A few minutes ago I lost complete control of my USB live session of Mate 17.3. It just quit responding. I have no user control at all.
The menu will not respond, I was unable to quit the session. Went to shut down by the user interface [GUI] got part way thru the process, black screen came up mate started to shut down and then I get an error pop up. "you will not be able to reestablish user account control" then went into a loop. Tried to shut down, error message, click ok back to error message repeatedly.
Finely had to just force a shut down with the power button. Removed the usb and rebooted back into cinnamon to report here.
Firefox would not even work anymore. Will await advice before proceeding further. Hope some one is here.
