Updated and Optimized Ubuntu Free Graphics Drivers

[Javimixet]

Hi all.
I've been using the oibaf ppa since august of last year when, after upgrading Lubuntu 15.10 to 16.04 and Blender, the last stopped working with this message "Error! Blender requires OpenGL 2.1 to run. Try updating your drivers.", which was solved by adding the repository and upgrading. THANKS!!! ^_^
The past Friday I made an apt upgrade and blender stopped working again, now with this message "Writing: /tmp/blender.crash.txt Segmentation fault (core dumped)". Also noticed mpv, only when started in fullscreen, gives also a segfault with this info in dmesg "mpv/vo[18230]: segfault at 234 ip 00007ff625ed96e8 sp 00007ff6277fd7b0 error 4 in i915_dri.so[7ff6259f5000+9c8000]".
I've purged the ppa and tried with the paulo-miguel-dias ppa with the same results.
The previous upgrade was from 2017-02-06 (17.0~git1701100730.17eac3~gd~x, 17.1~git1702040730.106a51~gd~x) and worked. Is there a way to downgrade to that version without compiling?

Hi again.
I ended compiling, opening a bug and tracking for the the commit that caused it.

https://bugs.freedesktop.org/show_bug.cgi?id=100189

The gallium i915 is unmantained and in deprecation period.
In my eeepc 1005p lubuntu 16.04 when I install drivers from the Oibaf repo this driver installs as default and the one in the alternative folder is different (can't use it with the last version of Blender) that the one I get when compiling:

Oibaf
LIBGL_DRIVERS_PATH=/usr/lib/x86_64-linux-gnu/dri-alternates/ glxinfo | grep OpenGL
OpenGL renderer string: Mesa DRI Intel(R) Pineview M
OpenGL version string: 1.4 Mesa 17.1.0-devel

Compiled
LIBGL_DRIVERS_PATH=/home/javi/lib.106a514/ glxinfo | grep "OpenGL version"
OpenGL renderer string: Mesa DRI Intel(R) Pineview M
OpenGL version string: 2.1 Mesa 17.1.0-devel (git-106a514)

Thanks, I'll have a look, likely making classic driver the default as soon as i have time (weeks).

H.L. was very helpful and sent me a patch adding vulkan drivers (mesa-vulkan-drivers) and a dedicated va package (mesa-va-drivers). I added it to the mesa package. Enjoy!

Hi, Approximately a couple of weeks ago, the driver stopped working correctly. In the game Worldofwarcraft and Worddoftanks watch bands (colored)
I believed that the problem with me and performed the reinstallation of the system. Re-used your repository, but the problem did not resolve

Hi, I've been using your repository for a very long time and a couple of weeks ago there was a problem (see the video, the bands are colored). In my opinion, there was an update. I can not play now.
