Intel NUC (12th Gen) + Ubuntu 22.04 LTS - Tips & Tweaks

Plex Media Server
1

Server Version#: 1.31.2.6810

Ok so I just got a 12th Gen Intel NUC with a 1270P and am running Ubuntu 22.04 LTS and Plex directly on Ubuntu.

Already asked about NFS mounts and tweaking in another post but was wondering if anyone had any suggestions for my setup or something that would work with my setup to tweak the speeds or anything similar (CPU, power management, etc etc). To get the best out of it transcoding and performance wise.

Only thing I tweaked was setting Persistent Display Emulation or something in UEFI so that it pretends a monitor is attached - so far I think its working as HW transcoding is working fine within Plex.

Thanks in advance!

Don’t mess with the UEFI.

Get a 2160p (or whatever) HDMI dummy plug.

That way, the machine works as you see it on your display while configuring.
When done, Unplug Monitor → Plug-in Dummy

Nothing on the box changes.

Dummy plugs can be had just about anywhere.

example:

So the UEFI setting on the Intel NUCs isn’t worth using then?

If you’re sure then off I go to order a display plug lol!

Are there any other tweaks I can do on Ubuntu 22.04 LTS Server Edition or is it all working as good as can be out of the box (barring the display issue)?

Thanks for all the help really appreciate it!!

  1. NUC in full UEFI mode with the display attached just as you would want it.
    (defaults on the display for most people is just fine). (this is where I install Ubuntu server and not workstation (why waste the GUI memory???)

  2. enable and start SSH

  3. put a HDMI plug into where the monitor was plugged into

  4. From here on out, you’re accessing it via the command line over SSH instead of via the monitor… but both are still shell command line mode

Cool will get the plug instead of using the UEFI toggle then - I trust you on that one !!

Yep I’ve only installed Server no GUI at all on the NUC.

So beyond that are there any other tweaks I can do to get more performance out of Plex on it or not really?

I like 64 GB in an Intel Core-class machine. They like that. 2x 32GB or 4x 16GB (depends on box). You want dual-channel mode to enable so they all must match

Use good NVMe SSDs. I know someone who put Synology SSDs in the NAS and Plex crashes every day. Take them out and everything’s fine.

WD Black SSDs ( I think that’s their current top-of-line ) are good.
Samsung lost it. Slow and premature failure prone.

Oh dear lol I didn’t configure it right then

I got that unit and loaded it with two 16gb 3200 Mhz DDR4 Memory modules in dual channel and one 2tb Samsung 990 Pro M.2 Gen 4 NVMe SSD

So with the i7-1270p and Intel Iris Xe Graphics I think with 96 EUs on that model I think as memory is in dual channel.

ok. memory is good.

What you should probably consider for the Samsung 990 is a firmware update.

I updated my Samsung NVMe’s too. Sucha PITA. Samsung has fallen far

Good shout !

Just downloaded NVME-CLI and checked and its on the latest firmware thats good news lol!

Can we start a PM at all? One quick Q to ask

You shouldn’t need an hdmi dummy or the uefi ‘display’ function to enable hw transcoding under Ubuntu. You also shouldn’t need them to be able to SSH into Ubuntu server and use the terminal.
