https://bugs.freedesktop.org/show_bug.cgi?id=34419 Summary: Kwin crashes screensaver exits Product: DRI Version: unspecified Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: General AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: isaac.gerg@xxxxxxxxxxx I am using KDE 4.6 with Kubuntu 10.10. When the screensaver exists, Kwin seg faults in the intel driver code. The crash is reproducible as long as the screen saver has been on "for over a few minutes" meaning that if the screen saver comes on right away and then you move the mouse, the crash doesnt happen. But, if you wait something like 10 minutes and move the mouse, the crash will occur. Details provided below include the debug symbols. If you need any other information, please contact me. Thank you. -- Using openGL for my composting type. Using xorg 1.7.5. Here is the debug dump....
