Maybe this can split into several bug reports, since there could be several causes for the single points.
Personally I can confirm point 3). I will further explain the problem. My setup is a one portrait monitor (1920x1080) and one landscape (1080x1920). My desktop background is 1920x1920 so in zoom & center setting both monitors are filled without the background being zoomed. However after relogin or reboot the secondary landscape monitor's background is either zoomed by 1.7x (1920/1080) or cropped to 1080x1080 leaving black bars left and right, whether the setting was zoom or center. Switching between zoom and center in the setting then returns the original mode. Steps to reproduce: 1. Have two fullhd monitors, primary in portrait, other in landscape mode. 2. Set a 1920x1920 image as desktop background 3. Set center or zoom mode 4. Log out and log in again ** Attachment added: "Screenshots of the two error modes and how it should be" https://bugs.launchpad.net/unity/+bug/1185784/+attachment/4461221/+files/screenshots.tgz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1185784 Title: Multi-monitor configuration with different vertical resolution To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1185784/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
