Bug Description
On my Dell inspiron 9300 laptop under intrepid (hardy did not have this problem), when I type FN + Arrow keys to change the screen brightness, Most of mouse and keyboard keys stop working.
For an example : I can't type any text anywhere, ALT + F4 does not close any window, mouse clicks "partially" opens the gnome-panel menus, isn't able to close windows with the right-top x, but mouse click is still able to move a window..
screencast : http://
This bug is reproducible under both metacity and compiz, and not caused by a BIOS password.
A quick workaround to bring back things to normal is to switch to a VT and go back to Xorg with CTRL + ALT + F6 and CTRL + ALT + F7
When changing screen brightness, I get this in Xorg.0.log :
(II) AIGLX: Suspending AIGLX clients for VT switch
(II) Open ACPI successful (/var/run/
(II) AIGLX: Resuming AIGLX clients after VT switch
(II) AlpsPS/2 ALPS GlidePoint: x-axis range 0 - 1023
(II) AlpsPS/2 ALPS GlidePoint: y-axis range 0 - 767
(--) AlpsPS/2 ALPS GlidePoint touchpad found

Probably I am experiencing a similar bug on my Dell M1330: my keyboard becomes non-responsive in X after using any of the keyboard shortcuts (volume, brightness, etc.)
However, unlike Saïvann Carignan, I don't have any problems with shutdowns.

Strangely, just switching to the text terminal (Ctrl-Alt-F1) and back (Alt-F1) seems to get the keyboard working again!

By and large X is no longer involved in hotkey handling, however the new -evdev sometimes triggers weird conditions, so moving the xorg component to -evdev on that basis.

In the description you list log output that occurs when changing brightness. Does that output occur before or only after you do the vt switch workaround?

Bryce Harrington : The log outputs in the description appears *after* switching back to VT7 . I attach a modified Xorg.0.log that describes each of my actions followed by Xorg log outputs. This Xorg.0.log is on the same laptop opensource driver (not fglrx).
Saivann Carignan (oxmosys) wrote : | #15 |
Bryce Harrington : Is there any task that should stay open for acpid, or this bug is entirely caused by evdev?
Bryce Harrington (bryce) wrote : | #16 |
It should stay open for acpid. As I mentioned, by and large X is uninvolved with hotkey stuff now, so it's probably more likely to be in acpid or some other component than in X. But it needs deeper analysis to determine what component is at fault.
Especially since looking at your log, there isn't evidence that X is doing anything unusual at all when the hotkey is hit. The log's contents is entirely typical for performing a vt switch. In other words, so far there is no evidence that this is an X bug.
At the same time, there isn't evidence that it's *not* an X bug, so we can't yet close out the task. But if it is X, -evdev should be the starting point to examine, since that's the thing that has changed the most with respect to keyboard stuff. (It could also be xorg-server).
I'll post another comment with some debugging advice.
Bryce Harrington (bryce) wrote : | #17 |
Some hotkeys are handled by gnome-power-
Experiment with using the brightness keys at the vt console, with and without X running. Experiment with them in X but with gnome-power-manager shut off. Use xev to see what key codes (if any) X sees. Here's a xev command string that makes the xev easier to read:
xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'
More info on debugging hotkey issues is available at this link:
https:/
If the problem is in a binary application like gnome-power-manager or pm-utils, you may find strace output of it to shed some light.
If it's a hal problem, then comparing lshal output before and after the brightness hotkey is hit might be worth looking at; in theory the lshal output should be identical, so if there is any difference it might hint that the problem lays deeper down.
On some systems there are scripts from acpi-support that play a role in handling the brightness keys. These are in /etc/acpi/. I have a Dell laptop too, and these scripts don't have an effect for me, so I'm guessing this is unlikely to be the case either for you, but I don't know the specifics of your hardware so it's certainly a possibility.
Hope this helps

I can still change the brightness when the rest of the keyboard and menus stop working.

xev only reports a keypress after switching to VT1 and then back to VT7.
It is:

Given the above, and that it starts behaving once gnome-power-manager is turned off, it's starting to sound like a bug in gnome-power-
Given that your hotkeys work but the rest of the keyboard doesn't, and that lshal output hasn't changed, it sort of sounds like something is stealing your keyboard device. Presumably X is able to reclaim it from doing a vtswitch. Not sure what would cause that.
Please attach your lshal output.

