Updated and Optimized Ubuntu Free Graphics Drivers

[johnny99]

This is not fixing i386 build, I build 3.7.1-rc1 but it still breaks.

That's unfortunate. Any idea what is causing the failure?

[johnny99]

Looked at your build log. Not sure but can you limit the buildbot to building for i386 and x64? Some of the fail look like they are for ARM and Apple.

glxinfo | grep render
direct rendering: Yes
    GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer, 
    GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer, 
OpenGL renderer string: Gallium 0.4 on AMD TURKS (DRM 2.43.0, LLVM 3.6.2)
    GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth, 
    GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_packed_depth_stencil, 
    GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth, 
    GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_fog_distance, 
    GL_OES_element_index_uint, GL_OES_fbo_render_mipmap,

I have somethink like this. So I'm using GPU or not?
In chrome://gpu i have:

Video Decode: Software only, hardware acceleration unavailable

yes you have GPU BUT video decode is disabled in chrome by default. if you want to use vdpau or vaapi you need to compile chromium yourself or find a ppa that provides that functionality.

Any estimated time when we can have newer compiler? It's getting really frustrating to wait. Padoka ppa doesnt work for linux mint?

When Ubuntu will provide an llvm that properly build on i386.

Is someone working on providing it? Is there anyway to impact this process? Or track it? Have they been fast with similar processes before?

I just contacted ubuntu mailing list. I just opened my email and I got this reply.


Hi, the package was never built on i386, so I didn't put much effort in fixing it. thanks to your mail I speeded up the task in my todolist, and cooked a patch against llvm-3.7. I'm not sure mesa stuff should work this way (being broken on amd64 because of a missing i386 compiler seems somewhat strange, but I don't want to investigate the rationale behind this). I updated with a patch the bug that Robie opened on llvm-3.7 https://bugs.launchpad.net/ubuntu/+s...7/+bug/1527865 I basically disable the LLDB testsuite on i386, because seems that the buildd system hangs with it and gets killed after 150 minutes of inactivity. We already have it disabled for some arm* architectures, so even if it isn't a good solution (and probably there is a bug against i686, because the same build on Debian i386 works). Not sure, but at least it has been built successfully. cheers,

Thanks, once the bug is fixed I'll upload to the ppa.

For end year holiday I uploaded to wily ppa some recent releases of open source games: 0ad 0.0.19, supertux 0.4.0, supertuxkart 0.9.1.
