Comment 6 for bug 151621

I have the same problem and can also confirm that it affects Hardy. At first all I knew was that the pointer was sometimes disappearing in Firefox, but now I see that Cory's description is right on the mark. (I haven't tested HWCursor though.) Since the original posters haven't responded to the request for more information, I am going to take over. My machine is a Dell XPS M1710 laptop with an NVIDIA GeForce Go 7900 GS running Gutsy, but with the Kernel/Compiz/X/NVIDIA packages and various others installed from Hardy. See the various attached logs and info.

Changing to Confirmed and adding linux-restricted-modules-2.6.24 as an affected package. (I will leave it as New there until someone else confirms in Hardy too.)
