I encountered no errors during the process. Towards the end my background went black but i wrote that off… I looked at the other answers with the Oh No screen but my case seems different since I can’t get to a login screen via ctl alt f3, or the other keystroke variations.
I changed from gdm3 to lightdm and now I can get to the splash login screen. When I login it just goes back to the Oh No screen unfortunately. My touchpad can move the mouse but not click.
I plugged in an external mouse and now i can try different desktop options. Selecting Wayland got me a black screen, however OpenBox actually worked. So I no longer think its an nvidia driver issue. Maybe it has to do with my track pad??
Any hints at this point?
