Desktop Graphics malfunction and soon System crashes when compiz enabled (nVidia, ASUS U3s, Ubuntu 8.10 and 8.04)

[Aiden83]

Binary package hint: compiz

I have had this problem with both Ubuntu 8.04 and now 8.10. The problem only occurs with advanced Compiz graphics enabled. The problem is also most evident when the CPU monitors in the Ubuntu panel are incorrectly displayed as blank boxes instead.

Also,a similar problem (which only occurs with Compiz enabled) occurs very often when I try to resize a window. In this case the entire display (progressively) crashes, with the mouse barely working at all, then not at all. The windows are displayed with patches of incorrect graphics. The Ubuntu panel becomes patchy with the CPU monitor graphics displayed as blank boxes instead. CTRL+ALT+DEL does not work. I have to force restart. This may be related to this reported bug.

Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

I need to know to what dbgsym packages do I need to install to get the backtrace. eg, is it compiz-core-dbgsym,
compiz-gnome-dbgsym?

To start the backtrace, I also need to know the process ID pid. Is it the compiz or compiz.real process?

How do I link a bug to its package to its process?

I actually froze my system tring to start the backtrace.

Also, I noticed that without compiz enabled, the CPU monitor still often loads as a patch, on both this and my other intel quad core 2 6600 ASUS P5K3 system.

Thanks for your bug report. Unfortunately this report does not have a backtrace which makes it very difficult to investigate the problem. Due to the number of crashes that are currently being reported against Compiz we will close this bug assuming it is a duplicate of one of the existing crash bugs at http://bugs.launchpad.net/ubuntu/+source/compiz/.

For more information on problems with visual effects see http://wiki.ubuntu.com/VisualEffects.

If you are able you can try to obtain a backtrace using http://wiki.ubuntu.com/DebuggingProgramCrash. If you think the backtrace is unique please attach the file to the bug report and mark the bug as "New".
