Didn't try yet. I didn't know the IP address and my firewalls are locked

try. If I did get in, what should I look for? tail of logs, dmesg???

there would be nothing to debug.

I didn't try that yet either... would that be ctrl-alt-F2? Again, what
commands would I run to capture useful data on a partially responsive
graphical session?
