Updated and Optimized Ubuntu Free Graphics Drivers

[oibaf]

Hi,
also do you plan enabling new "rusticl" OpenCL 3.0 driver on oibaf builds?
(https://www.phoronix.com/news/Mesa-22.3-Rusticl-Merged) seems supports even images, never supported by Clover..

Maybe next month.

Okay, thanks for the hint. Yes I see now, package va-driver-all 2.14.0-1 is installed but when I run vainfo libva 2.12.0 is declared.

So in the end this means that VA-API version 1.14 contains libva 2.12.0, - really confusing. Whatever, in this case I have just to wait until the va-driver-all package is updated by Ubuntu.

Probably the vainfo tool was built against libva 2.12 and the version string at built time was recorded, I don't think it matters...

For the new year here follows now a short emergency help for the case that a faulty Mesa driver will break the system. Maybe this could be added at the oibaf PPA main page.

Okay, I ended up with a broken system and the steps to switch back to stock main Mesa was in my case:

Add the number 3, xforcevesa and eventually vga=791 to the boot parameters. So this will give:

quiet splash 3 xforcevesa vga=791

After that it should be possible to boot directly to the command prompt (CLI). Login with username and password and then execute the ppa-purge command:

sudo ppa-purge ppa:oibaf/graphics-drivers

Note, do NOT try this at the emergency console! This will not work and it will make the situation even worse. For a proper restore of stock Ubuntu Mesa an internet connection is necessary. Unfortunately ppa-purge is trying to purge the PPA also in offline mode which leads to a bigger mess in the way that some stuff is removed while the original stock Mesa is not restored. So don't try this when no Internet connection is present at OS level! Maybe that information should be also added at the oibaf PPA page.
