There is no signal coming from your computer..

[mathieu . malaterre]

Hi there,

 Everytime I go out for lunch and comes back to my desk I cannot get the screen 
to wake up. Apparently typing on the keyboard does not send any signal from the 
computer to the screen.

Using:
- debian 5.0
- dell precision T7500
- Display/Port cable

Thanks,
--
Mathieu
