I’ve recently been using a wide screen (3440x1440) at work, and I’m thinking of getting one at home. The problem I run into is that having a large screen becomes inconvenient when sharing a screen with colleagues. Sharing a single window often isn’t an acceptable workaround, because often I need to switch between multiple applications.
It looks like this should be possible using xrandr, but while I am able to run the appropriate commands with out errors, it has no effect on the screen.
Given this initial configuration:
Screen 0: minimum 320 x 200, current 3440 x 1440, maximum 16384 x 16384
DP-1 connected primary 3440x1440+0+0 (normal left inverted right x axis y axis) 798mm x 334mm
3440x1440 59.97*+
2560x1440 59.95
1920x1080 60.00 50.00 59.94
1680x1050 59.95
1600x900 60.00
1280x1024 75.02 60.02
1440x900 59.89
1280x800 59.81
1152x864 75.00
1280x720 60.00 50.00 59.94
1024x768 75.03 70.07 60.00
832x624 74.55
800x600 72.19 75.00 60.32 56.25
720x576 50.00
720x480 60.00 59.94
640x480 75.00 72.81 66.67 60.00 59.94
720x400 70.08
I ran:
$ xrandr --setmonitor DP-1-1 1720/399x1440/334+0+0 DP-1
$ xrandr --setmonitor DP-1-2 1720/399x1440/334+1720+0 none
There are no errors, but nothing happens. This is running with Xorg;
I’ve tried the same thing with Wayland (where DP-1 in the above
becomes XWAYLAND0).
Is there any way to make this work?
