I’m using a dual monitor setup and the login screen is always active on the secondary screen at startup … It only affects SDDM so the wrong screen is offered for login.
With X11, this issue could be fixed using xrandr …
Is there any similar solution when using wayland?
$ xrandr | grep ' connected'
HDMI-A-2 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 531mm x 299mm
HDMI-A-3 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 531mm x 299mm
It might make better sense to re-build everything that can be built against wlroots to encourage a more even playing field; granted, there are logistical considerations.
I suppose, despite the general hype, that might be detrimental to the walled garden KDE seem focused on creating.
$ kscreen-doctor -h
Usage: kscreen-doctor [options] [output.<name>.<setting> output.<name>.setting [...]]
kscreen-doctor allows to change the screen setup from the command-line.
Setting the output configuration is done in an atomic fashion, all settings
are applied in a single command.
kscreen-doctor can be used to enable and disable outputs, to position screens,
change resolution (mode setting), etc.. You should put all your options into
a single invocation of kscreen-doctor, so they can all be applied at once.
Usage examples:
Show output information:
$ kscreen-doctor -o
Output: 1 eDP-1 enabled connected Panel Modes: Modes: 1:800x600@60 [...] Geometry: 0,0 1280x800
Output: 70 HDMI-2 enabled connected HDMI Modes: 1:800x600@60 [...] Geometry: 1280,0 1920x1080
Disable the hdmi output, enable the laptop panel and set it to a specific mode
$ kscreen-doctor output.HDMI-2.disable output.eDP-1.mode.1 output.eDP-1.enable
Position the hdmi monitor on the right of the laptop panel
$ kscreen-doctor output.HDMI-2.position.1280,0 output.eDP-1.position.0,0
Set resolution mode
$ kscreen-doctor output.HDMI-2.mode.1920x1080@60

output.eDP-1.position.1280,0
Multiple settings are passed in order to have
kscreen-doctor apply these settings in one go.
