How to change resolution on login screen

Issues & Assistance
1

Hello.

I am trying to change resolution on login screen when my laptop boots up, but cannot find any info about that.

I have a 4K screen and set resolution to 1920x1080 (fullhd). It works fine when I am logged in and it also works when my laptop wakes up from sleep mode, but on startup it still changes to 4K and everything is so small I can not read it.

Did anyone experience the same problem? How did you fix it?

That is sddm. Have you tried enabling hidpi?

https://wiki.archlinux.org/title/SDDM#Enable_HiDPI

3

Tried it now, did not work.

4

What about an Xsetup script like here:

For sure, you’ll always use mon1 (should be mon1= eDP-1), you could even simplify the script, anyway, maybe the xrandr --auto could help…

5

Did you already try doing the Apply Plasma Settings from Startup and Shutdown -> Login Screen (SDDM)?

6

Tried and did not work, just deleted background and set it to solid white color for some reason. Resolution stayed the same.

7

Also tried this, but without success. Not sure if correctly, because it is a bit too complex for my skills :sweat_smile:

8

Do you want to change the resolution ONLY for SDDM or also after you are logged in?

9

Only for SDDM. When I log in it is already in Full HD, which I want also on login screen after boot.

10

I don't know if this will work for you, since I did this on a desktop - I have a 4k screen and SDDM was tiny - I followed the tutorial on the link below and I was able to get the sddm resolution to 1440p. I had to read it twice to understand what I had to do.

It looks like you can specify your screen size in a Xorg configuration file: SDDM - ArchWiki

I honestly have no idea how that translates in terms of resolution; you might have to experiment to find a useful setting.
