I managed to install Karmic by de-selecting all UBS packages, including audio. I'm shocked that I still have problems with this new version too! Without anything enabled (nvidia proprietary drivers, any software installed) I get a sluggish mouse! (its a logitech laser, wireless) I checked to see if the whole system was sluggish but processes are not eating up CPU and keyboard is responsive. Anyone know why the mouse is acting weird? I've had it before in UBS but never on the generic kernel. I've googled the problem but no real solutions found. </pre> </blockquote> I was having a similar problem recently on a desktop install. My problem was resolved by moving a wireless router that was near the computer to the other side of the room. I have been using a Logitech VX Nano wireless mouse, which operates at the 2.4ghz freq; along with bluetooth and wifi. By moving the mouse receiver to the front of the case instead of the rear and moving the wireless router across the room, the problem dissipated. If that doesnt help, perhaps there are some log entries that are coming up? It may also be productive to go through Xorg.0.log to look for errors or duplicate entries perhaps. I'll assume you've gone through the basics of trying a different mouse - and wired compared to wireless.
