Hi Marteen, Even in virtual console it freezes.
Steps I performed. 1) Login to my desktop session 2) Run command "pgrep Xorg" to get the pid. Lets say 1122 3) Then I pressed "control-alt-f2" to go to virtual console. 4) Run command "pgrep Xorg" to get the pid and it was same i.e 1122 5) Run command "sudo gdb /usr/bin/Xorg 2>&1 | tee gdb-Xorg.txt" 6) Inside gdb console I ran "attach 1122" On step it showed it showed some output GNU gdb (Ubuntu/Linaro 7.4-2012.04-0ubuntu2) 7.4-2012.04 Copyright (C) 2012 Free Software Foundation, Inc.

"CTRL-c" was also not working. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/994688 Title: Xorg crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/994688/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
