Lower the login screen resolution

Hi All,

New to the forum, does anyone know how to lower the resolutiin for the login screen(ssdm) ? Attach is the screen shot, i am not able to see fully the deaktop options.

just use chat gpt and i did the following

  1. create the following sudo nano /etc/X11/xorg.conf.d/10-monitor.conf if not exists and add the following

—begin—

Section “Monitor”
Identifier “Monitor0”
Option “PreferredMode” “1280x720”
EndSection

Section “Screen”
Identifier “Screen0”
Monitor “Monitor0”
DefaultDepth 24
SubSection “Display”
Modes “1280x720”
EndSubSection
EndSection

–end----

  1. add this to video=1280x720 to GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash video=1280x720”.

Oh, my Lord. That should not work. And if it does it will only work with X11. Where the world ( incl. KDE ) is moving to Wayland.

Check whether sddm.service is running. And check /etc/sddm.conf.d

hi,

it is now running but my /etc/sddm.conf.d/ directory is empty

systemctl status sddm.service

Here is what I have in there:

The example Wayland settings do not work, even when i just set DisplayServer=wayland only. Thank you.

What is the resoltion of the screen?

it is 1360x768, when i try your wayland config i have a high pitch sound.

Video=1280x720 only sticks to the console (vtty) screens, ignored by all GUIs, except with some Intel GPUs using display driver provided by xf86-video-intel.

thank you for info

Try adding

EnableHiDpi=false

to the kde_settings.conf file in the [General] section. Then reboot

i think i have did it earlier but i am not able to set it.

done, but it is under the [X11] from the man.

How? You have to imagine that we cannot see what you are doing. So, please show that here.
Another thing: since you have Plasma6, betting on X11 is betting on a dead horse. From Dec this year, Plasma6 will use Wayland and no longer X11. Create the 2 files I told you about above. But change this line

CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1

to

CompositorCommand=kwin_wayland --width=1360 --height=768 --scale=1 --drm --no-lockscreen --no-global-shortcuts --locale1

and reboot.

I really have to do what i have now, i have until December this year to use tumbleweed with plasma6 : )

When i made the changes it fails to boot into the login screen but boots into the console instead. Below is the working current configuration. the compositor i put a hashtag but it formatted the text, so i just clear it out.

cat /etc/sddm.conf

[General]
DisplayServer=x11
Numlock=on

[X11]
ServerArguments=-nolisten tcp
EnableHiDPI=false

[Wayland]
