The path was wrong in #6 (I forgot the /.config/ Copying
/home/<user>/.config/monitors.xml to /var/lib/lightdm/.config/monitors.xml fixes this issue for me (see image attached). Btw.: After upgrade to new HWE/Xorg I had to resize my monitors to get rid of similar situations for the gnome session itself. That could be done by reajusting resolution two times (go for wrong resolution and back to right resolution). But that could be done via GUI (system settings/displax devices). Be that a bug in itself or not, I think it is not convenient, at least. However, the GUI setting did not affect lightdm monitor settings. Only copying monitors.xml to /var/lib/lightdm/.config/ did. For lightdm, I think this is a bug, just because it requires non-GUI user interaction. Average users should not be tricked into such situations. ** Attachment added: "CIMG1107.JPG" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1665853/+attachment/4821679/+files/CIMG1107.JPG -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1665853 Title: Gnome Flashback: Could not assign CRTC to outputs, ignoring configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-flashback/+bug/1665853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
