centos 7 - kmod nvidia


Hello Linux-world

About myself:
I'm running my own small 3d-studio. Until now I was on Win7 in my office. Working in other companies I mostly was on centos or kubuntu (not setting it up but using it as an artist). Now I'm trying out different linux-distros for a possible win to linux switch.

Since its 3d related I need nvidia-drivers. I came across the fact that it seems to be better to use kmod-nvidia ..rather than manually installing it.

http://linuxsysconfig.com/2014/09/nv...s-on-centos-7/
http://www.dedoimedo.com/computers/c...ia-second.html

At works good ..up to the point where I did:
yum remove xorg-x11-glamor

after a reboot there was no more input device working .. which kind of makes sense since I saw the command removing ALL input devices .. with a fresh centos7 install and reinstalling kmov-nvidia WITHOUT removing glamor it now seems to work fine .. should I leave it like that? .. concerning ATI-stuff I mean

any reason for that? why do the above links/tutorials suggest to remove all input devices? or did something other happen here?

thanks

the kmod rpm is the same driver as the nvidia.run

this is not a problem on 5 or 6 ( i do not run 7 so)

the kernel and the kmod ARE!!!! A MATCHED SET!!!
as in if the kernel is updated the kmod MUST MATCH

normally both are released at the same time ( this was not the case a few years back on Fedora )

but i have been running the nvidia.run for many many years and it really is not that hard to support



issues with the nvidia.run

it REPLACES !!! the default "GL.h" and GLu.h headers
and replaces the default libgl with nvidia's custom version ( that matches the source headers)


so

programs that are built with the NVIDIA.run and the nvidia gl headers might NOT RUN!!! if the default MESA gl.h and glu.h and mesa version of libgl is used

and visa versa

so i reinstall the mesa GL and mesa-devel rpms after reinstalling the nvidia.run after kernel updates


but the kmod-nvidia.rpm is easier and normally is not a issue




EXCEPT!!!! FOR!!!!
the change from using Nouveau to the nvidia driver

that first change can be a pain in the rear

the kmod SHOULD!!! add a blacklist for the nouveau driver
BUT!!!
you need to rebuild the boot image WITHOUT the nouveau driver ( first time only)


see the fedora nvidia guide for grub2 and cent7

thanks for these infos.

as mentioned, it seems to work now. I did have 1-2 freezes but that can't be related to possible nvidia-ati conflicts.
