That's strange... That was the exat text I typed to cmdline.txt when I tried to make PINN work without monitor. I even copy & pasted the text to the file opened in nano, in SSH. Everything was in one line too.I think there must have been something wrong with the way I typed in the video mode, because I have just retested PINN v3.9, v3.9.3 and v3.9.8 and all of them work headlessly on a Pi5 if you addto cmdline.txt. The capital 'D' is the important letter to create a framebuffer even if no monitor is attached.Code:
video=HDMI-A-1:1920x1080@60D
I think I have to wait until next month to be able to buy 'Dummy HDMI Plug-in', but since I could find only HDMI one, things would be messy because I'll have to buy 'HDMI to Micro HDMI Converter' too...

Do I have to put 'video' stuff in both 'cmdline.txt' of PINN and OS installed by PINN?
When I did that, I've only put it in RPi OS Lite. That could be the reason of the problem, I guess...?
