I have researched my problem on Google; but, I can not find a fix and I do not know why my desktop is not showing. Only the background wallpaper shows up. I also tried Ctrl-Shift-F1 and removed compiz compiz-core then the same thing, and I also tried reinstalling
ubuntu-desktop but again the same thing!
Does someone know how to fix this? I don't want to reformat my Ubuntu drive.
Fixed: apt-get upgrade
