We reformatted an old dell windows xp with linux.

My wife chose a movie pic as the desktop background and movie image as screensaver. Then upon leaving the computer idle for an hour, when we return and clear the screen saver, ALL the desktop icons are gone! There are no taskbars or anything to click on. We have full operation of the mouse but cannot do anything. Control-Alt-Delete does not engage either. We have to hold the power button in to shut it down and restart it.

Anyone know how to help????????????

THANK YOU!!!!!!!!!!
