I noticed a vital clue which I missed before. My mouse is responsive, but no clicks are registered (as if I never clicked), I can move the mouse around the screen. The keyboard is unresponsive apart from sys-req. I did not think to check the caps lock led. I will do this next time the crash happens.
Here is what I think is a full backtrace (I don't really know what one of these should look like). I followed the instructions at https://wiki.ubuntu.com/X/Backtracing). I found Xorg's pid then started gdb, attached to xorg's pid and run the gdb command "backtrace full". I hope this helps. If not then please let me know how I can help more. ** Attachment added: "A full backtrace of Xorg, I think" http://launchpadlibrarian.net/30502766/gdb-Xorg.txt -- X crashes and system is only responsive via sys-req on keyboard https://bugs.launchpad.net/bugs/412907 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
