, KDE, or anywhere else.
Quirking the evdev driver does not fix this problem - and your evdev driver AND the kernel will probably be faced with increased CPU time as a result of key-event message passing. What happens is that once the kernel starts spamming the volume up/down key signals to the various kernel/X input handlers (i.e. anything that begins with xf86-input-____), X gets spammed with key events, causing the lockups you're describing.
The reason the kernel spams evdev is quite simple: We have logs earlier in this thread that indicate that the physical hardware implementing the PS/2 protocol on the keyboard do not create a release event for the volume buttons (this wheel produces "down" ticks, but __does_not_always__ produce "up" ticks).
Quirking evdev, as per the solution by ktemkin described in this thread, and on a repeatedly referenced ubuntuforums post, will __not__ stop this increased key-event message passing! It will only cause evdev to ignore the respective key signals from the kernel, but it is an extremely hackish-fix,and your kernel input handling will still be highly clogged! Also, the problem will reoccur if you (or ubuntu official) were ever to switch away from using xf86-input-evdev.
The problem starts WAY earlier than evdev. It (likely) exists in the input/drivers/
We need to get some kernel bugfixers in here! I would fix this myself, but real-life work is unfortunately taking the majority of my time.
I hope this will jumpstart a fix -- i know it's rough trying to find someone to get this stuff done!

I might be able to find time to write a kernel quirk over the holidays; currently I'm up to my eyebrows in work.
Similar quirks exist for other machines already, see this link for a sample:
https:/
If everyone subscribed and still experiencing this problem could post their DMI_SYS_VENDOR and DMI_PRODUCT_NAME, it'd be helpful.
The patch I offered above for evdev is designed to mask your symptoms; which is useful during the wait- but a better option still would be to, in conjunction, remap the volume up/down keys to another keyboard combo and avoid touching the wheel. Avoiding those keys altogether will minimize the spurious CPU usage until a quirk is done.
Again, my 'fix' is pretty much a crude hack for evdev that filters out the additional events at the X-input level. It will not fix the underlying problem- the kernel.
Good luck, and if anyone wants to try their hand at quirking the kernel, I'm sure you'd have plenty of ready testers. If not, hopefully I'll get to it before too long.

"Where do I find DMI_SYS_VENDOR and DMI_PRODUCT_NAME?"
Those are part of the Microsoft DMI information, provided by the physical hardware. There is no giant list of which one gets what DMI -- so we just test a few and see if our findings are consistent. It is used for identifying hardware to kernels and software.
(That DMI flag and your scancodes is about all you need to quirk atkbd... and a tiny bit of C =D)

jetdog: there is an open bug in the kernel tracker, maybe it just need a bit of data from people more expert than me. I added the upstream bug, hope I did not do anything wrong.
mrvanes: I have a command "dmidecode" for this. I think the requested data is this one:
(0)rukbat:~% sudo dmidecode | grep -i vendor
Vendor: TOSHIBA
(0)rukbat:~% sudo dmidecode | grep -i product

The DMI information gathering is good. Whoever is making a patch will need the whole array of U300 DMI_PRODUCT_NAME (s).
As we've already seen, a U305 has come up. I did some light research and it seems that only the U300 and U305 are in this series.
If anybody has anything in the U300-series that is not a 300/305, please reply so that we can target your DMI info in the patch.

I am assigning this bug to myself, since I am working on a patch for this bug. From what I can gather, all models of the U305 series have the same DMI_PRODUCT_NAME, same with the U300. Since I am completely new to kernel development, this might take me a little while, since I have to learn how to actually do this kind of stuff, but since I am affected by this bug, I want to fix it :) Please bear with me while I learn. My goal is to have this fixed in time for Lucid, but I estimate that I'll be able to get it resolved much sooner than that.

Finally, thanks to everyone who posted critical info here, particularly jetdog, ktemkin, and the people who posted their DMI info -- I'm a PHP programmer and barely touch C code, so I was basically just copy-pasting to write the patch, and wouldn't have had a clue how to proceed without the exquisitely thorough explanations and pointers given earlier in the thread.

First is 'Space' keypress and release. The second is turning the wheel one notch Up.
a) the event is repeated 3 times - looks like the anti-repeat in drivers/
b) even with atkbd_setup_
VolumeUp key is depressed (0) then pressed (1) three times
This leaves the button in pressed state, causing the "sticking" behavior.

