As the title says. Installed Batocera 35 on an RK2020, everything seems fine, no issues anywhere. Went looking for the volume hotkeys, since the hardware has no vol. control. Found out that L2 increases volume, but in an attempt to figure out which key brings it back down (apparently there isn’t one) I ended up tapping R2 several times, decreasing the brightness until screen off. Neat feature. Then I tried to raise it back up again and the story ends there.
I’ve reset the machine and it remembers the settings, I’ve tried every possible combination I can think of and I can’t get the screen back on. I’m not sure if brightness can be set via SD card config.txt or whatnot, but I can’t seem to WIFI back into it blind and it’s not auto-connecting.
Short of reflashing the entire card, I’m not sure what to do. In the event of a solution, I’d also like a method for disabling screen brightness hotkeys entirely so this doesn’t happen again.
