Hi, for some reason if I leave my computer idle my keyboard and mouse freeze. Sometimes after only being idle for a few moments, sometimes several minutes. Furthermore, this only happens when I am connected to wired internet. Don't have wifi here, so I need to use the cable.

I tried using different browsers and that didn't make a difference. I also think this may occur, even when I'm not using a browser, as long as ethernet is connected.

Any ideas of how I can prevent this? Rebooting after every freeze becomes annoying, especially when it starts happening more often.

System/Set up Details:

Dual-boot XP Home and Ubuntu 10.04LTS
Toshiba NB200 Netbook.

Tried to do a search but none of the cases I saw seemed to fit my situation exactly.
