Bug Description

New computer core 2 duo, nvidia 8400GS card (DVI+VGA).

Using two screens, with Compiz.

Machine has been up 3 days (Hardy was it's first and only OS), and has xorg crashed 6 times so far.

No pattern to the crashes, but have all been while computer was in active use.

Will try turning off 3d.

Using the most recent Hardy Heron.

I have the same bug.
Core 2 Duo
Dual nVidia Quadro 570's
Quad-monitor (dual twinview) with compiz
This bug is completely repeatable for me, everytime I run qGo and try to observe a new game Xorg crashes immediately.

Can you try this and see if it solves the problem?

Add the following section to your xorg.conf (if such section is already available, just change the option to "Disable"):

Section "Extensions"
    Option "Composite" "Disable"
EndSection

That fixed the problem! Any further information on what "Composite" is and why it breaks qGo?

I have noticed this problem with Quadro cards. It looks like the UBB (unified back buffer) of Quadro cards conflicts with the Composite extension.

I also have the same problem, I use Kubuntu 8.04 on Core2Duo E7200, GeForce 7300GT. The crash happens from time to time (at least once a day), in various circumstances - I can't find any rule for this.
