I have a dell T3620 workstation with nvidia NVS 315 video card.

I installed the video card driver with following commands:

yum remove xorg-x11-drv-nouveau*
yum install nvidia-x11-drv.x86_64 nvidia-x11-drv-32bit.x86_64

after reboot, I can run the nvidia-settings gui tool, but can't change the resolution, the highest resolution is 1024x768, but my LCD support up to 1600x900. My LCD only support VGA port, so i used a DVI to VGA convertor.

the xorg.conf is like this:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 375.26  (buildmeister@swio-display-x86-rhel47-01)  Thu Dec  8 19:06:44 PST 2016

You can use nvidia-xconfig, from a terminal. nvidia-xconfig will find the X configuration file and modify it to use the NVIDIA X driver. In most cases, you can simply answer "Yes" when the installer asks if it should run it. If you need to reconfigure your X server later, you can run nvidia-xconfig again from a terminal. nvidia-xconfig will make a backup copy of your configuration file before modifying it.

Note that the X server must be restarted for any changes to its configuration file to take effect.
