Oh boy, #Nvida hell with #Debian 13.
Nouveau power save suspend/resume doesn't work, so I tried the proprietary drivers. Which gave me a system that eventually switched to a black screen with a cursor. None of the usual keyboard shortcuts worked, not even Ctrl-Alt-Del
Eventually a LiveCD gave me a recovery terminal and "apt remove --purge nvidia-*" worked. Wasn't well documented except one place who assumed 'obviously you can boot to a terminal'. Nope.
But a LiveCD worked. So I'm telling you
