> I think you problem lies with compiz or some setting you made with desktop effects, but IMBW. I had the same problem with ALT-F2 using compiz in gutsy until someone told me that compiz doesn't support it or something to that effect and told me to rm compiz. I did and ALT-F2 popped right back up. I'm not sure ALT-F2 is available in compiz. Maybe someone elso does.  When I installed intrepid on a new partition, compiz is installed but I don't use it and ALT-F2 still works. You probably can't access the add widgets plasmoid now but it may allow you to get you panels back. I'm using kde4.1 in Intrepid so I don't know if it applies to gnome but expect it does.
Well, I've been checking, and the settings do stick across kernels, so 
I'm not going to be removing my beloved commpiz as I'm addicted to my 
four desktop interface. I don't think that's it.

I'm sorry, but Leonard sound more like he's guessing than anything, so 
I'm going to wait and see if someone who actually knows about this 
problem answers. It's running fine in this kernel at the moment with the 
setting changes I made, and I haven't tried a boot back into the newer 
one yet, so maybe it won't even be a problem anymore if I do.

Later, Ray Parrish
