CentOS

I have a new Dell Precision 7740 with a NVIDIA Quadro RTX 5000.
I tried to install the NVIDIA Linux driver: https://www.nvidia.com/Download/driverR ... 9360/en-us
With the following errors:

Where do I go from here?

Use ELRepo's nvidia-detect and kmod-nvidia packages

Use ELRepo's nvidia-detect and kmod-nvidia packages

TrevoH,

Thank you for your fast reply, and I have used your advice in the past and want to thank you for that as well! Could you break it down for me (a.k.a. dumb it down).

I currently use RHEL 6 at work, cut my teeth on Linux - RHEL 5 on the job (2015). Just made the jump to running Linux and my primary OS on my new computer and will run windows in a VM for windows things I need to do. But trying to get things to work in this aspect is above my skill level.

Google for "ELRepo" and go there. The front page there is either a "getting started" or has a link to it. Install their elrepo-release file for el8, yum install nvidia-detect and once installed, run it and it will tell you which of their kmod-nvidia* packages supports your card then you yum install that one. It does, or should do, everything for you including blacklisting nouveau.

On the ELRepo page I followed the instructions for getting started - no issues until:

[root@localhost ~]# yum install nvidia-detect
CentOS-8 - AppStream 396 B/s | 4.3 kB 00:11
CentOS-8 - Base 1.2 kB/s | 3.9 kB 00:03
CentOS-8 - Extras 179 B/s | 1.5 kB 00:08
ELRepo.org Community Enterprise Linux Repository - el8 1.1 kB/s | 2.9 kB 00:02
No match for argument: nvidia-detect
Error: Unable to find a match: nvidia-detect

Was at a dead end. Poked around the ELRepo page and found the rpm for my card and remembered at work back when we had RHEL 5 we would always have to drop to single user mode and reinstall the NVIDIA drivers after most patches. So I switch my run level: systemctl set-default multi-user.target - rebooted and logged in as root then installed the rpm. Switched my run level back to graphical.target and rebooted. This did not fix my problem. However, when I run lspci my graphics card is now listed as a device. This is something that was not there before.

root@localhost ~]# lspci
~
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Mobile) (rev 02) <-- What is running
~
01:00.0 VGA compatible controller: NVIDIA Corporation TU104GLM [Quadro RTX 5000 Mobile / Max-Q] (rev a1) <-- Was not listed before
01:00.1 Audio device: NVIDIA Corporation Device 10f8 (rev a1)
01:00.2 USB controller: NVIDIA Corporation Device 1ad8 (rev a1)
01:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1ad9 (rev a1)

I have to call it a night and get back to this tomorrow evening after work.

when I run lspci my graphics card is now listed as a device. This is something that was not there before.

I suspect you didn't look hard enough before as lspci shows the hardware that's installed and is not affected by what drivers are installed.

It appears that nvidia-detect is in the elrepo-testing repo, not sure why it's not made it out to the main one yet so dnf --enablerepo=ekrepo-testing install nvidia-detect then run nvidia-detect and it should tell you which package to install.

Since you have two graphics cards you may need to use bumblebee bt I don't have any experience with that or the nvidia drivers on CentOS 8 so someone else will need to help.

Solved. Was not able to work on this until this morning.
Thank you TrevorH for your assistance.
Ran: yum --enablerepo=elrepo-testing install nvidia-detect This was successful and I ran nvidia-detect. The output told me to install a older driver: yum installkmod-nvidia-440.64 this downgraded: kmod-nvidia-440.82-1.el8_1.elrepo.x86_64 to: kmod-nvidia-440.64-1.el8_1.elrepo.x86_64 Rebooted the machine and nothing changed. So I went into my bios under current configuration listed two video controllers: Intel Corporation UHD Graphics 630 (Moble) (Rev 02) and NVIDIA N19E-Q5. Then I looked under video controller there was a screen "Switchable Graphics" I had the check box "Enabled Switchable Graphics" It stated "It should only be enabled for Windows 7 and later version of Windows or the Ubuntu OS. The feature is not applicable to other Operating Systems." So I unchecked that box and checked the box "Discrete Graphics Controller Direct Output Mode." Saved my settings and this changed my Video Controller to just NVIDIA N19E-Q5 the Intel controller was no longer listed. Rebooted and this made a significant change to my display for the better. However under Settings-About-Graphics: llvmpipe (LLM 8.0, 256 bits) was listed. No NVIDIA Controls were available under Applications. So I re-installed: rpm -U kmod-nvidia-440.82-1.el8_1.elrepo.x86_64.rpm Rebooted nothing changed. I started googling nvidia control and nvidia control panel packages came up. I read that I need to run "nvidia-settings" This erred out. So I ran yum whatprovides nvidia-settings one of the results was matching my rpm driver I installed so: yum install nvidia-x11-drv-440.82-1.el8_1.elrepo.x86_64 Reboot and success!
