Hi,
I’ve bought a Togtratric 8.8" Widescreen display for my Volumio project. After a lot of searching, testing and head scratching I’m struggling to get it working. At boot I see the Volumio logo and text in the middle of the screen, then the screen goes blank. There’s a brief white flash and then nothing. It’s connected via HDMI and with it’s own power source.
I’ve posted my userconfig.txt (with elements I’ve tried and then commented out) and xorg.0.log below. Does anyone have any ideas?
