Multihead and sddm, trying to rotate and assign primary monitor.

Hi there. I have read through a number of wiki pages, followed more than a few online tutorials... But, for the life of me, I cannot get sddm and xrandr playing properly together.

I have two(2) a monitor setup looks like this...

         ┌─────┐
         │     │
┌────────┤     │
│        │     │
└────────┤     │
         │     │
         └─────┘

Both monitors are 1080p, connected via DisplayPort, on my nVidia GTX1660 ti... with the left one as primary. The right monitor is rotated 90° anti-clockwise. Once into KDE, and KScreen kicks in, the moitors are set up properly. No matter what I put xrandr commands I put into /usr/share/sddm/scripts/Xsetup, it never sets the primary monitor correctly, nor does it rotate the right hand monitor.

This is the output of xrandr after I have booted...

Here are the contents of the /usr/share/sddm/scripts/Xsetup file, and /etcsddm/conf...

#!/bin/sh
# Xsetup - run as root before the login dialog appears

xrandr --output DP-1 --primary --mode 1920x1080 --pos 0x420 --rate 75.00
xrandr --output DP-5 --mode 1080x1920 --pos 1920x0 --rate 75.00 --rotate right

[XDisplay]
# Xsetup script path
# A script to execute when starting the display server

DisplayCommand=/usr/share/sddm/scripts/Xsetup

Everything I have read tells me this should work. It hasn't. I'm obviously doing something wrong that I can't see. Any and all advice is appreciated.

Re: Multihead and sddm, trying to rotate and assign primary monitor.

Is the script executable? Add a  logging line to check whether it's executed at all e.g.

 date > /tmp/sddmXsetup
