Hi Liam,
seems to be the same problem as I recently pointed out to you for my
Linux box: as you mentioned yourself if you seperate the
device,decomposed=0 statement from the device,true=24 statement it
should also work (? cannot test it right now since I only have 8 bit
color at work).
Cheers,
Martin
