Here's an older version of essentially the same thing: <https://forums.opensuse.org/showthread.php/541438-AMD-Intel-amp-NVidia-X-graphics-driver-primer> > I still don't understand why you recommend to use generic [1] > "modesetting" DDX module instead of vendor supplied and supported one > for your hardware. 1: The Modesetting DDX is newer technology. It's good enough that AMD stopped providing its fglrx driver for recent distro releases, and the Intel-specific DDX went into maintenance mode (no major version upgrade) 7 years ago: <https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/> 2: AMD and Intel contribute to FOSS openly, while NVidia still does not. > So "absence of nouveau" in those lines doesn't really tell anything, > because you still run "nouveau" driver in your system. Again, this was addressed by the inxi outputs I provided. Here one is again with less editing, where nouveau is present only as the kernel driver/module for the NVidia hardware device, while modesetting does X-specific duty: # inxi -GISay ...

NVidia's own software is thus needed only by those who need some specific feature only it provides. -- Evolution as taught in public schools, like religion, is based on faith, not on science.
