i need to enable the tripleframebuffer of the nvidia driver for my geforce780, however when i create xorg.conf by using nvidia-xconfig and rebooting, emerald (and other packages) reports that glx could not be found. - and everything is stuttery and tearing.
if however i run my card without using xorg.conf everything is fine, though i cannot enable the tripleframebuffer.
ive tried using nvidia-xconfig AND merging it with nvidia-settings with the correct options > xorg.conf
This strikes me as particularly weird because in my previous installation of Fedora23 the xorg.conf worked fine, ive even tried using the xorg.conf from that install, which has the same hardware, driver etc.
