Using Unity 3D, after leaving the computer for some time and logging back on the USB mouse is very delayed/laggy. Touchpad works fine.

Hi Jack,

When this happens, do you notice a high CPU load? (Check by running `top`). Also check if your RAM memory is low (`cat /proc/meminfo`)

[Jack Leigh (leighman)]

CPU load for Xorg is 1 or 2 %
Only other thing is Opera ~ 17%

cat /proc/meminfo gives

Doesn't seem like either of those are the problem.
As mentioned above the touchpad still works fine when this occurs

Hey leighman,

Hi, thanks for reporting this issue during the development period of
Ubuntu.

I notice there's not been further comments to the bug report since the
release came out, would you mind updating us on the status of it in the
release?

Are you still able to reproduce the issue? If not, do you think the bug
report can be closed, or do you think we should continue tracking it?

[Jack Leigh (leighman)]

I can still reproduce this.
