There is fundamental reason for that. Nvidia does not disclose/publish sufficient information about their chipsets. Therefore, there is no decent way for open source programmers to write good driver (that will account for framebuffer layout and variety of other internal things). Hence, crappy open source drivers covering only generic functionality. To the contrary (in the past at least), ATI (bough out by AMD, and still continuing similar attitude under the hood of AMD as I observe) was publishing sufficient information about their cipsets. Hence, great open source drivers were always available for ATI video chips. And no matter how much the main Linux crowd was praising Nvidia, I always was a rebel praising my lifesaver: ATI (and disliking Nvidia to tell it in the mildest words). <rant> To mention one more thing about Nvidia, just in general, not related to anything here. Macbook Pro 15 inch by Apple at some point was coming with discrete Nvidia chip. There were was at least one model that had these Nvidia chips with the bug in silicon, which was discovered with release of next MacOS version. All those machines with bad Nvidia chips were stuck with older system, and Apple (there they deserved my extra respect!) started program to replace all these machines with bad Nvidia chip for free. But the program was stopped really quick, and my guess is: because Nvidia (the guilty party in my book) refused to carry their share of financial burden in replacing bad hardware. Right there Apple switched away from Nvidia, to ATI (AMD) video chips. For good, at least as I observe so far. </rant> > > Exactly my impression.
