Steve, thanks for looking into this with 19.04. I wasn't expecting that it would improve things, but I decided that if I was going to pour more effort into this, U would wait for the next OS release.
Yes, the other post may not be directly relevant to our problem, but it's still interesting. I've thought that some underlying change may have been made to disallow a second session manager to run, so this might be a clue as to where to look. I get the same xrandr results as you. % xrandr -q Screen 0: minimum 8 x 8, current 1600 x 1200, maximum 16384 x 16384 DVI-I-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 432mm x 324mm 1600x1200 60.00*+ 1280x1024 85.02 75.02 60.02 1024x768 85.00 75.03 70.07 60.00 800x600 85.06 75.00 72.19 60.32 56.25 640x480 85.01 75.00 72.81 59.94 DVI-I-1 disconnected (normal left inverted right x axis y axis) DP-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) % xrandr -display :0.1 Screen 1: minimum 8 x 8, current 1600 x 1200, maximum 16384 x 16384 DP-3 connected primary 1600x1200+0+0 (normal left inverted right x axis y axis) 432mm x 324mm 1600x1200 60.00*+ 1280x1024 85.02 75.02 60.02 1024x768 85.00 75.03 70.07 60.00 800x600 85.06 75.00 72.19 60.32 56.25 640x480 85.01 75.00 72.81 59.94 Now, can we get developers responsible for different parts of the OS related to display recognition and the launching of xfce4 to please coordinate on this problem and track down the source. It definitely happened due to a change from 18.04 to 18.10, so diffs between those two versions is the place to look. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822181 Title: Ubuntu 18.10 broke dual-screen dual-desktop configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfwm4/+bug/1822181/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
