I have the same problem on a Dell Inspiron 1545 laptop. It occasionally did that on 11.10, but since the 12.04 upgrade, it does it virtually every time.
Note that this week I installed 12.04 from scratch to see if it improves it, but the situation is still the same. The only workaround I have found is to power off before connecting/disconnecting an external display. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1011994 Title: Connecting / disconnecting DisplayPort often causes crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1011994/+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
