First of all, as I explained above this bug does not allow me to launch any "sudo" operation and in particular I cannot start "sudo gdb" so I will not be able to obtain a backtrace. This is in itself a problem because it means some X.org bugs cannot be efficiently debugged at all (it's probably going to be a looong time before airlied's non-root x.org patches, see http://airlied.livejournal.com/59521.html, make it into ubuntu so maybe someone should start to figure out what on earth could possibly block ALL SUDO operations on the system?).
Moving on, here is some of the additional information (this information was extracted after a reboot, when the system was operating connectly again): "uname -a" reports Linux 2.6.24-16.386 #1 Thu Apr 10 12:50:06 UTC 2008 i86 GNU/Linux ** Attachment added: "dmesg" http://launchpadlibrarian.net/14701101/dmesg.log -- 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
