Server Version#:plexmediaserver_1.29.1.6316-f4cdfea9c_amd64.deb
After doing the most recent update, I see this in the console.
PlexMediaServer install: Nvidia GPU card: Not Found
I have a P2000 installed and the drivers too on Ubuntu Server 22. I do recall at one point seeing a stream to an off-premise device showing (hw) in the console.
How can I make sure Plex is properly detecting the card?
If the installation script is not seeing an i915 then I presume you have an AMD CPU?
If you do not have /sys/module/nvidia/drivers/pci:nvidia/*:*:*:* then the card is not being seen by the kernel.
@ChuckPa this is what I have:

Notice you can see the PCI slot addrees
You are showing nvidiafb which is only a display FrameBuffer surface. It’s not a rendering GPU node.
Which Nvidia drivers are you using?
I am using 510.85.02

Also please notice now nvidia-smi shows you the PCI address 00000000:07:00.0
I was unsure which ones to install so I went to Nvidia’s site and downloaded the drivers from there. Which package did you use on Ubuntu?
The complete list of Nvidia packages I have installed is:

If I remember correctly, nvidia-driver-510-server and apt pulled in the rest.
For this machine, xorg isn’t needed; it’s a headless server.
nvidia-driver-510-server seems to have been the correct package name. It installed and the server rebooted.

# nvidia-smi
Failed to initialize NVML: Driver/library version mismatch
Not sure how to fix this mess.
Since I don’t have an update to install, what’s the next best way to see if Plex “sees” it?
Very carefully look through all your installed nvidia package versions (dpkg -l | grep nvidia).
They all must match exactly.
The error shown here occurs when nvidia-smi is expecting a different version than the kernel driver has.
If you’ve also installed the DKMS packages, rebuild the initrd ramdisk and restart
@ChuckPa it took a while but I was finally able to find everything installed by apt, dpkg, .run file and even looked in ldconfig to make sure it was all clean of anything nvidia. Just did a clean install of nvidia-driver-510-server
Does this look normal now?

Now that looks normal.
Look at nvidia-smi and how /sys/module point to 0000:05:00.0.
Now you have proper driver installation.
What’s the correct way now to see if Plex properly detects the GPU and uses it?
If your CPU is an Intel 4xxx and above, with exception of a few SKUs, it will create cause node /dev/dri/renderD128 to be created.
If it is an AMD, AND the nvidia is detected, you should see also see /dev/dri/renderD128
This is my machine with P2200 Nvidia

If you see “renderD128” (from the Intel CPU) and “renderD129” then “renderD129” is the Nvidia (The kernal starts counting at 128 and increments with each device)
To tell PMS which rendering device to use:
HardwareDevicePath="/dev/dri/renderD129" before the closing />Preferences.xml will look like this:
SomePreference="Value" HardwareDevicePath="/dev/dri/renderD129" />
Seems I do have the renderD128

My processors are 2x CPU Intel Xeon E5-2680v3. I haven’t rebooted the server but I did restart PMS. So, since I have the renderD128, I should be all good now?
That is good to go.
As final check, make sure user plex is a member of group video.
If not, add plex and restart PMS.
It already is in the video group. Looks good now. I’ll watch for certain streams to see if it shows the (hw) and go for there. Thanks for the help!