Tomasz: I wrote the patch against 2.6.33-rc4, so I'm not surprised it doesn't apply to an older kernel. To clarify, are you still getting the user-visible symptoms even with the patch? When I tried it, I stopped getting the symptoms (volume indicator maxing out and flickering, keyboard freezing up, etc.). The volume wheel seemed sluggish/jittery, but it behaved much better. I did seem to still be getting similar codes from showkey -s, but I assumed those were somehow not relevant, since it mostly worked.
I'll try out the sysfs thing when I get access to the machine again. Do you know where this sort of change would be added in HAL/DeviceKit? Are there any example patches? 2.6.32 means Lucid, so a quirk would still be needed if we wanted to fix it for Karmic, I guess (maybe not worth it).

Yes, I still have the user visible symptoms.
I guess the key-up, key-down sequencing is fixed in 2.6.33, so it works for you.

On 2.6.33-rc4 (presumably also 2.6.32), this mostly works:
sudo bash -c 'echo 174,176,`cat /sys/devices/
(I figured out 174,176 by binary search. Protip: don't force_release anything in the range 0-127, since that will prevent keycodes like Ctrl-Alt-F1 from working . . . I had to hard-reset my computer.)
The volume control no longer goes crazy when you turn the dial. But it's not a complete fix -- as noted, the dial sends three or four keypresses at once, so this results in the volume jumping instead of increasing smoothly. A quirk probably does need to be added to the kernel after all, which will cut out the duplicate keypresses. I'll look into writing that.

I took a stab at fixing the "multiple keypresses" thing, but eventually gave up. It doesn't seem worth it -- volume control works okay as-is, and I'm concerned that maybe in some cases it will start emitting only one keypress at a time and break any fix. We just need to wait for userspace support for this quirk detection, I guess? At any rate, now there's a very good workaround with 2.6.32+, it just needs to be applied automatically.

This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:

If you're using 2.6.32 or later, you should be able to fidget with the contents of the force_release file in /sys to add the appropriate keycodes. The exact values can be found by experimentation, and you can add something to /etc/rc.local to set it on startup if you like (changes will not persist across startup).

The former. Pretty much what the volume keys do.

This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '12'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 12's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 12 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:

Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.

I am afraid this bug is still present in Fedora 13 and will test with Fedora 14.

reopening as per comment #27 - please retest
if this was really fixed by the udev-145-22.fc12 update (and there's no regression in newer Fedora) then please close this bug properly, WONTFIX really isn't appropriate for a bug that has been fixed ...

reopening then
if the patch mentioned in comment #20 doesn't fix the issue then we have a problem ...
please check that you have the appropriate rule in place -
# grep TOSHIBA /lib/udev/
ENV{DMI_
and does your model name match one of the product names listed?

Pavel,
it seems you have a slightly different model than the one that was originally reported here. I now made the name matches more liberal, which sohuld also catch your model:

Pavle, would you mind patching your udev rules with Martin's update to test it?
as for the script, the full path is /lib/udev/

Yes, you can run
udevadm trigger --subsystem-

Pavel,
something seems to have gone wrong there:
$ cat product_version
�������
can you please give me the output of
cat /sys/class/
? Does it say something reasonable like "Satellite u300" or just the broken garbage that your tarball has?

Martin,
it is as broken as you see it in the tarball. Binary garbage full of FF bytes.

Pavel,
thanks for checking. I'm afraid there's no generic way to fix this in the rules then :/
You can fix it locally by creating a file /etc/udev/
-------
ACTION=="remove", GOTO="force_
SUBSYSTEM!="serio", GOTO="force_
KERNEL!="serio*", GOTO="force_
DRIVER!="atkbd", GOTO="force_
ENV{DMI_

Whoops, sorry. You need to append a line

# cat /etc/udev/

It did not help. Unfortunately I don't understand it enough to debug.
I've been using fedora for a long time and I learned not to touch the wheel. But I'm still very curious about fixing this. To learn a bit more about udev, if not for anything else.

For me, gnome-shell doesn't get confused anymore. Maybe because of the fix above, maybe not, I don't actually know. I'll test on a fresh F16 install when it's out.

On a Toshiba Satellite Pro U300 laptop (and others with the Pro series), there
is a volume dial on the side of the laptop, which is used to control the sound
volume.
It works on Fedora GNOME 2.22.1, but incorrectly.
Even slightest move up of the dial, moves the volume all the way up. The volume
control beside the clock shows the setting is in effect, also the volume icon
popup shows the volume all the way up.
The same happens with even slightest move the volume dial down. It turns the
volume all the way down, showing the mute sound icon beside the clock on the
panel and on the popup.
Aditionally the move breaks the keyboard handling. After the volume all up/down
keyboard is left in a non-working state. The signalling is still on because the
volume popup stil shows and disappears consistenly showing the max/mute icon.
I tried to see what keycodes the volume dial sends using 'xev', but since the
keayboard handling breaks during the dial move, I couldn't get much information
of it.
To get my keyboard working back, I need to switch to text console (Ctrl-Alt-F1)
and back to graphical console (Alt-F7).
