Bug Description

Binary package hint: xserver-xorg-input-evdev

In Natty, X (and gdm) recently started to crash on startup when trying to detect my wireless mouse:

Program received signal SIGSEGV, Segmentation fault.

unpluging that usb radio transceiver and plugin another one (from another brand) allowed me to start X.

Hi Fabien,

Please you install this previous version of xserver-xorg-input-evdev:

https://launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/1:2.6.0-1ubuntu6/+buildjob/2236576/+files/xserver-xorg-input-evdev_2.6.0-1ubuntu6_i386.deb

Then log into X, save the X log, and attach it here. Also, run:

$ xinput list

Find the device that is causing the crash with the latest evdev. Note it's device id number. Then run:

$ xinput list <device number>

Save the output and attach it as well. Finally, run the following:

$ xinput list-props <device number>

Save the output and attach it as well.

Thanks!

Unfortunately, the evtest log from Fabien was for one of the non-crashing evdev nodes for his device. I would appreciate it if anyone could follow these instructions to get a device recording so other can test out the device virtually:

Stop X so it doesn't crash anymore:
1. logout
1. Enter VT 1 by pressing ctrl + alt + f1
2. login to the console
3. $ sudo stop gdm

Record the device properties of the crashing event node:
4. plug in device
5. $ sudo evemu-describe (/dev/input/by-path/name where name is your device name) > device.prop

Return to X:
6. unplug device
7. sudo start gdm

There may be multiple names for your device. If you are unsure which event node is causing the device to fail, please get device files for them all.

Thanks!

Please test the xserver-xorg-input-evdev package here:

http://people.canonical.com/~cndougla/utouch/

I believe this should resolve the issue. If so, I'll try to get this in before Alpha 3 is released.
