As previously reported, I've tried a number of different Nvidia and the X.Org drivers with no better results.
And as previously reported: -------------------------------------------------- 54-> xrandr 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 Note: No DP-3? RandR must be numbering the display ports differently from NVIDIA. The above output is identical to what you get with the command: xrandr -display :0.0 However, you can probe the second screen with the command: xrandr -display :0.1 55-> 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 -------------------------------------------------- So, as you can see, RandR DOES know about the second display, but it does not properly integrate it into the system. Since you say that Xfce is built upon RandR, I'd say that that may be the place to start. I don't know what is going on down at this level, but if someone in the developer community thinks this is actually a RandR problem, please change the target package from my guess of xfwm4 to libxrandr2 or whatever you think appropriate. Still, this is a lot of theorizing when someone in the developer group could be testing this out on a dual screen configuration and see what actually happens! -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
