Christopher M. Penalver, what I wanted to point out in my last comment is that since I reported this bug I changed to gnome-shell and even updated to 15.10 so I will not be able to help further debugging this issue and of course as this is about metacity and I don't use it any more I have not seen this bug since then. Of course all new/other xorg related errors have been reported by me in separate new bug tickets as expected.
Would you like me to change the subject of the bug to: "The program 'metacity' received an X Window System error." -- 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/1455916 Title: [Dell Inspiron N5110] Xorg unexpectedly crashed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1455916/+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
