Proxmox 7 Install Intel Iris XE Graphic Driver (1135G7)

[alanch522]

Hi guys,

I'm fairly new to proxmox. The machine is i5-1135G7.

I am planning to setup a plex server with lxc and transcode/decode with iris xe. The CT template is Ubuntu 20.04.
I installed va-api but it seems not compatible with 11gen iris xe.

I followed the instruction and stuck at the beginning : https://ashu.io/blog/media-server-lxc-proxmox/

Problem:
ON HOST I run:
apt install i965-va-driver vainfo
LIBVA_DRIVER_NAME=i965

If I run vainfo it returns:

libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'i965'
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_1_1
libva error: /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so init failed
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

I tried intel-media-driver:

root@pve:~# apt-get install intel-media-va-driver

returns:

root@pve:~# vainfo
error: can't connect to X server!
libva info: VA-API version 1.13.0

libva info: Trying to open /usr/local/lib/dri/i965_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

Has anyone had success with iris xe graphic enabled plex hw transcode/decode in lxc or iGPU passthrough?

driver can not be loaded correctly

i spend 2 week of search for proxmox and passthrough. Check on the forum for intel onboard and 1- forget about this complicated setup. Lxc stuff just give few % diff vs a vm. Start with a normal vm, pass the gfx to a normal os, get a display. then after check for the accelerator. just by itself proper setting to passthrough based on your specific hardw is a challenge and multiple combinaison of setting need to be tested to have it work properly. Just need to be done one, then you will master your system and do more with it later as well.

thank you.
what os do u use as vm now? and what's ur iGPU?

I tried passthrough to windows 10, the graphic not working with code 43. also tried ubuntu, the graphic wouldn't enable hw transcode somehow.
After failing with passthrough iGPU to windows10 and ubuntu, I am working on lxc if there is a possible way.
