Thread: Updated and Optimized Ubuntu Free Graphics Drivers

  1. #841

    Default Llvm 3.4

    I am now providing llvm 3.4-rc2 packages in the PPA, with mesa built against it. Radeonsi users should now get OpenGL 3+ rather than 2.1. Please test.

    Oibaf, what's your policy with non-upstream patches?

    What do you mean exactly? In the past I added some patches (e.g. NV_VDPAU_interop) or merged whole branches before they were merged. I can add something if it can be useful, it has low regression risk and and it isn't too intrusive.

    Currently, I have kubuntu 13.10 and is pleasantly surprised by the improvement of performance.

    ps: I have the default kernel. Do not hurt me change for example 3.13rc? I mean lower temperatures graphics. DPM is still medium terms.

    it would be great to add that for intel drivers if possible. i really miss the vdpau deinterlacing methods in xmc since i switched to intel.

    It looks like one of the changes in the libdrm package actually broke things on my system. I haven't had a ton of time to look into this, but I didn't see anything really indicative of the problem in dmesg, Xorg.0.log, or syslog. Upon upgrading packages though, the system would boot and then hang after adding swap when it switches over to begin starting Xwindows (this is on Ubuntu 13.10, kernel 3.12.2-ck1, Radeon 7870 graphics). Downgrading all libdrm related packages (libdrm2, libdrm-dev, libdrm-radeon, etc.) back down to 2.4.49 appears to work fine even with rest of the packages being updated. I did have previous issues as well where hardware-based rendering would not work, as I have a 7870 and a 7850 in my system (XDM/GDM would start, but after logging it, I'd just get a black screen with graphical corruption and/or a cursor no matter what I'd try), but after claiming the 7850 by pci-stub, hardware-based rendering appears to work fine on the 7870. Currently, with all packages upgraded from your PPA, except libdrm packages as previously mentioned, I'm showing the following:

    root@MainDesktop1:~# glxinfo | grep OpenGL
    OpenGL vendor string: X.Org
    OpenGL renderer string: Gallium 0.4 on AMD PITCAIRN
    OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.1.0-devel (git-79e6512 saucy-oibaf-ppa)
    OpenGL core profile shading language version string: 1.40
    OpenGL core profile context flags: (none)
    OpenGL core profile extensions:
    OpenGL version string: 3.0 Mesa 10.1.0-devel (git-79e6512 saucy-oibaf-ppa)
    OpenGL shading language version string: 1.30
    OpenGL context flags: (none)
    OpenGL extensions:


    Not sure if anybody else experienced issues wth the upgrade to libdrm 2.4.50, but figured I'd throw this out there. I should have time this weekend to assist with additional troubleshooting if needed.

    It breaks XBMC, white screen when I try to play any video.

    Latest update broke something, cause as soon as my Mint 16 Kernel 3.13 R3 boots, the screen freezes. Have to get in with software rendering. Radeon HD 4250 with HD 5470 hyrid laptop.
