Xorg instantly SEGFAULT when plugging in a usb wireless hid

[Peter Kopias]

 What I think should have happen: Xorg should not die with SIGSEGV
 What did happen: Xorg died with SIGSEGV

 I've just upgraded from ubuntu 11.10 - desktop - x86 ubuntu (gnome).

 After reboot X did not start. I tried to install missing packages, with no success.

 Then I looked at xorg.log, and found that my "Chicony USB hid" killed it.

 I've got an USB keyboard (logitech), a normal usb mouse, and a wireless keyboard+mouse combo device plugged in.

 After removing the latter from the usb hub, X runs fine.

 If I plug in, Xorg INSTANTLY dies with segfault. (I can repeat it, so if you tell me to install some debug symbols, I can recreate the sigsegv any time)

 Xorg.log looks like this: (full: http://pastebin.ubuntu.com/933492/ )

[Peter Kopias (petros-k)]

I've attached the Xorg.0.log , and lspci and lsusb outputs AFTER plugging the Chicony "KG-06-09" wireless HID (keyboard with touchpad) in.

I was able to use this same config (keyboard,mouse,keyboard+touchpad) with the 11.10 Xorg.

This video shows the keyboard, the usb-dongle, the working Xorg, the plugin, the segfault and the log.

[Peter Kopias (petros-k)]

Thanks for the tip, but id did not solve my symptoms.

(BTW I can live without this keyboard, but as it was working well a day ago with 11.10, it's probably some bug implemented since that revision, maybe affecting a few other guys when stable 1204 release happens. :) )

Using this: https://launchpad.net/~bryce/+archive/lp973297 (and update-upgrade-stop-start of course), the same sigsegv happens.

 - I've tried plugging the usb keyboard and usb mouse out, before plugging the donle in (with no effect)
 - I've tried to change the usb setting in my bios: "Legacy usb support" "auto"=>"Disable" (the sigsegv still happens)

 After this bios tweak I see this in my logs:

 So propbably legacy usb support isn't that bad for a keyboard. :)
 (If it's too slow, i'll have to use bzcat >a.out instead of cat >a.out as I do now. :))) )

Hi,

I have exactly the same error. Instantly after I plug in my USB receiver for wireless keyboard graphical environment crashes. It started to occur immediately after release upgrade to 12.04. Before that there were no problems (I've been using this keyboard for couple of years without issues).
Upgrade process was smooth, software is up-to-date, in BIOS I have enabled USB legacy support.
Below you can find my Xorg.0.log.
