[intrepid] cannot see touchpad tab in mouse configuration

[zombiepig]

Binary package hint: xserver-xorg-input-synaptics

The touchpad tab is still missing from preferences->mouse, even with intrepid with all updates installed.

I've attached my xorg.log file

What is the output when you run `xinput list-props "SynPS/2 Synaptics TouchPad"`?

Also please post the output of `dpkg -l | grep gnome-control-center`

Looks like you're running an old X server. Are you sure you've installed
all updates and rebooted?

[Timo Aaltonen (tjaalton)]

Try with the numerical device ID instead of the name?

[zombiepig (nyall-zombiepigs)]

that gives me the same error:

I actually get the same error for all devices, eg:

[Marc (m-chabot)]

I got the EXACT same error message using xinput with a Macbook pro 2nd edition...

My Ubuntu 8.10 64bit alpha5 system is up-to-date with all updates and freshly rebooted.

[Timo Aaltonen (tjaalton)]

Please try the driver from my PPA:

http://ppa.launchpad.net/tjaalton/ubuntu/pool/main/x/xfree86-driver-synaptics/

if that doesn't help, upgrade your kernel. There was a new version uploaded today.

[Marc (m-chabot)]

I have to make a correction: I'm on a Macbook Pro 3rd generation.

Same result using xfree86-drivers-synaptics, but at least the mouse pad reacts a bit more, so my mouse movement is normal... but no two-finger scrolling, and no configuration available through GUI.

[zombiepig (nyall-zombiepigs)]

No luck still with 2.6.27-3, and xserver-xorg-input-synaptics 0.15.2-0ubuntu1

[Timo Aaltonen (tjaalton)]

Please attach the output of 'lshal'.

[zombiepig (nyall-zombiepigs)]

Here's my lshal output

[zombiepig (nyall-zombiepigs)]

I'm still seeing the same behaviour with alpha 6, same symptoms as in the previous comments.

[unclebob (ralfhedenhos)]

I have the exact same problem. No touchpad tab, and the same weird output from xinput -list-props ...
I'm running alpha6.

[Lukas Sabota (punkrockguy318)]

hey i'm also having the exact same issue. I have a Dell XPS M1530 laptop. I've attached my lshal output. I'm running the latest 8.10. I really hope this gets resolved before the release.

[GiuseppeVerde (launchpad-digitasaru)]

My trackpad is also not being detected. This is on an EEEPC 901, which is likely to be an important model to support.

I will attach lshal and xinput list output shortly.

Assuming that the default tap-to-click doesn't finish driving me over the edge first when it activates while I'm typing.

[GiuseppeVerde (launchpad-digitasaru)]

Marking confirmed. AFAICS, all information has been provided, and there are a number of reporters.

[GiuseppeVerde (launchpad-digitasaru)]

Update: I found out that my particular problem is that the EEEPC 901 has an Elantech touchpad, which apparently doesn't have a driver, causing the touchpad to be recognized as a Logitech Wheel Mouse (bug #123775).

[Harvey Muller (hlmuller)]

This is also broken on the Dell Inspiron 1420, i.e. the touchpad pad is missing here also. In Hardy the 1420 autoconfigured /etc/X11/xorg.conf with a Synaptics Touchpad section. This is not the case in Intrepid.

`xinput list-props "SynPS/2 Synaptics Touchpad"` results in:

    unable to find device SynPS/2 Synaptics Touchpad

This is to be expected, as `xinput list` identifies the touchpad as "AlpsPS/2 ALPS Glidepoint"

`dpkg -l | grep gnome-control-center` results in:

   ii gnome-control-center 1:2.24.0.1-0ubuntu2

So it looks like the Glidepoint is not being mapped to the Synaptics Touchpad as was the past behavior.

Attaching lshal.log, if there are other requests related to this comment, they will be addressed swiftly.

Thanks,

Harvey

[William Grant (wgrant)]

Harvey: Your touchpad is being recognised correctly (the right driver and capabilities are shown in lshal). What if you list the properties of the proper device name instead?

[Daniel Graziotin (dgraziotin)]

I own a Macbook 3,1. Trackpad/Touchpad is recognized but I cannot configure two finger scrolling / right click support on 8.10 beta. Should I open a new Bug?

[Alex Wauck (awauck)]

bodom_lx, I think your problem is the same one described here. It looks like the touchpad is properly detected on all systems, but something about XInput device properties is broken. In fact, it seems that xinput list-props is broken on all systems, even ones that don't have touchpads.

