I have this bug with a Nvidia GT430, 4GB mem, AM2 X2, Ubuntu 11.10 64
bit. However, I haven't had it on my laptop which uses Intel graphics.
But I always use the touchpad there. It happens after unity has been
running for awhile. ctl+f2 then unity --replace always fixes it
temporarily. If I had a dollar for every unity --replace I've done since
11.04...

But, honestly, I like Unity. Just getting tired of the bugs. It runs
great on my laptop. 32 bit, not 64. 64 bit has java applet problems. If
stability is paramount, I advise waiting at least until 12.04 to try
Unity.

I also found that restarting Firefox fixes it for awhile. This makes me
think that there's a memory leak somewhere. Fortunately unity --replace
fixes most mem leak issues for awhile. Pretty common with the Nvidia and
ATI drivers. I haven't had any problem with Intel. I know that there's a
slow Xorg and Compiz mem leak. It was much worse before I replaced the
onboard ATI with the Nvidia GT. Oh, I'm so tired of memory leaks :-(

You can check this out by running top in the terminal. The actually
percentage isn't as important as just comparing it to what's normal for
that process. Xorg usually starts out below 1% and slowly creeps up.
Compiz starts around 2%, and rises more quickly. I usually get a
noticeable slow down at around 5%.

I restarted firefox about 10 min ago, and the choppiness is back
already.

I'm also wondering whether this problem exists on a 32 bit install, or
if it's just a 64 bit issue. I've generally found the the 64 bit system
is more abundant in bugs.

I haven't tried the mouse polling trick yet. It doesn't sound like it
always works. It could be that the mouse is somehow exacerbating the
memory leak.

I also tried running in Gnome-Shell, and had no problems there, but I
only used it for a day or two.
