Xgl crash when pressing numeric keypad

[bijwaard]

Binary package hint: xserver-xgl

Dear all,

I upgraded to ubuntu hardy (8.04) a week ago (and am up-to-date with current patches) and now get Xgl (Installed: 1:1.1.99.1~git20080115-0ubuntu1) and Compiz (Installed: 1:0.7.4-0ubuntu6) crashes that take down my X session when I press the 7 (Home) button (or any other) on the numeric keypad of my keyboard. This happens every time, regardless of the NumLock status. I have visual effects set to extra, my card is an Nvidia: 01:00.0 VGA compatible controller: nVidia Corporation NV15 [GeForce2 GTS/Pro] (rev a4), I have a Dell AT101W keyboard. The Xorg log is attached. I opened a thread on ubuntu forum (http://ubuntuforums.org/showthread.php?t=785176), but did not get a reaction there.

There are no indications in the Xorg logfiles, only in the kernel log:

I just got another Xgl followed by compiz crash by pressing a key on the keypad, note that the compiz crash is different from above. Or does the Xgl crash take down compiz?

I can confirm this behavior. It's a pretty frustrating one - I've been bit by it three times in the past couple of days - hope you can find a fix soon! :(

This bug is a duplicate of #31907.
I got a resolution to this in the ubuntu forum: http://ubuntuforums.org/showthread.php?p=5025680#post5025680
Resolution in hardy is to remove the package xserver-xgl which seems obsolete, and optionally switch to normal numeric keypad using System/Preferences/Keyboard/MouseKeys tab and unselect "Allow to control the pointer using the keyboard".

using System/Preferences/Keyboard/MouseKeys tab and unselect "Allow to control the pointer using the keyboard". did it for me. I did not uninstall xgl.

xserver-xgl has been deprecated upstream, and removed from Intrepid. Closing the bug as won't fix.
