I displays jpegs with better color and finer resolution. Is there a better check than my eyeball available? > Did you try 24/32 bpp? Yes, I got them by default, but <CTRL><ALT>+ and <CTRL><ALT>- (+ and - on numeric keypad) don't seem to be working. > Is VRAM recognized (look at X startup messages)? Yes, I've seen a message that implies that 2048Kb is available on the vid card. > Did you read the README (in particular, do you need > to specify linear addressing)? Which README are you referring to? Any way, thanks for the reply - I'll try to research what linear addressing is and how to specify it and let you know how trying that works out. > > -- > Dimitri > > -- > TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to > [EMAIL PROTECTED] . > Trouble? e-mail to [EMAIL PROTECTED] . -- ----------------------------------------- Ralph Winslow [EMAIL PROTECTED] Someday soon I really MUST find a way to piss away a LOT of bandwidth on this .sig -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
