Server Version#: 1.41.3.9314  
Player Version#: N/A

I’m excited to try out HEVC transcoding, but after a few restarts and waiting overnight I’m not seeing the setting. I’m running an i7-10710U CPU with Ubuntu LTS (24.04.1, kernel 6.8.0-51 as of this writing). The only GPU listing I see in Plex is “auto” so I’m not sure if that means the card is seen or not.

Before I pull my hair out, I’m wondering if my system is even set up properly. Is there some way to verify that everything needed is in place? I see lots of information about NVIDIA cards, Docker setups, etc., but I’m just using an Intel NUC with Plex installed directly.

Any guidance would be appreciated!

What is the output for `ll /dev/dri`?

Is this in a docker or lxc? You have no GPUs in `/dev/dri`.  
`lshw -c display` to make sure the iGPU is seen and claimed by the OS.  
Also `id plex` and make sure it is part of video group.

No

Ran the lshw, not sure what this indicates:

```auto
sudo lshw -c display foxbjk@Zoidberg3
[sudo] password for foxbjk:

```

‘plex’ user _is_ in the video group.

So, the iGPU is not enabled or seen by the OS?

It looks like the i915/drm module might not be getting loaded successfully. What is the output of `sudo dmesg | egrep i915` ?

@FoxBJK What @pshanew states is correct. If the i915 is loaded correctly the configuration line from `lshw -c display` would reflect this:

```auto
configuration: depth=32 driver=i915 latency=0 resolution=1920,1080

```

From the provided information, it appears that your system is running in a fallback mode with a basic resolution of 800x600. This suggests that the nomodeset parameter is preventing the kernel from initializing the full graphics driver. The nomodeset kernel option disables the kernel’s mode-setting feature, which often limits the graphical capabilities and prevents the system from loading the proper graphics driver.

Did you have a reason for using `nomodeset`?

```auto
sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet nosplash"
sudo update-grub
sudo reboot

```

I’m traveling so it’ll be a few days before I can apply the update. But I’ll definitely report back
