I've been having a rather odd issue with an entirely pink screen upon cold boot.
I tried with Raspbian and it didn't occur there.
This has actually prevented me from using the device at all now.
When I first set it up, I was able to Ctrl C the setup stuff and type in reboot. When it rebooted, I was able to use it again.
However, last night the Wifi completely died. I tried everything to revive it but it kept asking for the password repeatedly. Tried different networks, no luck.
Figured power cycling might help. Bad idea.
Now I can't SSH in to type in reboot, and I'm now permanently stuck on a pink screen.
Doesn't matter if I replug the HDMI, use different monitors, etc.
If there's a way to reboot without unplugging, that would be a good temporary fix.. but I'm a bit stuck.
Using Armbian 5.35 OPi Lite Ubuntu Xenial Desktop 3.4.113 (latest I believe)
