Trying to enable hardware transcoding by following this guide but the /dev/dri directory does not exist. I've tried modprobe i915 in the console with no luck. Pretty much ran out of forum posts to look at too

 

EDIT: also looked through these instructions but I was not able to add /dev/dri to the PMS directory

 

Plex dash says it's not hw transcoding and I believe iGPU should be enabled in the BIOS. I'm using an HDMI monitor connected to my mobo with no GPU. Oh, and yes, I have Plex Pass.

 

Using an MSI Z790 motherboard.

typo

Been troubleshooting this problem and somehow got /dev/dri to show up after a reboot... but then the plex docker froze after adding the directory and I had to reboot again. Back to missing /dev/dri again lol. Setting up this server has been a game of tech wack-a-mole 🤪

 

EDIT: Having really weird issues now. Half the time I reboot, I see the screen freeze around the Samba settings but it still goes online. When it does, I can terminal into the /dev/dri folder on my other PC but the system gets all unstable and sometimes can't shut down properly. I've been getting freezes and all sorts of weird behavior.

You are using 6.10.3 and the i915 is blacklisted. Install intel_gpu_top from CA so it loads the driver correctly. Or you need to add the force probe to i915 in modprobe.d on the boot drive.

When I initially created a boot usb, the server would hang at i915 initialization on versions newer than 6.10.3. I wasn't able to access the terminal and had no experience with unRaid so I rolled back. Should I try updating?

 

intel_gpu_top hasn't been working for me. GPU statistics doesn't show any info for my graphics either. Can you elaborate on how to force i915 in modprobe.d?

You need to edit this file. currently it has blacklist i915. I dont know what the value would be for your CPU. But it should be in the system log when the driver loads currently it is set not to load.

 

root@computenode:~# cat /boot/config/modprobe.d/i915.conf 
options i915 force_probe=56a0
root@computenode:~#

That seemed to reveal /dev/dri !  Thank you so much!

 

However, it looks like there's still some issues. After adding the directory to plex, the server doesn't play any video on any device. Also, I noticed that the screen hooked up to the unraid server froze at fb0: switching to i915 from VGA. 😔Eventually this thing will work..

 

Can't shut down gracefully again

It looks like there is some problem with the video card driver after adding the directory to the Plex server.

I updated to 6.12.3 and everything just worked! Hooray!

sometimes it helps to add an HDMI dummy plug into the Mainboard Slot. 

Hello all, I seem to be having the same issue here.  I'm trying to get HW transcoding working on my plex server.  None of the forums, videos and FB posts have yielded any success.  I've only been using Unraid since this past spring.  I migrated over from windows.  I really don't want to go back but if I can't get this working, I may not have a choice.  My hardware is an Asus Prime z590-p MB, Intel I7 10700k cpu, 32gb ram, LSI sas card with 9x SAS 8tb HDDs and 2x 2tb Samsung Evo SSDs for cache.  I noticed the other day when watching an HEVC movie on my Iphone, my CPU was maxing out.  I went over to my Plex DB and noticed it wasn't HW transcoding.  

 

First I tried to put in the /dev/dri device path in my plex container.  That just made my plex error out.  Then I installed intel gpu top from the app tab.  That made no difference.  When I run intel-gpu-top from terminal it returns "No device filter specified and no discrete/integrated i915 devices found".  When I try to navigate to cd /dev/dri, it returns "bash: cd: /dev/dri: No such file or directory".  I have gone into my MB bios and made sure the gpu is set to on board, Igpu or what ever you want to call it and not auto, PCIe or PEG.  I enabled mulit monitor in bios per another recommendation.  I did have an HDMI dummy plug installed but I took it out and reconnected my monitor just for giggles.  I have uninstalled and reinstalled intel gpu top app and rebooted several times.  I do have a plex pass.  In an early post from last week, posted above, one user was telling another to make changes to "/boot/config/modprobe.d/i915.conf" but I try to navigate to that in terminal it returns "/boot/config/modprobe.d/i915.conf: No such file or directory". 

 

I'm at a total loss and getting a little desperate.  I've also posted this on Unraid FB help page as well and none of their recommendations made any difference.  Can someone please help a noob before I have to suck it up and move back to Windows???  I really don't want to do that.  Thank you in advance.

Maybe try doing this command and see if that creates the file?

modprobe i915

 

Otherwise, I guess you could try creating it yourself. Add to the file 'options i915 force_probe=56a0' and reboot. In my system logs, I searched for 'force_probe' and it gave me my cpu code which I used to replace the 56a0 value. It didn't fully work at first but then I updated to 6.12.3 and everything started working

So I installed the intel_gpu_top to test if Jellyfin is using hardware transcoding. But when I run the gpu top command I get the error message "No device filter specified and no discrete/integrated i915 devices found". I ran the cat command you posted here and there is not a i915.conf file. Is this something I need to create? If so, what should be inside?

Try cpu also do you have a physical gpu in system or just igpu?

No physical gpu. I will try cpu.

 

Also, when I go to system drivers in unraid and search for gpu, i see the intel i915 inuse. See screenshot.

Have a look at this tread I think you need to enable multi monitor.

I've enabled iGPU multi-monitor and changed the display in the BIOS from Auto to CPU. I can now see the iGPU. I still don't get any results when I run the intel_gpu_top command.

 

I also unplugged my monitor just to be safe.

@SimonF

 

so I tried running modprobe i915 like @akimboflix above said and nothing happens. I had to ctrl+c in the terminal to regain control. I tried creating the file as well and rebooted. Then I saw this message in the syslogs "Setting dangerous option force_probe - tainting kernel", so I deleted the file.

Can you post diagnostics
