Stuck at lock screen – Ask Ubuntu

I was working on a text file a minute ago. I locked my screen to make coffee and I come back and my lock screen is unresponsive. I can move the mouse, but I can’t click anywhere and my keyboard doesn’t do anything.

I can SSH into the computer and everything seems to be fine.


  1. Can I kill the process that is the lock screen? This seems like a security hole, but I suppose maybe not really if I can already ssh and do everything else.

Or :

  1. Can I find the temp file for a textedit document and save that real quick, then just reboot the computer?
