Lock Screen Froze

I installed Prometheus today. I went to walk away from my desk and as is habit for me I locked my screen. When I came back all I had was a black screen with a cursor and it would not respond. The cursor would move but I could not get the login screen to come up. After some time it appears that “X” crashed as it dropped me to a bash login That is also non-responsive. I was building a VirtualBox at the time so I will wait till the HD activity slows and do a hard boot. Curious if anyone else has experienced. Thanks Bob

Same thing here!
