Public bug reported:
Binary package hint: gnome-control-center
The last version of the Kernel where this problem DIDN'T happen was
2.6.32-35. With every kernel since, as the number of open apps (and,
I'm assuming, memory usage) increases there are jags where the trackpad
or mouse become almost non-moving. The speed of the cursor motion drops
to almost zero and the delay is astonishingly long. Eventually, if you
stop moving and wait, the mouse will catch up to your current position,
but any usage thereafter causes the same problem. Stopping and
restarting doesn't help. When I revert to the kernel mentioned above it
works fine, but every kernel since has had the problem. The problem
seems much worse when the PC is attached to its docking station, but
even when using the PC on its own I can see the small blips that will, I
know, mean the mouse/trackpad will be unusable the next time I hook it
up to the docking station.
