Hi Forum People
So, I recently did an upgrade of from Ubuntu 13.10 to Ubuntu 14.04.
I am using Unity, cause I like the layout.
Everything appears to have gone ok, except for the new lock screen thing.
If I lock the screen myself with Ctrl+Alt+L it works fine.
It goes to the new lock screen and it looks pretty and all the blah and I can get back in.
If I leave the computer idle and the system times itself out and locks the screen, the screen lock goes to the *old* lock screen (where the login is in the middle of the screen).
From this, I'm stuck. I can't do anything, the screen is frozen, and can't none of the keyboard or mouse things work.
The only thing I appear to be able to do is reboot, with R_Alt+Prt_Scr+REISUB.
Where can I even start to look for the problem?
Any help would be appreciated, I can't leave my computer alone by herself ...
