Change console resolution (Armbian/bookworm)

[jcgraybill]

Hi - I'm running the Armbian "bookworm" cli-only Linux image on my Pinebook, which overall works great, except that text is extremely small on the 1080p LCD display. I've seen other folks with lower-resolution modes for console, but can't figure out how to change it.

I've tried updating disp_mode in /boot/armbianEnv.txt to no avail. No setting I've tried for this has had any effect. I've had slightly more luck adding extraargs=video=1280x720p@60 to this file: the screen goes black during boot, so at least something is getting passed to the kernel, although it seems to be an invalid resolution, and I haven't been able to find a valid one through trial and error.

Does anybody have any ideas? It looks like there are configuration utilities available if you add a desktop environment, but I'd really rather avoid that if possible.

Thank you!

I figured it out! I needed to change the terminal font and font size with:

Code:

sudo dpkg-reconfigure console-setup

The VGA font supports two large sizes (the ones that state they require framebuffer support). 

And then to increase the screen brightness:

Code:

sudo apt install brightnessctl
sudo brightnessctl set 10

With these in place, I now have a pleasantly readable console experience.
