After using Fn:

1. Left-clicking on menus causes them to be highlighted, but they do not open up. (Normally they open on click, even without releasing the button.)

2. Mouse pointer behaves erratically. It responds, but jumps around at random.

3. Process hald-addon-dell-backlight starts hogging the CPU.

Confirmed that (Ctrl-Alt-F1) and (Ctrl-Alt-F9) makes it work again and undoes all of these problems.

After clicking menu and then using this fix, menu is still highlighted, and hovering over it opens it up the rest of the way, without clicking anything.
