Thanks for the heads up about updating the BIOS, next time I will definitely do that before submitting a report to avoid wasting your time.
However, the problem still occurs (after re-enabling animations in compiz). Here is the output of the desired command: $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date A18 09/24/2013 What happens is that when trying to open a new window, sometimes (not always), X restarts. It's happened when trying to write a new email in Thunderbird and when trying to show the Pidgin window. Let me know if you need me to run the diagnostics tool again (although the BIOS was the only thing updated since it was run). ** Changed in: xorg (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1511512 Title: Xorg crashes when opening new windows with Intel video card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1511512/+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
