I’m using EndeavourOS (Arch btw) with KDE plasma 6.x (Wayland), SDDM, and systemd as boot manager. I have 2 displays, one HDMI-A-1 (1080p) and one on DP-1 (Ultrawide).

When I boot the password entry cursor defaults to the HDMI display, but I want it to default to the DP-1 display.

I’ve tried a few things, mostly suggestions from ChatGPT. But nothing has worked. The weird thing is at boot the boot menu and boot messages all appear on DP-1, and it is set as primary in KDE and that works fine as well. It is just the logon prompt that defaults to the wrong display.

Things I’ve tried so far.

  • Adding video=DP-1:e to the options in the systemd entry - (No effect)
  • Edited /etc/sddm.conf.d/wayland.conf to run a script that did the following: kwriteconfig6 --file startkderc --group General --key PrimaryScreen DP-1 (didn’t fix it, actually broke the logon process so had to remove it)

I’m just not familiar enough with how SDDM works so hoping for some good pointers to provide the answer or point me in the right direction.

    SDDM seems to be severely underdeveloped. It doesn’t seem to get nearly as much love as the rest of KDE. You might consider switching to GDM or another display manager that does what you want. You can be happy that your HDMI monitor is not mirrored smaller on your ultrawide.