[Alex Wauck (awauck)]

bodom_lx, I may have misunderstood. Are you saying that you have the touchpad tab, but you can't make two-finger scrolling and right-click support? What happens if you run xinput list-props as described above?

It's actually not broken on all systems; it works on all of mine, and I
don't know of many other cases where it doesn't. It's likely a bug in
xserver, and we're hoping the the new XI property API backport will fix
it. We can expect to see it in not too long, since the beta was just
released.

There are no widgets in the UI for those at the moment. You can,
however, set them using xinput and add them to your session startup.

I'll hopefully be able to expose all properties through the Touchpad tab
for Jaunty, but it's too late for Intrepid.

[Daniel Graziotin (dgraziotin)]

Ok, let's try to be more precise:
As you know, macbooks do have scrolling trackpads, with one single button.
I see the touchpad tab, I may also play with its options but I can't make two-finger scrolling and right-click.
I also tried to follow this Wiki page, even if it's written for 8.04: https://help.ubuntu.com/community/MacBook_Santa_Rosa#Fix%20Touchpad
Obviously, it did not work..

I have a Dell Inspiron 1520 and I clean-installed Beta 1 this morning. I've downloaded all the latest updates. My touchpad works fine for the most part (vertical scrolling but no horizontal, tap-to-click works), however I have no entries at all for the touchpad in my xorg.conf nor do I see the "Touchpad" tab in my Mouse control panel.

I'm using Intrepid kernel 2.6.27-4-generic 64-bit and Gnome 2.24.0.

In Hardy 64-bit I had both an entry in xorg.conf and a Touchpad tab. These have disappeared in Intrepid. I have run dpkg-reconfigure and nothing changed.

The xorg.conf issue isn't an issue - it's quite intentional. Input
devices are now autodetected through hal. The lack of Touchpad tab seems
to only affect some hardware, and is being worked on.

Is this valid for macbooks,too? So there is not the needing to open a new bug, am I right?

For everyone who has been having issues: upgrade (ensure you have the latest updates from the main mirror, not just your local one which might be days out of date!), reboot, and try again.

zombiepig: You need to reboot (or at least restart X).

[Paulo Tanimoto (tanimoto)]

William,

I just upgraded from the main mirrors and restarted. Now xinput gives me something similar to what zombiepig is reporting (Fetch failure), as opposed to an error as before. Setting any option doesn't have any effect.

What info should I provide? Thanks.

[William Grant (wgrant)]

Paulo: `dpkg -l | grep xorg | grep -v video`

Do you have the Touchpad tab visible in System->Preferences->Mouse?

Is anybody experiencing this bug *not* using amd64?

[zombiepig (nyall-zombiepigs)]

i AM using amd64 here

[Paulo Tanimoto (tanimoto)]

I'm on 64bit too. If it really helps to have this tested on i386, I can install it on a spare partition and report back.

[William Grant (wgrant)]

If you can test the beta i386 live CD on identical hardware, that would be excellent.

[Paulo Tanimoto (tanimoto)]

Sure! Just keep in mind that all I can test is xinput, since I don't have a laptop. I'll test the live cd and then install, so I can test the new packages as well. Will report back in about an hour.

[Paulo Tanimoto (tanimoto)]

William,

First result: xinput works directly from the live CD. I can list and change properties just like I wanted in the first place. Would you like me to install and test the new packages as well?

$ xinput list-props "Logitech USB Trackball"
Device 'Logitech USB Trackball':
 Device Enabled: 1
 Middle Button Emulation: 2
  valid values: 0 1 2
 Middle Button Timeout: 50

 Wheel Emulation X Axis: 0, 0
 Wheel Emulation Y Axis: 4, 5
 Wheel Emulation Inertia: 10
 Wheel Emulation Timeout: 200
 Wheel Emulation Button: 4
 Drag Lock Buttons: 0

[Paulo Tanimoto (tanimoto)]

OK -- I installed the i386 image and upgraded from the latest packages from the main servers. xinput still works like it did on the live CD. So it seems that, at least in my case, the issue has to do with x86_64.

What information can I supply from both installations that would be helpful? Also, if you have other bugs that you suspect are platform-dependent, feel free to ask me for a test. Before I wipe out the 32bit installation. : )

[William Grant (wgrant)]

After extensive testing on IRC, I'm fairly sure that it's amd64-specific. At least it seems to never affect i386 machines - other archs I'm not sure about. We're working on debugging it thanks to this new info.

[William Grant (wgrant)]

It seems that libxi or similar is playing up on amd64. GetWindowProperty works fine, but GetDeviceProperty sends something like this to the X server:

  92 27 06 00 04 00 00 00 6d 00 00 00 00 00 00 00 13 00 00 00 00 00 00 00

That and its response decode (with my modified xtrace) to:

  000:<:000b: 24: XInputExtension-Request(146,39): XIGetDeviceProperty property=0x4("ATOM") type=0x6d("Device Enabled") longOffset=0 longLength=19 deviceid=0 delete=false(0x00)
  000:>:0x000b:32: Reply to XIGetDeviceProperty: propertyType=0x0(unrecognized atom) bytesAfter=0 nItems=0 format=0 deviceid=0

The X server's response seems correct, given the bogus data the client gave it.

On i386, it sends:

  92 27 06 00 81 00 00 00 13 00 00 00 00 00 00 00 01 00 00 00 04 00 f5 05

Decoding to:

  000:<:000b: 24: XInputExtension-Request(146,39): XIGetDeviceProperty property=0x81("Device Enabled") type=0x13("INTEGER") longOffset=0 longLength=1 deviceid=4 delete=false(0x00)

[oupablo (oupablo)]

The original beta for Intrepid with the .5 headers recognized the touchpad fine. With the install of the .6 and .7 headers the touchpad, xserver-xorg-input-synaptics wasn't installed. After installation the touchpad worked fine. I'm not sure why the update for xserver didn't find the touchpad though.

[Paulo Tanimoto (tanimoto)]

William,

Very strange, could it be that the x86_64 version is using incompatible variable types? So the issue is more low level than what I had thought, since you found this behavior with libxi. Does hal rely on it too to change settings? I ask that because in my case making changes through hal seems to work.

[William Grant (wgrant)]

Paulo,

hal's option setting is just like xorg.conf's; it's done only upon device initialisation, and without the usual client/server model that X uses. xinput and the Touchpad tab in gnome-mouse-properties use XInput device properties, which are settable at runtime through the X11 protocol stream itself. libxi handles the client side of the required X11 extensions. It looks like some parts are being swapped - compare the incorrect data sent and what I believe should be sent:

Bad: 92 27 06 00 04 00 00 00 6d 00 00 00 00 00 00 00 13 00 00 00 00 00 00 00
Good: 92 27 06 00 6d 00 00 00 13 00 00 00 00 00 00 00 01 00 00 00 04 00 00 00

[Paulo Tanimoto (tanimoto)]

Ah, now I see, thanks for the explanation.

Wow, good eyes. I had only noticed that the first four values were the same, then thought there was corruption. So basically 04 00 00 00 is being inserted in the middle, when it should come at the end. Unfortunately, I don't know what to make out of this. If you have any suspicion of which source code I should look at, please don't hesitate to give me directions.

[William Grant (wgrant)]

gcc appears to feel it necessary to reorder those particular request and reply structs on the client side.

[William Grant (wgrant)]

jcristau worked it out - sizeof(Atom) is 8 on amd64, as it's defined as a long. Making it a CARD32 instead works.

[Paulo Tanimoto (tanimoto)]

Nice, this is great news! Thanks for staying on top of it, William!

[Paulo Tanimoto (tanimoto)]

William,

I downloaded the patches, applied them, and rebuilt the packages. It works! So my particular problem is solved. I hope this also solves the issue that other people were seeing. Thanks again.

[zombiepig (nyall-zombiepigs)]

I can also confirm the proposed patches fix the problem for me. I get correct output from xinput, and more importantly, the touchpad tab is reappearing in mouse configuration!

Nice work :)

    amd64. Thanks to Julien Cristau for working this out. (LP: #267611)

How can I apply this patch to my system? I'm on Ubuntu 8.10, and I believe this patch will fix my problem.

[William Grant (wgrant)]

The patch is already in Ubuntu 8.10. What is this problem that you are having?

[alecwh (alecwh)]

The problem is solved, it was something unrelated. I was unaware that 8.10 now uses "FDI" files for configuration.

I am having some problem with my synaptics touchpad using updated packages since yesterday :

I'm posting mine thinking that maybe someone will be able to help me !

I notice this is marked fixed for -input, however it still has an open task for -synaptics. Is there still something needing to be done for -synaptics or can this task be closed as well?
