I'm running Armbian Jammy (23.02.2) aarch64, Xfce 4.16, Kernel: 5.15.93-rockchip64 on a Libre Renegade and would like to change the resolution to 1360x768. I have tried the Display Settings which only has 1280x720 and I can't change the scale, also I have tried changing the values in Settings Editor but that doesn't change anything.  (DISPLAY=:0 xrandr -q) shows: xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1280 x 720, current 1280 x 720, maximum 1280 x 720
default connected 1280x720+0+0 0mm x 0mm
   1280x720       0.00* 

 

I have limited experience with XFCE and terminal commands, any help is appreciated thanks.

Tried something like this in armbianEnv.txt?

 

extraargs=video=HDMI-A-1:720x480@60

 

Sorry if this is not the correct way to reply I don't see a reply button. Nope I haven't even heard of this, I'm assuming A-1 refers to the monitor? Where can I find this file?

I found the file I will give this a try.

I tried this and just changed the screen resolution in the example you gave, now I have no video output. Is there a way to change the file outside of Armbian?

I put this into a Pi 4 and can see the file.

I changed owner of the file and edited it with nano, changed it from "extraargs=video=HDMI-A-1:720x480@60" to extraargs=video=HDMI-0:1360x768@60 and got picture back but it's still not scaled correctly, I will keep playing with this.
