Login screen for KDE - dual monitor

Help
1

I have a possible bug to report:

On the KDE login screen on a dual monitor system, the login dialog appears on both monitors (as does the background) but typing only populates one of the dialogs. It all still functions (it logs me in) but I think only the dialog receiving the typed text should be displayed.

I was going to send this in via bugs, but I couldn’t find an appropriate category to file it under.

Report this for sddm.

As long as the typing not populates all (most times three in my case) i never thought about that as a bug. Okay.

Until i first applied (transferred) my KDE display settings to SDDM (on 6.0) my external monitors stayed blank and the login dialog (and background) only appeared at the internal Notebook screen btw.

I would rather like the typing completely hidden, instead of that big dots, like in the old (tty login) Days :smiling_face_with_tear: .

For Wayland:
https://wiki.archlinux.org/title/SDDM#Match_Plasma_display_configuration
Change “enabled” to false for the monitor you want off.

{
  "enabled": true,
  "outputIndex": 0,
  "position": {
      "x": 0,
      "y": 0
  },
  "priority": 1
},

For X11: SDDM - ArchWiki

Example, change DP-0 to the one you want, check by running xrandr in X11 (not Wayland).

xrandr --output DP-0 --off