I have a simalar problem with 8.10 on a dell latitude d600 everything is fine untill the brightness changes (wether i doit using fn+up/down or ubuntu aotu changes because i don't have the ac power adapter plugged in). Then no keyboard key work except ctrl+alt+backspace and the mouse buttons don't work, only mouse movements do. also when I change brightness with keyboard it changes but the brightness indicator panel doen't show and cpu usage goes straight to 100% and stays there, I am thinking it is haveing a problem opening the indicator panel. also can't change volume with keyboard before or after the main problem insues.

I have been experiencing this as well with Intrepid on a D600 as well. In fact I didn't realize the problem was related to the use of Fn + hotkeys to change the brightness, until googling the issue. When the issue occurs, the menus in the panel will not open. Clicking the mouse will highlight the Application Places menu, etc, but it won't open until I switch a console and then back to X with ctrl-alt-f1, and ctrl-alt-f7. Clicking on some of the other icons in the panel will work, but results vary.

Unfortunately I'm just the X guy, I'm not really intimately knowledgeable about what's going on inside gnome-power-manager so can't give much advice here on out.
It sort of feels like something is stealing the keyboard/mouse devices away from X, and then the vt-switch remaps things back together possibly. I'm not at all certain what could do this. On a lot of hardware there are separate devices for the keyboard, mouse, and hotkeys; on others these are mixed together in weird ways. I could vaguely guess that some weird combination could lead to things getting stolen from X in unexpected ways, but that's just a vague guess. It would show up by running `xinput list` and analyzing how the hardware's inputs are mapped.
Ted Gould (ted) wrote : | #33 |
@Saïvann Carignan
Could you please grab a gpm.log with and without that patch?
It would seem to me that without that patch that GPM would ignore all keypresses that come as keysymbols. I'm curious if backing that is just stopping GPM from responding to brighness, not actually solving the problem.
Thank you.

Mario suggested that this bug may be related to #261721, and that testing against an earlier 2.6.24 kernel with the same version of gnome-power-manager may be of use to identify if g-p-m is not bugged.

I found one of my systems reproduces the issue consistently. Of interest, booted to root with no X, showkey does not show any output when hitting the brightness keys, however the brightness does change correctly.
Bryce Harrington (bryce) wrote : | #36 |
On further analysis, it's only the key release event that doesn't produce output. Key down generates a keycode press.
And I see what's going on in X - it's not that the device itself is stolen, just the focus. The mouse still works (you can click on the firefox icon and launch it, interactic with its buttons, etc.) but you just can't get the keyboard focus returned to it.
I'm not seeing the OCD displayed when gnome-power-manager running, but the issue clearly occurs only when g-p-m is running, so it's looking fairly solidly that g-p-m is taking the keyboard focus on the keydown brightness key events, and hanging on to it expecting a keyup event which never comes.
So I think the key up/down handling logic in g-p-m needs additional thought in light of situations like this, where the kernel isn't passing up the key-release events.
I'm unclear of the role the patch for 280646 is playing here. I *think* it is not causing the bug, but rather exposing the situation where the bug occurs. My guess is that the patch enables g-p-m to handle the key when previously it ignored it and let the hardware handle it.
In any case, I think we need g-p-m folks to analyze this more thoroughly. Ted?
Bryce Harrington (bryce) wrote : | #37 |
Since it's narrowed to be a kernel and g-p-m issue, we can eliminate -evdev at this point.

The only thing that I can figure is that in this case GPM is swallowing
the keypress, while in others it's letting GDK take care of it
completely. I'm unsure why that would make a difference, I've sorted
through the GDK-X11 source code and it all looks straight forward. I
don't see any focus locks or anything of the such.
The only thing that I could see is changing it so that GPM never
swallows the keypress. In theory this shouldn't change anything as
nobody else should be looking for it.
Could someone who can recreate this try changing this code in
src/gpm-button.c:
egg_debug ("Key %i mapped to HAL key %s", keycode, key);
g_signal_emit (button, signals [BUTTON_PRESSED], 0, key);
return GDK_FILTER_REMOVE;
}
So that it it returns GDK_FILTER_CONTINUE instead of
GDK_FILTER_
Thanks!

Yes. Sorry.

Ted Gould : I tried what you suggested, I changed GDK_FILTER_REMOVE to GDK_FILTER_CONTINUE in src/gdm-button.c so the source looked like this :
egg_debug ("Key %i mapped to HAL key %s", keycode, key);
g_signal_emit (button, signals [BUTTON_PRESSED], 0, key);
return GDK_FILTER_
}
I built, installed and restarted gnome-power-manager and tried to reproduce the bug. Result : nothing changed, I'm still able to reproduce the bug when pressing FN + arrow.

For release notes:
== Using Brightness Function Key Combination Breaks Keyboard and Menus ==
On some laptops using the function key combination to change the brightness can result in a loss of most keyboard control and an inability to fully open menus.
If you lose keyboard control do the following:
Ctrl-Alt-F1 - Brings you to a text console
Ctrl-Alt-F7 - Brings you back to your desktop

It may also be worth noting that opening gnome-power-manager and manually changing brightness with the corresponding slider makes everything (keyboard, menus, etc...) returns to normal.

After using Fn:
1. Left-clicking on menus causes them to be highlighted, but they do not open up. (Normally they open on click, even without releasing the button.)
2. Mouse pointer behaves erratically. It responds, but jumps around at random.
3. Process hald-addon-
Confirmed that (Ctrl-Alt-F1) and (Ctrl-Alt-F9) makes it work again and undoes all of these problems.
After clicking menu and then using this fix, menu is still highlighted, and hovering over it opens it up the rest of the way, without clicking anything.

Turning screen brightness up or down with Fn+Up, Fn+Down results in keyboard not working.
While keyboard is not working:
1) Mouse is still functional, no problem with pointer moving erratically;
2) however most menus are not responsive (confirming Endolith's point 1.);
3) process hald-addon-
4) Fn+Up/Down still works to change screen bightness
Following action bring keyboard back to normal:
1) Switching to VM (Ctrl+Alt+F1) and back (Ctrl+Alt+F7);
2) Killing process pgnome-
3) Waiting about 10-15 min;
Other combinations of special keys, such as Fn+PageUp (sound volume up), Fn+PageDown (sound volume down), Fn+End (sound mute/unmute), Fn+Ins (Print Screen) are fully functional and do not cause any problem. However, these do not work while keyboard is blocked after using Fn+Up/Down keys.

I have a very similar problem with 8.10 on my Dell Inspiront 640m (equivalent to the E1504)
I have the same problems as Karl M except I do not have anything using large amounts of CPU when the keyboard is non responsive.
One other strange behavior I noticed is that when the gnome-power-manager is on there does not appear to be a one to one correlation between pressing fn-up/down and brightness level changes. However the brightness changes just fine(aka one step per press) with the gnome-power-manager off).

Here's a question for those that posted, what graphics card and graphics driver do you have? Could these be related to the now unsupported ATI 9xxx series cards in fglrx, thus forcing us to use the default MESA drivers?

The mouse is functional and usable, but occasionally jerks around. Maybe it's happening for you too, but not as noticeable?
"Here's a question for those that posted, what graphics card and graphics driver do you have?"
Mine is Nvidia, though that also failed during the upgrade, and I haven't gotten it working yet, so I think it's using vesa drivers as a fallback.

well, I'm not sure how to see what driver i'm using, but i'm not using any

I don't think it's unsupported ATI cards... at least on my machine.

