Please someone help I can't start X11... I installed: sudo apt install xserver-xorg-video-fbdev openbox x11-xserver-utils xinit xserver-xorg-input-evdev Created this /etc/X11/xorg.conf.d/99-fbdev.conf file And tried sudo startx, then the LCD got a black screen for a fraction of a second, and I got (in my ssh session) The error message is FBIOPUT_VSCREENINFO: Invalid argument I also see that xorg wants to use 24 bit color, but my LCD is 18 bit color. I will try to get X11 working again with the linux 6.13 build folders that worked for me in april

Happy to report that with a different wiring, I got the touch part working... it served me well to follow examples from the Raspberry forum The mipi command string is the same as the one kungfupancake github, but removing the 0x21 command. The bin file should be copied into /lib/firmware/panel-mipi-dbi-spi.bin I used the vanilla armbian image with kernel 6.12.30 (not using my custom build method of removing the arm64-dts-sun50i-h618-orangepi-zero2w-Add-missing-nodes.patch ) It works with all the 3.5" and 4.0" red LCDs I have (some 3.5" LCDs I have are ili9486).

Here are a few generic tips to consider: - Going to something industrial grade is always good. mean-well would be entry-level here - Phone chargers are not good for powering SBCs. They're designed to handle constant load while SBCs draw is variable depending on load. - Usually SBCs prefer slight overvoltage. So it is usually not an issue to feed them with an PSU that outputs 5.1 or 5.2 volts since this compensates for losses across wires, connectors and the PCB anyway. I personally have a mean well HRP-200-5 which powers all my sbcs but would be way too much for a single one. Official chargers from Raspberry or Orangepi would do too since they already come with slight overvoltage by design.

Thank you - A new, better PSU would be an inexpensive and easy fix. But being so new to this, I am only guessing which one to buy. Can you please recommend one? For example, which one do you use? I appreciate your help very much.
