How can I reset the desktop mode screen resolution?

Submitted ⁨⁨11⁩ ⁨months⁩ ago⁩ by ⁨petrescatraian@libranet.de⁩ to ⁨steamdeck@sopuli.xyz⁩

I was playing around with AnyDesk on the Deck, getting some stuff, and I wanted to set the screen share resolution to fit my laptop screen (where I was streaming the screen to). I somehow managed to change the resolution to something really small, and no setting on AnyDesk could change it back.

I opened the menu but could not get to the settings, so I thought a restart should fix it. Of course, I lost connection to AnyDesk, and now, whenever I access the desktop mode, I am greeted by a blank screen after the splash screen. I suspect the desktop mode is still loaded, but as the screen resolution is messed up, nothing is shown on the screen.

Is there any way to change it back to the default?

I don't have a complete solution, but I do have some ideas:

Have you tried hooking it up to an external monitor? Sometimes auto-config can help you recover from weird states if you plug in a different display.

On my Deck, I can reach a terminal by using CTRL-ALT-F4 that is separate from the main desktop mode (CTRL-ALT-F1 switches back). Default user seems to be called "deck". You may need to set a password to use sudo. I am not sure exactly how the desktop environment is set up on the Deck so I am not sure exactly what you need to change or where the files would be -- maybe check under /usr/share/X11/xorg.conf.d to see if anything is set to an insane value there?

You might try sending Valve a support request

As a last resort, you could try a factory reset. You'll nuke everything else on it too though...

  Once in a terminal, this command should change the resolution
  
  xrandr --output eDP --mode 800x1280

    @SatyrSack @e0qdk Thanks. I, unfortunately, do not have a dock. I will go to a friend tomorrow who has and I will be connecting it to a monitor. Hopefully this will help.
