I set desktop scaling to 200%, reboot, and it resets back to 100%.
It's a VirtualBox VM with video type set to VMSVGA.
Any ideas how to fix this problem?
Config info as requested:

  • Not normal behavior. Please add information about your system and your configuration. – vanadium Apr 22 '22 at 18:47
  • @vanadium pretty much all-default installation. The only thing that might be unusual is that it's a VirtualBox machine. I don't know what extra info is needed. – user626528 Apr 22 '22 at 19:46

    Add that information to your question so everybody knows this is relating to a virtual machine. Again, it is not supposed to be so and for many people on real hardware, the setting is remembered. – vanadium Apr 23 '22 at 06:23

This is an initial answer, waiting for your feedback. Please post in the OP the output of the following commands, both when you have 100% and 200% scaling:

$ xrandr
$ gsettings get org.gnome.desktop.interface scaling-factor
$ gsettings get org.gnome.desktop.interface text-scaling-factor
$ gsettings get org.gnome.settings-daemon.plugins.xsettings overrides

Until you do that, here is a suggestion. You could try a combination of actions to arrive at your final result, all applicable via command line/configuration, so they could/should be applied at every reboot, eventually by adding to a suitable login script.

  1. Set scaling via xrandr (--scale, and other adjustments if needed). Whatever xrandr command you use, that can be applied automatically during login. See ref, ref.

  2. Set a suitable Modeline via Xorg. For instance, I have in my /etc/X11/xorg.conf.d/10-monitor.conf

    Section "Monitor"
    Identifier "LVDS-1"
    Modeline "1344x744_60.00" 80.75  1344 1408 1544 1744  744 747 757 773 -hsync +vsync
    Option "PreferredMode" "1344x744_60.00"
EndSection

  3. Use gsettings, like

    $ gsettings set org.gnome.desktop.interface scaling-factor 2
$ gsettings set org.gnome.desktop.interface text-scaling-factor 1.2
$ gsettings set org.gnome.settings-daemon.plugins.xsettings overrides "{'Gdk/WindowScalingFactor': <2>}"

    Note that you may need a trick like this.

  4. A combination thereof, like here.
