#!/bin/bash

xrandr --output HDMI-1 --primary --left-of eDP-1 # change primary display to monitor, instead of the notebook's display
gsettings set org.gnome.desktop.peripherals.mouse accel-profile 'flat' # remove mouse acceleration from gnome to respect mouse DPI
sleep 3 #just to give "time" for the things

##### Other script/file
#overwatch-post-script.sh 
#!/bin/bash
