OK, there are three problems related to external screens, with these packages installed. Let me know if you want them to be filed separately:
1- after connecting the external monitor (even if it's not turned on or active) some windows are painted incorrectly, with bits of the desktop background or other windows showing through. 2- after setting the display to external-only and using it for a few minutes, it flips back to side-by-side mode. this happens repeatedly. I can use Display Settings to go back to the external monitor but it does not stick. 3- after 2 occurs, fn-f7 no longer seems to have any effect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/749817 Title: natty regression: screen goes black when external monitor is connected -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
