I had this problem for a while. As long as the system was actually running (ssh to it from another machine) I could get it back using Alt-Ctrl-F12 Alt-Ctrl-F2, which gave me what looked like a login screen, but was actually just an "unlock" screen. Sometimes the system had completely halted: I run gkrellm, and when the graphs stop moving, I knew it was hung. And I couldn't ssh to it. I had to reboot after those hangups. I don't know whether it was Firefox or KDE or Wayland or a hardware problem. My computer lives in a little cupboard under my desk. I run with the door open now and it doesn't happen anymore. Maybe it was a thermal thing in the video card. I'm pretty sure it wasn't a thermal thing on the CPU because the temperature shown by gkrellm was below 40°C
