Set normal display resolution
I'm setting up Trisquel on a school laptop. The only problem is display resolution. I have 800x600 on normal boot. *Note: If I enter UEFI at first and exit it booting Trisquel, then I get the normal resolution (1920x1080). There is 800x600 after reboot again.* Please help me set 1920x1080 permanently.
I've played around xrandr, but achieved nothing.

Hello,
Can you please share the model of the laptop computer ?
Laptop: DEPO

Your laptop has a Ryzen APU, you won't get display output to work properly because it requires amdgpu to work, which is proprietary.
Well, it works, as I've noted before:
"Note: If I enter UEFI at first and exit it booting Trisquel, then I get the normal resolution (1920x1080). There is 800x600 after reboot again."
Also I have 2560x1440 on my own laptop with Ryzen APU, running Trisquel.
It's giving you issues which is telling me something's broken, any commonly known GPU released in the last eight years must run proprietary software loaded by the kernel for them to work, partially or fully, Intel is somehow the exception.
If you're getting the X11 or Wayland server to start at all then it likely runs with software rendering, which means worse performance and battery life, but the most expected behavior is to fail to start the display server and throw you back into tty.
Don't expect these GPUs to work with Linux-libre, manufacturers go out of their way to ensure these misbehave with free GNU/Linux distributions.
Understand you, but I am sure, this result can be achieved permanently, isn't it?
After-uefi-boot:
(xvidtune -show):
"1920x1080" 207.38 1920 1952 2192 2432 1080 1084 1088 1104 -hsync -vsync -csync
P.S. I could say the teacher, they should hit F2+ESC+ENTER every time they boot (and I would certainly do that, freedom is worth the inconvenience), but they (windows, ibad useds) would say I am crazy, most important - I am sure this can be fixed. We should try xrandr again.
You could run lspci in each situation you mentioned:
$ lspci -k | grep -EA3 'VGA|3D|Display'
That may give you some further hints about what is happening.
