Bug Description

Binary package hint: libxrandr2

X crashes in the Jaunty Alpha 2 Live CD and yesterdays daily after Gdm login. It works at first if I have removed compiz but afterwards it crashes again with this backtrace. It seems to work fine with vesa driver.

[lspci]

Last dmesg lines are important I guess.
[ 698.897200] Xorg[4650]: segfault at bf55afe0 ip 080f6511 sp bf55afe0 error 6 in Xorg[8048000+199000]
This message doesn't appear twice I just created the backtrace after the second crash.

This time X started without Compiz fine again. After starting the 3D desktop with "compiz --replace" I got this backtrace:

Program received signal SIGSEGV, Segmentation fault.

So both seem to be connected. I also got the Xorg.0.log message before Compiz "exaCopyDirty: Pending damage region empty!" and afterwards the usual dmesg output "[ 44.072877] Xorg[3470]: segfault at bf417fc0 ip 080f64e6 sp bf417f90 error 6 in Xorg[8048000+199000]".

I have compiled Jaunty xorg with the patch and it works fine but I guess it should be in newer xorg releases anyway.

I'm having this problem with intel 915. I can only log in to Jaunty in Failsafe Terminal mode, and trying to adjust the Appearance crashes X. Hopefully the patch will make it's way into Ubuntu soon.

Actually, the latest Jaunty daily works for me now. I'm changing libxrandr back to invalid, as I was probably incorrect in marking it confirmed.
