RenegadePriest Posted June 6, 2020 Posted June 6, 2020 (edited) I am in the middle of porting a proof of concept app from Raspberry Pi/Raspbian to its (hopefully) permanent home on Orange Pi PC/Armbian, and I am really loving the new environment. Now I need to get my non-standard HDMI display working. It's a 800x800 circular display from China that works fine on my Raspberry Pi once I figured out what the HDMI timings were (they weren't even on the data sheet!). As I learned when configuring the RPi the display does not report its resolution correctly, so it won't work out of the box, but in Raspbian you have the option to force the system to use your custom configuration defined in the config.txt file. I have looked at https://docs.armbian.com/Hardware_Allwinner/#how-to-reconfigure-video-output but I'm not seeing how to add the custom HDMI timings. I'm not sure how it could possibly work without it. Is there a series of steps I can take to force Armbian to look at my custom-defined display rules? Edited June 6, 2020 by RenegadePriest
RenegadePriest Posted June 6, 2020 Author Posted June 6, 2020 No I have not, but I will now I will report my findings, thanks for the info.

Using xrandr I was able to rotate the display, and then updated my xorg.conf to set it permanently. Edited June 8, 2020 by RenegadePriest 1
