SDDM not working well for rotated monitors in mutli-monitor setup

[NichtSylph]

Hi,

I've been trying to disable my other monitors but the main one for the login, since they are rotated the background image and login area doesn't look well. I tried editing the Xsetup file and added the commands:

xrandr --output DP-2 --off
xrandr --output DP-1 --off
xrandr --output HDMI-A-1 --off

however, only the DP-2 shuts off, the rest do not. I'd like to have all three of those off.
