I can confirm this bug, been having it in gutsy too. for some time it seemed to be less frequent, then - about a week ago - an update for kernel came that made this bug readily reproducible again.
my system: Kubuntu Hardy Intel GMA965/X3100, default drivers electricsheep screensaver. I seem to be having those hangups not only after/while the screensaver is running, but also sometimes just after loading KDE or plugging- in/disconnecting the power chord. more details (dmesg, lspci, xorg.conf) coming up tomorrow. -- 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
