Public bug reported:
This is basically a request to set drm_kms_helper poll=N
This currently defaults to Y, which causes the mouse to get laggy / skippy /
jumpy and loses clicks d during disk usage.
This is really annoying, and is new (by comparison to Lucid) in 12.04.
If you are running into the problem now, and just want to test real quick if
this fix works, you can do the temporary:
sudo sh -c 'echo N > /sys/module/drm_kms_helper/parameters/poll'
To keep this change, do:
sudo sh -c 'echo "options drm_kms_helper poll=0" >> /etc/modprobe.d/local.conf'
sudo update-initramfs -u

Importance: Undecided
Status: Incomplete
