I’m trying to attach an external monitor to my laptop and mirror duplicate the screen on both screens.
When I have the monitor attached (VGA), the resolution is stuck at 848x480, and if I were to change the resolution, X crashes.
I’ve tried adding a new mode for xrandr,
xrandr --newmode "800x600_60.00" 38.22 800 832 912 1024 600 601 604 622 -HSync +Vsync
xrandr --addmode VGA-0 "800x600_60.00"
xrandr --output VGA-0 --mode 800x600_60.00
but again it crashes if I do this.
Relevant information below:
xrandr -q
