SDDM on multiple monitors, duplicated display, incorrect layout and incorrect focus issues:
Hello, I’m (somewhat) new to Linux and whatnot. I’m on KDE Plasma and after trying some tinkering, I can’t seem to make it so that the login screen appears only on my primary monitor and not both of them. Along with that, the login screen also focuses the the wrong monitor. I’m really not sure what I’m doing wrong, as both people online and the guide in the arch wiki gave examples of what to do to fix this. My file pretty much looks like this:
#!/bin/sh
# Xsetup - run as root before the login dialog appears
xrandr --output DP-2 --off
Which is what I was instructed to do in the Discord.
However, this doesn’t seem to work for some odd reason. So, along with that, I also tried doing this from here to get the correct display ports by logging in to X11:
https://www.reddit.com/r/archlinux/comments/143b6we/comment/jn8zya3/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
That also didn’t seem to work. The iterations I tried to see if anything would change at all were (might not be exactly what it said but you’ll get the gist): DP-0, DP- 1, DP-2, DisplayPort 0, DisplayPort 1, and DisplayPort 2.
Because that didn’t seem to work, I also tried what was shown in the arch wiki:
https://wiki.archlinux.org/title/SDDM#Match_Plasma_display_configuration
# cp ~/.config/kwinoutputconfig.json /var/lib/sddm/.config/
# chown sddm:sddm /var/lib/sddm/.config/kwinoutputconfig.json
These are the contents of that file, which I can’t really seem to figure out:

As a last ditch effort, I tried the solution provided here:
Along with those fixes, I tried some other things as well, such as:
- Applying Plasma Settings (didn’t change anything as far as I can tell)
- Turning off one monitor and THEN trying applying plasma settings (which also didn’t)
- Changing brightness in xrandr, but, from what I’ve seen nothing happens when I try to change anything in that file.
Overall, I’m just kind of at a loss for what I should do. If anyone could help, I’d appreciate it.
Also, here’s my inxi:
