kernel-4.18.0-193.6.3.el8_2.x86_64 update broke kmod-nvidia driver functioning

Hi All,

I just updated my system from kernel-4.18.0-147.8.1.el8_1.x86_64 to kernel-4.18.0-193.6.3.el8_2.x86_64. Prior to this update, I had installed the kmod-nvidia-390xx.x86_64 packages to get nvidia driver support for my legacy nvidia card (Quadro 4000):

Code: Select all

yum list installed | grep nvidia
kmod-nvidia-390xx.x86_64                           390.132-2.el8_2.elrepo                            @elrepo      
nvidia-x11-drv-390xx.x86_64                        390.132-2.el8_2.elrepo                            @elrepo      
nvidia-x11-drv-390xx-libs.x86_64                   390.132-2.el8_2.elrepo                            @elrepo
This had been working perfectly for some time in kernel-4.18.0-147.8.1.el8_1.x86_64.

After the kernel update, the nvidia driver appears to be working:

Code: Select all

lspci | grep VGA
05:00.0 VGA compatible controller: NVIDIA Corporation GF100GL [Quadro 4000] (rev a3)
However, now when I attempt to run the graphical applications I normally use, there's a problem. Launching one such application from the command line produces this output, and the OpenGL viewports in the app don't work:

Code: Select all

RuntimeError: Viewer tabs require at least OpenGL 4.2. (Detected "3.1 Mesa 19.3.4".)

I don't know why, but there are a large number of mesa packages installed:

Code: Select all

along with the nouveau driver:

Code: Select all

yum list installed | grep nouveau
xorg-x11-drv-nouveau.x86_64                          1:1.0.15-4.el8.1                                  @AppStream
The nouveau driver is blacklisted, and I examined the /etc/X11/xorg.conf file, which appears to be okay:

Code: Select all

Does anyone have any ideas as to what's wrong, or how to fix it? Previously, I would manually install the nvidia drivers from an nvidia .run file, but I hoped using kmod-nvidia would shield me from that. Now it appears to have made the kernel update process even more of a headache. At least I knew how to manually install the driver - now I don't know how to fix this.

Thanks, mitch

You need to update kmod-nvidia-390xx, too.

Thanks, but that doesn't appear to be the issue:

Code: Select all

sudo yum update kmod-nvidia-390xx.x86_64 nvidia-x11-drv-390xx.x86_64 nvidia-x11-drv-390xx-libs.x86_64

Dependencies resolved.
Nothing to do.
Complete!

What is the output of glxinfo? It should contain the line "OpenGL vendor string: NVIDIA Corporation".

Code: Select all

glxinfo | grep vendor
server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
OpenGL vendor string: VMware, Inc.

Hmm. What does this mean?

It means your using software rendering -- donated by VMware to Mesa.

Okay - that would explain the behavior I'm seeing. Any idea how to configure the system to use hardware rendering instead?

I'm also seeing this:

Code: Select all

glxinfo | grep "direct rendering"
direct rendering: Yes
Doesn't that mean hardware rendering is enabled?

Direct rendering does not imply hardware acceleration.

I guess you need to go through the logs to see where things go wrong. First thing to check is probably whether the nvidia kernel module was successfully loaded or not.
