Here goes my "me too". Nouveau drivers causing locks in the graphics
environment, locking also the keyboard, disallowing me to switch to a
common non-graphic terminal to try something.  I had to install a ssh
client app in my smart phone so I could try to unlock the system (with no
success) and, at least, shut it down gracefully.

I'm also a KDE user.  I've noticed more locks while using "chromium", but
this might have been a coincidence.
