Bug Report: NanoPi R6S shows only a black screen after boot

Blind55 commented 1 month ago

What happened?

Upon boot, the bootloader (Ubuntu) screen shows up with its spinning wheels. However, subsequently, the login manager only shows a "black screen" (the mouse cursor, however, is visible, and movable). Switching to the console with alt-ctrl-F4 shows a normal login prompt. Switching to the console and back to the graphical environment lets one for a brief fraction of a second see the 'create your account' window, but immediately the screen turns back to black.

What resolution are you using?

Blind55 commented 1 month ago

I have tried standard HD (1920x1080) and UHD (3840x2160). I was trying to adjust the gdm3 config in /etc/gdm/custom.conf and switch to xorg instead of wayland, but that didn't seem to change anything. I have the feeling if I blindly set the mouse to the right locations, the GUI would let me create the account - if I could see the windows ... they appear to be functional. In summary, something ('black') seems to be overlaying the (functional) window system.

A few further comments:

22.04 seems to have the same issue
I cannot really do much with the system online as there is no account I can log into, I think (makes it hard to see the logs, really)
I can, however, try to turn off services having mounted the partition in a different system. It would be helpful to know where I could start, if there is a target service I could try.
The newest release appears to not open the window for account creation, as far as I can glean from the very brief switches from console to graphical interface (before the graphical interface goes black)

Same issue here (Version 2.3.1, NanoPi R6C). I thought moving from gdm3 to lightdm worked, since I got the desktop to show. But as soon as I move the mouse, it's gone again. Interaction still works (mostly keyboard). I suspect it is more a GPU driver issue than a window manager issue.
