Ah, thanks for the tip unggnu, that's a nice workaround for textured video.
By the way, I was able to figure out why my backtrace didn't have full symbols. The two dbg packages you mentioned does not cover everything, it's also necessary to install libgl1-mesa-dri-dbg in order to get symbols for i965_dri.so functions. So next time you see an intel x.org driver bug, tell them to install these dbg packages: xserver-xorg-core-dbg xserver-xorg-video-intel-dbg libgl1-mesa-dri- dbg Thirdly, I also discovered one more clue about this bug. I tried to turn off Compiz and then the bug doesn't repro at all. I ran the screensaver for three days and three nights, no sign of the bug. When I turned compiz back on the bug happened again after just 2 hours. -- periodic Xorg crashes w/ high cpu usage after OpenGL screensaver [965GM] https://bugs.launchpad.net/bugs/234768 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
