SDDM / login scaling broken after 2022-01-02 update

SDDM / login scaling broken after 2022-01-02 update

SDDM is no longer respecting my DPI settings since the latest update. I absolutely spammed my conf files to get the scaling working prior to the update, so I’m not sure what to try now.

  • The “Sync” button in the KDE SDDM configuration GUI does nothing
  • The same SDDM theme was correctly scaled prior to the update
  • Other themes also do not scale properly when I try them

What can I do to fix SDDM scaling?

try appending xrandr --dpi (value of the dpi) in /usr/share/sddm/scripts/Xsetup as root. have a look here if that doesn’t work :point_down:

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

Thanks for your help. Unfortunately, there is still no effect on the SDDM scaling. This is what I have tried so far:

  • Appended xrandr --dpi 192 to /usr/share/sddm/scripts/Xsetup as root
  • Set EnableHiDPI to false in /etc/sddm.conf, and /etc/sddm.conf/hidpi.conf
  • Created a new conf file (SDDM - ArchWiki): /etc/X11/xorg.conf.d/90-monitor.conf
    Content:
Section "Monitor"
        Identifier      "eDP-1"
        DisplaySize     344 194 # in millimeters
EndSection

  • Re-enabled EnableHiDPI

try changing values in /usr/lib/sddm/sddm.conf.d/default.conf :crossed_fingers:

No dice, I’m afraid. I wonder if it has anything to do with this in my inxi output? Should these match?
