Please install the following debug symbol packages: sudo apt-get -y install libc6-dbg xserver-xorg-core-dbg libgl1-mesa-dri-dbg libgl1-mesa-glx-dbg xserver-xorg-video-radeon-dbg xserver-xorg-video-ati-dbg libx11-6-dbg libice6-dbg If you can capture the stacktrace again with these debug symbols we might be able to get function names for the remaining stackframes as well. Or, even better.... do you have access to 2 computers? If so, it would be useful if you connected to the affected system with ssh and then attached GDB to the X process. Once the bug happens again, please run "bt full" in gdb and paste the output here. To make that more convenient you can first activate logging in gdb using "set logging file xorg_backtrace.txt" followed by "set logging on"; all subsequent gdb out is then recorded to this file. Mored detailed information about obtaining good backtraces is available here: https://wiki.ubuntu.com/X/Backtracing Is there anything else what makes your installation unusual? Is this a plain desktop ubuntu install or is this machine connect to a big office / school network with LDAP authentication or such? -- Random xorg crash with gdm_slave_xioerror_handler fatal error https://bugs.launchpad.net/bugs/372532 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
