OK, progress of sorts. If I log in using Ubuntu Classic (no effects), then plugging in the external monitors WORKS! I get an extended workspace.
However, previoiusly I used to use the Dell key (Fn-F8) to switch modes such that I had the external monitor only and the laptop display would be turned off. If I try that now, the external monitor displays a "signal out of range" error, and if I press the key a couple more times to get back to the laptop, the display comes back but scrolls horizontally at a pace too fast to see what's on the screen. So there's some difference in the Ubuntu Classic options that is causing the main corruption problem. Perhaps this bug needs to be assigned to a different package other than the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/850763 Title: [Intel 945GM/GMS] Plugging in external display results in garbled screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/850763/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
