Public bug reported:
I have one monitor only. However, x11 recognises two screens, and places one of
them to the right of my real screen.
This causes several issues: I can "lose" my mouse pointer at the right hand
side of my real screen. Some apps start on the non-existent screen, and it is
hard or impossible (in case of some steam games) to pull them out to my real
screen.
Gnome settings shows the two screens, my real screen first and the non-existent
one second, but does not let me fiddle with the settings of the second one. It
seems that xrandr sees this screen too:
~$ xrandr -q
Screen 0: minimum 8 x 8, current 7680 x 2160, maximum 32767 x 32767
HDMI-0 disconnected (normal left inverted right x axis y axis)

DP-3 disconnected (normal left inverted right x axis y axis)
None-1-1 connected (normal left inverted right x axis y axis)
3840x2160 60.00 +
But trying to remove "None-1-1" yields an error:
~$ xrandr --output None-1-1 --off
X Error of failed request: BadMatch (invalid parameter attributes)

Here is the content of /sys/class/drm, but I don't know what to make of
it.
card0 card1 card1-DP-2 card1-HDMI-A-2 version
card0-Unknown-1 card1-DP-1 card1-HDMI-A-1 renderD128
I use an right-to-left environment, and maybe this is related.
