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 Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
