As the title, my login background is split into 2 (1 horizontal and 1 vertical) while I'm on the login screen. Are there any solutions to temporarily disable the vertical monitor and then re-enable it after logging in?
I check the vertical with xrandr and it seems it is the DP-2

I tried to disable it with xrandr --output DP-2 --auto but it did not work.
