Actually, this _is_ a driver problem. It went away at some point in the
11.10 cycle but is back again with a vengeance in the 12.04 cycle. To
those who dismiss this as a problem with the hardware, it really isn't.
Something is being set within the graphics card that is causing this.

the back lamps, because if you switch off your pc and after one minute the
