I have some problem to rotate my screen, I want to use batocera in vertical mode.
I don't find the command xrandr ?
in config.txt works but the comeback from emulator makes an issue (black screen)
I read some doc on xrandr perhaps i need to use this command ? but I don't find it ?
Somebody succeed in a vertical mode (batocera 5.24 on rpi3 linux 4) ?
