There is a little problem here for me. On this z930 laptop, I get some temporary freezing of external keypad and mouse: logitech mk320, and external mouse only: logitech laser.
At first glance, I though the computer was the problem. However, I am on crunchbang actually and I do not get that type of behaviour.
After verification, in always fresh mode, I get the same behaviour, but with all my modules left in. After the complete cleanup of the modules section. The problematic behaviour subsides.
I will come back to report on the faulty module.

Prendre son temps, profiter de celui qui passe.
