Desktop responsiveness error

[Knapp]

First I want vent. I upgraded to 10.10 and was greeted on reboot with
a GRUB can't boot error!! Turns out lots of people are having this
problem and it was a quick fix but WHY??? This is December!! Bugs like
this should be fixed!! Also my WiFi was bored because the upgrade
installed Knetwork one AGAIN!

OK on with the real problem, when I put my mouse on the top or bottom
and expect the menu bar to pop up, it often does not until after a
long pause. Perhaps the pause in 5 to 10 seconds. There are other
things that pause to like updates to windows when switching programs.
This error is on both 10.10 and 10.04. I have no idea how to fix it.
64 bit Kubuntu 10.10 Nvidia prop driver 260.19.06 Geforce 7600 GS. 4GB
ram amd x2.

Thanks!
