I hadn't thought of that! Now I see why you wanted to know the hardware
etc. Maybe I was a bit naive, :-) Just for the record: ASUS L5800C,
Radeon Mobility 9000, TFT@1400x1050, updated bios (so no black screen
stuff anymore, ;-)
But if I'm able to set up multiple screens or something like that, how
do I go about running, for example, xpdf -fullscreen presentation.pdf?
Thanks so far,
David
