I have two differently sized displays side-to-side, like this:
I would like to shrink the part of one display so that it has a black bar on the left (i.e. part of the physical screen is not used), like this:
Here's my output of xrandr:
$ xrandr Screen 0: minimum 320 x 200, current 3520 x 1200, maximum 32767 x 32767 LVDS1 connected 1600x900+0+300 (normal left inverted right x axis y axis) 309mm x 174mm 1600x900 60.0*+ 1440x900 59.9 1360x768 59.8 60.0 1152x864 60.0 DP1 connected primary 1920x1200+1600+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 60.0*+ 1920x1080 60.0 + 1600x1200 60.0 1680x1050 60.0 VIRTUAL1 disconnected (normal left inverted right x axis y axis)
What I already have
xrandr --fb 3360x1200 --output LVDS1 --mode 1440x900 --pos 0x300 --output DP1 --mode 1920x1200 --pos 1440x0
Which results in this:
As you can see, the problem is that the displayed area is centered on the screen, while I want it to be aligned right. Also, it only worked with 1440x900 resolution while I want 1200x900.
