It is probably due to rnffedeices in the video cards and the video card capabilities between the two machine. (Not that the 2nd machine that doesn't show the graphics is slower or worse, it just might not be supported by the default drivers included in mandriva.)Seriously, I would check out a different distro, I have been burned 3 times in the past with mandrake/mandriva when they have decided to radically change the directory structures on the update sites without warning, and the systems became a Pain in the Arse to get updates for, not to mention some really bad bugs on version upgrades, etc.Mac user since 2000.
