I have Ubuntu 11, 64 bits, on my Asus laptop.

My mouse is a Logitech nano wireless.

Everything works find out of the box, except the keyboard and / or the mouse seems to bug sometimes :
- clics doesnt work anymore
- some keys doesnt work or seems to change

I don't do anything special when it begins to bug, and it really seems to be random : i can have no problem at all in 2 hours, or 2 bugs in 10 min.

The only way i found to fix it is to reboot the system...

Does anyone have an idea where it comes from please ?
