Too high resolution on login screen

[fat32 (Jhon Q)]

I am using Fedora 38 with the GNOME desktop environment and Wayland display server, and I have activated fractional scaling using the command gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"'.

I have set a scaling factor of 150% for my display, as 100% is too small and 200% is too large. While everything is relatively fine, I have noticed that when I reboot my computer, the login screen has a very high resolution as if it’s set to 100%. The resolution only becomes correct after I log in. If I lock my computer, the resolution is fine as well.

Is it possible to scale the login screen to 150%, or if not, can I set it to 200%?"

You may want to set up some default settings for GDM, GDM - ArchWiki

I had to do something similar for the login screen to be on the right monitor.

Thank you for your answer!

I’ve seen this example before but, as far as I understand, I need to find monitor.xml file.

Seems I don’t have it.

There’s not one in your user directory, ~/.config/monitors.xml ?

It should look something like:

<monitors version="2">
  <configuration>
    <logicalmonitor>
      <x>0</x>
      <y>0</y>
      <scale>1.5</scale>
      <primary>yes</primary>
      <monitor>
        <monitorspec>
          <connector>eDP-1</connector>
          <vendor>CTO</vendor>
          <product>0x1416</product>
          <serial>0x00000000</serial>
        </monitorspec>
        <mode>
          <width>1920</width>
          <height>1200</height>
          <rate>60.003</rate>
        </mode>
      </monitor>
    </logicalmonitor>
  </configuration>
</monitors>

I don’t think so. You can see my find output.
Here is another screenshot from .config directory.
Let me know if I do something wrong.

Making a change in gnome-settings → Display should cause that to show up.

[fat32 (Jhon Q)]

You are right! It’s appeared.

And the initial problem is solved!!!

Unfortunately, I’m not sure whether the fix was due to the new file itself or the command I found and executed from the link you provided.
I did not edit the file.

sudo -u gdm dbus-launch gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"

Thank you so much!
I am happy! =)

This seems to have done it for me as well - I am using 1.5 fractional scaling on a Framework 13, for reference.

I use many usernames and find that making the configuration apply to the system helpful.
