My Screen Setup on Ubuntu

I run a 4K laptop screen and 2 monitors but it seems that there is no good way on Ubuntu 23 to run fractional scaling without apps looking blurry. So I decide to disable Wayland and use X11:

sudo vim /etc/gdm3/custom.conf # Uncomment WaylandEnable=false sudo systemctl restart gdm3

Setup the screens and stop the cursor from flickering:

xrandr --output eDP-1 --auto --scale 1x1 --pos 0x0 \ --output DP-3-5 --auto --scale 2x2 --pos 0x-2160 \ --output DP-3-6 --auto --scale 2x2 --pos 3840x-3000 --rotate left # This black magic stops the cursor from flickering: xrandr --output eDP-1 --auto --scale 0.9999x0.9999
