for some reason, after a while the screen connected to my RPI 3B+ goes off, and stays off, until I unplug it and plug it back in again. I only run in console mode, and running alt+F[1-4] does nothing, neither does pressing any key, but unplugging and plugging back in the HDMI is the only sure way to bring it back.
I use an HDMI=>SVGA connector, then connect to an SVGA monitor, and disconnecting at the SVGA side has no effect.
and I've added
but still after a while the screen goes off, and won't come back until I unplug it.
Anyone have any ideas?
