I am using Ubuntu 11.04 Natty on Lenove Thinkpad T400. The video chip is Intel GM45. I have the same problem when connect to external monitor. And since I need to move between workplace and meeting rooms frequently, it becomes even bad for me.

But anyway, the external monitors as well as barcos in our meeting rooms worked fine with Ubuntu 10.10 Maverick -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753971 Title: Display garbled upon restoring original resolution or connecting external displays -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
