NVidia NVS-315 support

[Merlin75]

Hi all,
I've recently made the switch to CentOS 8 from 7 on my dekstop. I have two NVidia NVS-315 dual-head cards. While this works fine with my 2x2 four-head display setup, I find that videos (youtube, netflix, etc) are wavy and laggy. On CentOS 7 I had installed the nvidia drivers in place of the nouveau drivers. I've tried following the same steps on my CentOS 8 machine but have run into road-block after road-block.
I believe I got it working once, but the first time I rebooted after that, my machine was basically bricked. All I got was a black screen with a mouse cursor. I couldn't switch to another console terminal, couldn't get out of X, etc.. Since it was such a fresh install, I just blew it away and re-installed from scratch again.

So now I'm left back where I started with horrible video experience, but at least I'm on CentOS 8!

Any suggestions for installing a better driver?

Alternatively, any suggestion for a better graphics card that might be more supported?

Thanks much!

I was trying to use the following guide:
https://linuxconfig.org/how-to-install- ... n-centos-8

Code: Select all

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF119 [NVS 315] [10de:107c] (rev a1) (prog-if 00 [VGA controller])
02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF119 [NVS 315] [10de:107c] (rev a1) (prog-if 00 [VGA controller])

The driver I've been trying to use:

Code: Select all

NVIDIA-Linux-x86_64-390.116.run

Unfortunately, what you need is provided only by nvidia. The closed source proprietary driver needs to support CentOS 8 and until then you are stuck.

The open source nouveau driver does not offer proper hardware acceleration for nvidia cards because nvidia won't release the needed information and refuses to submit patches, so people are forced to use their own driver.

I think there is an nvidia forum for reporting driver bugs, try to request support for CentOS 8 there.

Just for reference, in the Linux world, the best solution for high-end graphics are AMD cards because AMD has given a lot of special attention for full open source drivers. For low to mid-end graphics Intel is also quite amazing because they also provide full open source drivers. So yes, nvidia is quite simply not in favour of open source, but at least you do get a closed binary driver (and when it works, its actually a decent driver).

Great thanks for the info!

it shouldn't be too difficult to install the Nvidia drivers manually. I'd start with the current driver in the required series (390.132 at the moment). After installing from the run file, you do what a packaged version would do. Using the Elrepo package for 7 as a reference:

- Add 'nouveau.modeset=0 rd.driver.blacklist=nouveau' to the kernel command line,
- create /etc/modprobe.d/blacklist-nouveau.conf and put 'blacklist nouveau' in it,
- recreate the initrd with 'dracut -f'
- edit /etc/gdm/custom.conf to disable Wayland (look for the comment in the [daemon] section),
- supply a minimal /etc/X11/xorg.conf like

Code: Select all

Section "Device"
        Identifier  "Videocard0"
        Driver      "nvidia
EndSection

as a starter or use your old xorg.conf from 7,
- reboot.

Rpmfusion now offers a packaged version of 390.132.

You may want to enforce 'full composition pipeline', this will sync refreshrate.

- In Nvidia control panel you can set refreshrate to a better one, for instance my Asus laptop ROG is able to handle 120 hz.
- Together with full composition pipeline your experience with youtube, videos etc. will be more smooth.
