I was trying to do setup rotation on my tablet, but when I tried to install the advanced-backlight package I was getting an error message about libhildondesktp0 and libhildown dependcies. I proceed to remove them so I could uninstall them. However, it uninstalled more than that and the screen went blank. So I shutdown my tablet and turned it back on and went to settings and tried to open up the applications manager, but it wasn't there. Then I went to see if control panel was still there, but its not. Those are the only two things I'm missing. Has anyone else come across this problem and come up with a solution?

Regards
