I've been using PinePhone / Mobian for a while now, and all of the sudden my screen is going blank if I'm not constantly engaged with the devices (meaning I have my finger on it). If I look at it for a few seconds without touching it, the screen goes off and I have to touch it for it to come back on, usually. Sometimes it just comes back on.
The reverse is also true: When I hit the power button to turn off the screen, after a few seconds I can see the screen glowing, even though it's a black screen, because the backlight is on.
I've tried disabling the blank screen and suspend options in the settings, but this doesn't do anything. Any idea why this might have happened? The only thing I did today was run
wlr-randr --output DSI-1 --scale 1.5
to change the screen DPi. But even after rebooting, that DPi adjustment goes away but this problem persists.
