libva fails to load intel driver on 18.04 : undefined symbol: wl_drm_interface

[rougebuntu]

Ubuntu 18.04.04

VA-API fails to load, leading to hardware acceleration not working in chromium
This causes applications using the engine to become extremely laggy and utilise 90% + CPU.

This is a VERY common use case for ubuntu users and needs to be patched as a priority IMO

Appears to have been inherited from Disco and is the same bug or similar as here:
https://bugs.launchpad.net/ubuntu/+source/intel-vaapi-driver/+bug/1813131

Current driver:
i965-va-driver/bionic,now 2.1.0-0ubuntu1 amd64 [installed]

Bugfix candidate: (about to try compiling from source)
https://launchpad.net/ubuntu/+source/intel-vaapi-driver/2.3.0-0ubuntu2

Further issue report here:
https://github.com/intel/intel-vaapi-driver/issues/419

output from vainfo

apt install i965-va-driver

i965-va-driver is already the newest version (2.1.0-0ubuntu1).
0 to upgrade, 0 to newly install, 0 to remove and 2 not to upgrade.

apt search i965-va-driver:

  VAAPI driver for Intel G45 & HD Graphics family

Just tried build:
https://launchpad.net/ubuntu/+source/intel-vaapi-driver/2.3.0-0ubuntu2

had to install dependencies of:
sudo apt-get install libva-dev

Appears to be the same issue present in current vaapi driver.

I'm going to try a later version, perhaps 2.4.0

[rougebuntu (rougebuntu)]

for some reason i thought i had used sudo. Evidently not.

see: PermissionError: [Errno 13] Permission denied: '/usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so'

Anyway 2.3.0 did install successfully, but vainfo shows no change

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Michel-Ekimia (michel.ekimia)]

What Intel hardware do you have ? Comet lake ?

Because I could not reproduce on :

- Haswell
- Skylake

But could on Comet lake