The Dell Inspiron 5100 I have has ATI MOBILITY RADEON 7500C card, and I am using the open source driver that got installed by default.
To Endolith:
"The mouse is functional and usable, but occasionally jerks around. Maybe it's happening for you too, but not as noticeable?"
- I really don't see anything like that. But I don't think these details are so important. I think we are all seeing the same bug that leads to broken keyboard plus some variations in behavior for different machines.

This is a kernel problem that affects Dell laptops. It has been fixed upstream by Matthew Garrett. The issue is that some keys on a Dell laptop do not produce a key down, key up sequence when the button is pressed, and instead just produce key down and NOT key up. This confuses X greatly, as more and more keys are being pressed "together". This is fixed in 61579ba83934d39

OK, I have a Dell Inspiron 6400 (UK MM01) model, and I am seeing the same issues only with these keys:

So this Dell bug seems to affect different models in different ways.

This works good. My wireless key now functions again, and the CDEject key (XF86Eject) when mapped to Fluxbox keys file works too without locking up the desktop input.
xev reports all fn keys to work properly (apart from F3, and F8 that don't report anything, I don't know why).
I would say as this affects so many people that purchased shipped Ubuntu Dell portable systems, it should be upgraded to a more important category.

I had this problem on Dell Inspiron 5100, Ubuntu 8.10 and now that I updated the kernel to 2.6.27-8 the problem persists exactly the same way as I described it before. Is this update supposed to fix it?
I am not sure if the following is relevant, but here is what I think may be the reason for this.
I looked at the changes to /drivers/
DMI_
However, on my system, when I execute
$ sudo dmidecode | grep Vendor
the output is:
Vendor: Dell Computer Corporation
which, although referring to the same manufacturer, is still entirely different string. Maybe the problem is that different laptops identify themselves with slightly differently and the patch is not general enough to account for all of them?
Attached is output after sudo dmidecode.
Lethe (nick-ukfsn) wrote : | #89 |
Karl M., interesting.
I have reported this to the kernel guys, as obviously the patch fails to cover all the vendor names Dell use, and as in your case, the fix is not applicable (but still needed).
I guess the kernel guys will need to be told as new and different vendor monikers appear.

What is the model name, BTW?

So it is me with Dell Inspiron 5100 again. To answer Lethe's question, the model is identified as:

I attached the output of dmidecode on my laptop previously, I understand that most info should be there. Please let me know if you need more information beyond that.
I recompiled the kernel with the only change being that in /drivers/
DMI_MATCH(
replaced with
DMI_MATCH(
and now the recompiled kernel indeed does not have any problem with Fn+Up, Fn+Down keys on my machine. Of course, this kernel would not work for those Dell laptops which are from "Dell Inc.". So it is really about differences in how these laptops identify themselves.

confirming that 2.6.27.8 kernel fixes the problem on DELL Inspiron 9400; (Identified as "Del Inc."). xev no longer shows the KeyPress/KeyRelease loop, and OSD for brightness is working.
However a minor issue I noticed was that brightness up/down steps were not consistent. After going to 100% brightness and reducing using Fn+down, I hit minimum brightness when OSD shows only 50%; OSD goes down to 0% if I keep pressing Fn+down; Now when I increase via Fn+up, it starts to increase properly and and brightness hits max when OSD shows 100% (which is correct).

I'm going to vote for gpm being an issue too. I've given up on this getting fixed properly soon, and went back to 8.04. I don't have any issues with input and the OSD for the screen brightness works fine. Just to be clear, DOWNGRADING the distribution works, but not downgrading the kernel, which I tried earlier. To be sure, the cause is some quirky hardware, but it seems more logical for gpm to be able to handle the unexpected behavior more gracefully, rather than patching the kernel for random bits of hardware, that may or may not need a work around.

With 2.6.27-10 from -proposed the keyboard control for backlight works with 7 levels of dimming up and down.
However, the brightness OSD is still not showing when using the keyboard shortcut. It is only showing briefly when I plug-unplug the power cord and g-p-m updates the brightness level automatically.
In fact -10 did not bring visible improvements, or regression, for me compared to -8.

