I recently switched from Gentoo to Void Linux and installed it on a system with one monitor.
But now I have switched locations and use a two monitor system. On my Gentoo installation, everything worked and X11 recognized that the two screens should not be merged together, but rather, should be distinct screens.
Here is the output of XRandR:

The issue, at least it seems to me, is that it extends HDMI-A-0 (1920x1080+1920+0). This fear is confirmed if I use ghc to get all of the Screens, which X11 provides to applications.
The output of the command
ghc -e "Graphics.X11.openDisplay [] >>= Graphics.X11.Xinerama.getScreenInfo"
is the following:
[Rectangle {rect_x = 0, rect_y = 0, rect_width = 3840, rect_height = 1080}]
Just to clarify, what I want is that X11 provides two screens (each 1920x1080) instead of one long screen (3840x1080)
I have tried to find answers online, including the following commands. None of them worked
xrandr --output HDMI-A-0 --primary --mode 1920x1080 --pos 0x0 --rotate normal --scale 1x1 --size 1920x1080+0+0 \
--output DisplayPort-0 --mode 1920x1080 --left-of HDMI-A-0 --rotate normal --scale 1x1 --size 1920x1080+0+0 ;
xrandr --output DisplayPort-0 --auto --mode 1920x1080 --left-of HDMI-A-0 --pos 1920x0
xrandr --output DisplayPort-0 --auto --mode 1920x1080 --left-of HDMI-A-0 --pos 0x0
xrandr --output DisplayPort-0 --auto --mode 1920x1080 --left-of HDMI-A-0
And so on..
Thanks for any help
ghc
call but Xmonad also thinks I have one large screen instead of two. My guess is that I changed or missed some dependent system libraries that are used by Xmonad. Did you find a solution?
