I’m also receiving nothing but a black screen after installation. I had been using openframe for several months with no issues. A couple days ago, with no changes or other intervention to my RPi or anything installed on it, it simply stopped working. I spent a couple long days trying to get it back where it was, but to no avail. It was initially on Raspbian, but I decided to try NOOBS–I get the same result. Here are some details:
OS: NOOBS 3.5.0 (9/15/20)
Running in CLI
GPU mem set to 256 (also tried 512)
When I attempted to run from within the desktop environment, I received an “inappropriate ioctl” error.
Running from CLI, it goes to a black screen.
Booting with “n” held down makes no difference whatsoever.
Any assistance you could provide would be helpful. I’m simply (and desperately) trying to get it back to where it was before it randomly flaked out.
