Armbian build: Armbian_23.8.1_Bananapim2zero_bookworm_current_6.1.47 Hardware: BananaPi M2 Zero I am using pure CLI environment, and when the output is on screen I can't really tell what is the resolution or the refresh, but the monitor is 1080p@60 and it seems to be matching. Although when I run apps that use SDL2 for example; the resolution is changed, and I tried to set a fixed resolution but there seems to be no way to do so in Armbian. I changed the boot settings and those are correctly set with 1080p@60; then I tried to use xrandr (I have X11 installed as I have SDL2 installed too), and it says "can't open display" (I assume because I have no X app running?); so I am basically stuck at this point. Is there a global setting that force the OS to a specific resolution? Is my CLI running really at 1080p@60? How can I tell an app running in X server to set itself to the same resolution of the current CLI? Thanks

After trying different distro for the BPI M2 Zero, I installed Armbian, and it works great with a standard 16:9 screen. Now I would like to use a bar LCD (Waveshare 7.9 inches); but the setup instructions are for RPI, not for Armbian, so I am not sure how you set up a screen that is not default (And I exclude that I can just plug in the screen and it will magically work. I am not using X interface since the BPI is quite slow, so I am in terminal. Thanks
