Ahoj, prosím o radu.

Systém je Ubuntu 22.04, poslední aktualizace (apt upgrade).

Linux test 5.15.0-56-generic #62-Ubuntu SMP Tue Nov 22 19:54:14 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

V PC je integrovaná Intel GPU, tedy UHD Graphics 770 "8086:4690", ale tato zdá se nefunguje. V lspci je sice vidět, ale nevytvoří se mi potřebné /dev/dri/ zařízení (adresář /dev/dri zcela chybí).

Takže mi nefunguje např.

~# intel_gpu_top
No device filter specified and no discrete/integrated i915 devices found

A kartu nemůžu ani použít pro rendering třeba ffmpegem (přes VAAPI či QSV).

Podle tohoto podpora této konkrétní karty má být https://cateee.net/lkddb/web-lkddb/DRM_I915.html

Modul je, zdá se, zaveden...

Kde může být, prosím, problém? Zkusil jsem přeinstalovat přes apt balíčky kernelu, modules, extra, ale nic nepomáhá. Jinak se jedná v podstatě o čistou instalaci. Přítomna je ještě druhá GPU v PCIe (NVIDIA), na které NVENC sice funguje, nicméně /dev/dri také nevytváří (na jiném stroji stejná karta ale ano).

Děkuji.
