Is it possible to get a backtrace when the system freezes completely? I tried to follow the directions on http://wiki.ubuntu.com/X/Backtracing. After booting the system with Driver "i810" in xorg.conf to avoid the system hanging at boot, I ssh'ed in from another computer, stopped gdm (/etc/init.d/gdm stop), changed the driver to "intel" and started "gdb /usr/bin/Xorg". At the gdm prompt, I entered "run -keeptty -dumbSched". After a few lines of output from Xorg, the system froze completely, including the network connection going down, so it was impossible to enter "backtrace full". I have attached the output on screen from editing xorg.conf until the system freeezes. Did I do anything wrong?
Would it be helpful to have the ouptut of "strace /usr/bin/Xorg -f -oOutfile" or simlilarly with ltrace? This seems to hang even when I use the i810 driver, but the system doesn't freeze completely then (I can still ssh in). ** Attachment added: "Attempt to debug with gdb" http://launchpadlibrarian.net/14676732/gdb_attempt1.log -- [Hardy] gdm freezes system randomly at startup (965Q) https://bugs.launchpad.net/bugs/232026 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
