Updated and Optimized Ubuntu Free Graphics Drivers

[Vanek]

Hi oibaf. Could you please add this patch WIP: st/vl, st/vdpau: motion adaptive deinterlacer to your builds?

[oibaf]

@Doctor Nick: there are bugs with llvm 3.5 ( https://bugs.freedesktop.org/show_bug.cgi?id=70410 ), I prefer not to use it until it's stabilized to avoiding build failures.

@sacrediou: try purging the PPA, make sure to check all PPA packages are removed and then reinstall it, it may be that some older packages are still installed that may conflicts.

@Vanek: I could do, but is that patch still being developed by someone or it was abandoned (it's 3 months old)? Was it publicly discussed somewhere?

i guess it's in "testing state" since that time

Was it publicly discussed somewhere?

Well, I've found

but xbmc guys are using it now http://forum.xbmc.org/showthread.php?tid=174854

Ok, that's reasonable. Still, I think I'd like to see an llvm daily repo for the mesa drivers, since OpenCL support is going to continue to evolve rapidly (AMD is committing full-time developers to it now).

I'm thinking of creating my own PPA, where I import the oibaf source packages, patch the debian control files, and recompile them. Does anyone know how to set up an automatic build thing like this?

Switching is done automatically on 3.13 and newer. The dGPU is automatically powered down when not in use. You can get the old manual behaviour back by booting with radeon.runpm=0 on the kernel command line in grub.

this does not work proper on my notebook: black screen after " sudo restart lightdm"
vgaswitcheroo was the only way to play my games, AMD Catalyst does not install, VirtualGL is too complicated for me.

-edit-
I solved using DRI_PRIME=1

I apologize for my ignorance but this new function is not described in the guides and forums in Italian.
DRI_PRIME works fine!

undefined symbol in r600_dri.so

Hi all,

After running
LIBGL_DEBUG=verbose glxinfo
I can see this error:

libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/r600_dri.so
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/r600_dri.so
libGL: driver does not expose __driDriverGetExtensions_r600(): /usr/lib/x86_64-linux-gnu/dri/r600_dri.so: undefined symbol: __driDriverGetExtensions_r600

Other information in this debug command I think is all ok:
http://pastebin.com/3U2jCwSQ

ppa-purge removes this error but when I reinstall the graphics driver, it appears again.

My graphics card is a Hd4670 agp, and apparently, the graphics driver works well. At least I have not noticed any problems with it.


Regards.

This is expected and it's not an error, it's just that gallium drivers don't support megadrivers.

I added the patch to the PPA (on both 13.10 and 14.04). Please test.

Hello oibaf, are you planning to enable openmax in your builds for testing?
Thanks!
