Ah, thank you very much. It works. I think before I was using wayland thus why it didnt work.
This command did it. xrandr --output eDP-1 --scale 1.25x1.25 --brightness 0.8 Using the scaling option also helped solve the scaling issue I had. However, it showed another bug. When I use this scaling command (no matter if fractional or not), then the mouse can still not move outside the 1x1 area. Meaning that if I scale such as xrandr --output eDP-1 --scale 2x2 then my mouse has only a quarter of the screen left for usage. Should I file another bug report?
