I've recently rinsed my laptop from a dual boot to a full Ubuntu (12.04)installation. I've done a fair few installations of Ubuntu at work, so I was surprised when my mouse started behaving erratically.

Ubuntu 12.04 (pretty fresh, so far only installed virtualenv, restricted-extras)
Logitech wireless mouse (forgot to check which version, at work now)
Samsung R730

Intermittent "laggy" behaviour - mouse moves very slowly, seems to float or overshoot target when occurring. This occurs sometimes when viewing webpages, or when opening folders - can't seem to pin it on a specific application being open.

Any ideas how I can go about remedying this problem?
