Change kde sddm login resolution on 4k laptop screen


I am trying to configure my fedora37-kde laptop ( thinkpad T15 gen2 ) with a 4k screen. when I start my laptop the kde login is very small. Do someone know how I can scale the screen to make it readable ?

I have tried some stuff but still without success:
on /etc/sddm.conf

# Enable Qt's automatic high-DPI scaling

but also tried on the sections [X11] and [Wayland]

Can someone help me ?

thanks in advance,


In system-settings in the SDDM section there should be a button at the bottom for “Apply plasma settings” which should copy your plasma scaling to sddm.


I have tried but doesn’t change the resolution of my start screen. thanks anyway ! :wink:

kind regards,
