I just did all the stuff that is described in NVIDIA hp (I think!) and the only thing that I get when I try to start X is no screens found. Ive already tried to use other versions of NVIDIA drivers.. but the same problem happens. Im using RedHat 7.2.
What is the log saying in /var/log? it could be failing because it is reading info on your monitor, and you monitor is limiting the modes due to refresh rate… if this is the case, as it was with me, you have to add the following…
If you can not even start X do I guess that you are using the wrong driver. If you downloaded a precompiled binary so check that is was for your kernel. In the case what you compiled it so check that the kernel sources and headers really match with the kernel you are using.
