I get to buy myself a beer - boring.
I believe this is totally non-intuitive - but that is just me. I dropped the laptop in a docking station, connected a Dell monitor and a mouse, and kudzu self-configured the unit and the display works both on the monitor and the LCD display. Once configured, the LCD works stand-alone without whimpering.
Since this laptop is 3 years old - a dinosaur in IT years - it will often be found in a carry bag rather than near a docking station. So it has to have RedHat set up as a desktop machine before it will function as a mobile machine. Very strange. Anyone else have an experience like this?
