Actually, I guess it's not even non-rectangular configurations that cause this issue - after changing them to a wide rectangular configuration, DVI-1 still displays the region from 1280x1024+0+0 (which is now also displayed on the topmost screen), while xrandr still claims it's 1920x1080+2560+0. The cursor isn't huge anymore though. So this just seems to be some issue with handling multi-monitor configurations. Again the cursor moves across all screens correctly, but the windows don't.
Also another correction, the previous version I was using was 12.10, not 12.04. Both configurations worked fine there. (Except that Awesome WM would place windows off screen, but that's another bug...) I tried running xcompmgr to see if that would make any difference, but there's no change. ** Summary changed: - With nonrectangular multi-monitor arrangements, display region is wrong + [HD5770] Multi-monitor display region is wrong (worked in 12.10) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1184063 Title: [HD5770] Multi-monitor display region is wrong (worked in 12.10) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1184063/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
