Tested with kernel 3.1.0-999-201110200416 for amd64. Behaves almost exactly the same as current oneiric kernel, 3.0.0.12#20. I have two displays, main (Apple iMac monitor, res 1920x1080) and ext (an LG1710B, res 1280x1024).
Further information on tests performed: Test1: Boot on latest kernel with only main display connected. Set to suspend. Wait one minute and press power button to resume. System starts (can hear disk). Black screen. Connect ext and power it on. ext stays black. (this seems different - test of earlier kernel showed login here, but this may have been due to Display setting when suspending. I will repeat the test of kernel 3.0.0.12#20 and post here if anything found) Power off reboot needed. Test2: Boot with both displays plugged in and live. The login screen appears on ext only. After login the main screen lights with ubuntu desktop and ext goes black. 'Displays...' shows main set to ON and ext OFF. Set ext to ON and Apply. The output switches to ext and main goes black (main is still set to ON). ext is given the resolution of main, i.e. 1920x1080 so change display setting confirm window is inaccessible, off screen. Window times out and both screens go black. Power-off reboot required. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/863969 Title: ubuntu 11.10b2 resumes on wrong iMac display port To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/863969/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
