I don't know what was updated in the last Ubuntu update--maybe OpenGL or the X server--but after rebooting my Unity desktop comes up with a blank, gray screen. Clicking on a menu item makes the screen flash for a second. A Gnome Shell environment will boot, but there are display issues: clicking on some items in the dock turns the screen blue.

Gnome Classic won't boot, but Gnome Classic without effects will show properly.
 
I had the same problem...disabled 3D, reinstalled parallels tools...still same problem. Reinstalled parallels tools a 2nd time and now all is working, even with 3D enabled again.
