Updated and Optimized Ubuntu Free Graphics Drivers

[oibaf]

oibaf, pardon me if this is a silly question, but how do I override the i915 default driver in order to test i915g? I haven't tried anything yet, but I thought I'd simply have to export MESA_LOADER_DRIVER_OVERRIDE=i915g. I don't see a megadriver hardlink in /lib/x86_64-linux-gnu/dri (I expected to find an i915g_dri.so), which made me wonder if the i915g driver is actually being built. However, looking at the meson.build, it seems the name of the Gallium driver is also i915. Confused.

i915g is not enabled in my PPA. I disabled it years ago because it was broken, see: https://gitlab.freedesktop.org/mesa/mesa/-/issues/669

It got some fixes lately, but I don't know if it can be enabled along i915, IIRC you had to choose i915 or i915g at build time...

I understand. It's been definitely seeing a lot of activity lately (with the push for moving the world to Gallium3D), hence why I'd like to give it a spin. It would be really nice if it could be built alongside the classic i915, it order to give it more exposure (I personally have, from the top of my head, at least three systems where I can test it).

News: panfrost Vulkan driver panvk is now enabled!

News: starting from today build (mesa 21.2~git2107090600.d67712~oibaf~i), I made gallium crocus the default driver over the previous classic i965.
If you find some issue make sure to report it at https://gitlab.freedesktop.org/mesa/mesa/-/issues/new
Enjoy!

I know. The problem is both drivers have the same name (i915), which is downright silly. Oh, well…

[oibaf]

News: from version mesa_21.3~git2107151420.8351ad the i915 classic driver is now replaced by the gallium version. Don't know how much it is working, please test and report any issue at: https://gitlab.freedesktop.org/mesa/mesa/-/issues/new (Labels: i915g)

Ubuntu 20.10/groovy is EOL. The PPA is no longer updated. Make sure to upgrade as soon as possible to 21.04.

Hi all

It looks that there exist a bug in latest in Mesa 21.3.0-devel (git-3e36a20 2021-10-09 focal-oibaf-ppa) when starting a Wine application:

[FONT=monospace][COLOR=#000000]0064:err:winediag:nodrv_CreateWindow Application tried to create a window, but no driver could be loaded. [/COLOR]
0064:err:winediag:nodrv_CreateWindow Unknown error (998).
0064:err:systray:initialize_systray Could not create tray window[/FONT]

This does not occur with stock Ubuntu Mesa 21.0.3. With the stock drivers everything works normally. So there must be somewhere a regression in later 21.3.0-devel builds? I think the first 21.3.0 oibaf releases were running fine. However, I am unsure when this regression was introduced. My GPU is a Radeon 6770M and I am running Kubuntu 20.04 LTS and Wine 6.19 devel.

Just for reference, - it works now again in Mesa 22.0.0-devel (git-ae99ea6 2021-10-14 focal-oibaf-ppa).