Hi Jimig,
Have you upgraded to 2.6.27-10? I have an Inspiron 6000 and on -8 and -10 the problem of the locked keys is sorted. I still hace a hassle with the gnome-power-manager OSD and brightness applet not showing the current level.

* Confirming comment #91 by Daniel Knitt-Frank: When I got locked due to Fn+up/dn, then when I used Ctrl+Alt+F{n} (n = 1..6) for the first time (as the suggested for workaround), the X screen somehow pops back in before I even pressed Ctrl+Alt+F7. I had to press Ctrl+Alt+F{n} then Ctrl+Alt+F7 again to fully restore the functionality of keyboard (just to be safe). Weird.
Also related, probably: after the suspend and resume, sometimes the LCD brightness slider would not work anymore. But later on (don't remember whether I suspended again or not in between) it worked again. I may need to open a separate thread for this bug. But for now I just want to make a comment on that.
My DMI vendor string is also "Dell Computer Corporation", so I'm out of luck with the fix already in the kernel. When will somebody act upon this?

I installed the newest gnome-power-manager (2.24.0-0ubuntu8.1) on my Dell Lattitude D600. The result was mixed (I am using xubuntu 8.10, BTW):
* Now I can see the OSD when adjusting the brightness up and down. However, the keyboard was still locked as a result of pressing Fn+Up or Fn+Dn.
* On one occasion I did not see the OSD, but somehow pressing Fn+Up or Fn+Dn did NOT lock my keyboard. I will find out how I could get to this situation.

I have the same issue on a Dell precision M4300. It also happens when not using hotkeys, almost randomly, a few times a hour. Under both 32 and 64 bits.
As a side note, when the problem happens, i press ctrl-alt-F1 and the screen flickers to text mode, but very often comes back "by itself" to graphic mode.

Hi everybody,
There has been no further discussion from anyone for a little while; new posts seem to repeat the existing bug description. I am surprised that such a long bug report hasn't be acted upon promptly, although the fix is easy to make (albeit being a dirty workaround):
This dire situation we are having with Dell laptops can be easily fixed if the patch proposed in comment #142 is incorporated into the current file atkbd.c in the Linux kernel, by adding an additional record in the atkbd_dmi_

I agree totally with Wirawan. This bug, though small, is very serious. I found the workaround Ctrl+Alt+Fx by myself because I wanted to check the problem from the command line, but there are more and more users out there who have no idea that their Linux has six text terminals. The only thing they know is: if I use completely normal keys on my keyboard, Linux crashes. Their conclusion will be that Ubuntu, or Linux in general, sucks.
My setup, in case anybody is interested: Inspiron 1150, Linux inspiron1150 2.6.27-9-generic #1 SMP Thu Nov 20 21:57:00 UTC 2008 i686 GNU/Linux.

The original upstream fix is present in the 2.6.27-11.22 kernel in intrepid-proposed, but this fix only covers the "Dell Inc." case; rolling back the bug state, since it appears another fix is still needed here.
Andrew, the date of "intrepid-updates" is actually the deadline after which updates for intrepid *stop* being published; this fix can be made available to users of Ubuntu 8.10 any time before that, developer time allowing.

This is on my Dell Studio 1535, I bought it from dell.com/ubuntu w/ Hardy on it originally and the brightness function key combo worked fine on Hardy, but after upgrading to Intrepid, weird things happened with the brightnes function keys and applet.
If I try to change the brightness, the bar on the brightness applet that comes up is not synchronized with the actual brightness of the screen. If i go to lower the brightness, the screen will get dimmer in increments as it's supposed to, but the bar on the applet with drop to the far left like I turned the brightness all the way down. The keyboard also doesn't respond properly after adjusting brightness, and the applet doesn't go away. If I switch to another tty and back again, all is normal, the brightness applet is gone and the keyboard works fine.

On my system, at least, a variant of Rich's workaround is serving me just fine. I added the following to my ~/.xmodmaprc :

This prevents those keycodes from triggering the Gnome Brightness Applet entirely, which seems to bypass the problem. The screen brightness still changes. I think I personally may keep this enabled even after this bug gets resolved. I see no value in having a little slightly-
