Do you happen to know the corresponding commands in CentOS?

I meant the nvidia-settings command.

My (unfortunately) last idea is to add BusID to the /usr/share/X11/xorg.conf.d/20-driver.conf file
BusID

Code:

Section "Device"
  Identifier "nvidia.driver"
  Driver "nvidia"
  BusID "PCI:1:0:0"
EndSection

When I run

Code:

nvidia-settings

, it tells me:

Quote:

You do not appear to be using the NVIDIA X driver.
Please edit your X configuration file (just run 'nvidia-xconfig' as root), and restart the X server.

I tried running

Code:

nvidia-xconfig

and then it created a /etc/X11/xorg.conf file. After rebooting, the screen again went black until I deleted that file. A lot of times, when my X server isn't starting, it works again after I delete that file. But that file is blank, so I'm not sure what's causing it to affect my X server. Any suggestions?

The one posted above (BusID). And no more ideas. Sorry.

The BusID method didn't work either. I really appreciate the amount of time and effort you put into helping though! Thanks.

Before, you were saying that NVIDIA proprietary drivers conflict with mesa though? How would you recommend I overcome that problem?

i subscribed to this thread a few days ago to see where it goes...

a little overhead info:

i read you are using centos; centos is basically the same as redhat, and those are server distros.
it means, their maintainers have little to no interest to keep up repos for proprietary gpu drivers.

so, my, very simple advice would be that you re-evaluate your choice of distro, and maybe install something more suitable for desktop use and/or gaming, or a nice, stable all-purpose distro like debian stable.

IF you are determined to continue solving this on centos, read on...

installing a suitable nvidia proprietary driver on centos most probably involves enabling some special repos and several more steps, most probably outlined somewehere in the centos/redhat wiki pages.
please search and tell us what you find.

additional difficulty is to determine in which current state of non-functionality your already installed nvidia driver is, i think that is what you were mostly working on in the previous posts?

i haven't read everything in this thread, but i would like to start by determining what sort of hardware you have there.
just tell us in your own words, or point me to a specific post where this was covered.

edit:
just found this https://www.linuxquestions.org/quest...0/#post5588284 might become relevant later on in the process
