I tried to get my external screen on zoom level 100% while my laptop screen needed to stay on 200%. I must have done something wrong, because now only my external screen is working.
xrandr -q
Screen 0: minimum 8 x 8, current 6400 x 2160, maximum 32767 x 32767

3840x2160 60.02 +
DP-3 disconnected (normal left inverted right x axis y axis)
DP-4 disconnected (normal left inverted right x axis y axis)
The DP-2 is my lap-top screen. When I try to set my laptop screen to auto, I get an error:
xrandr --output DP-2 --auto
xrandr: Configure crtc 1 failed
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 21 (RRSetCrtcConfig)
Value in failed request: 0x0
Serial number of failed request: 47
Current serial number in output stream: 47
Listing the monitors only shows my external screen:
xrandr --listmonitors
Monitors: 1
0: +DP-0 2560/597x2131/336+3840+29 DP-0
I would be happy if I got things back to normal. Please keep in mind that I am not very experienced with Linux.
