    Phoronix: Easily Test Driving Gallium3D In Ubuntu 10.04

    If you have been wanting to test drive the Gallium3D drivers on your new Ubuntu 10.04 LTS "Lucid Lynx" installation but have been put off by the idea of building the Mesa stack yourself, fear not any longer. There's some new packages in the Ubuntu xorg-edgers PPA for easily facilitating the switch from classic Mesa to Gallium3D for Intel, ATI, and NVIDIA hardware...

    Last time I checked Ubuntu 10.04 wasn't released yet

        but it's almost here.

        some people have already upgraded to beta/rc and keep it running already.

        it's not like it only becomes available on the day of announcement.

          At the moment it's broken. Whenever they update the kernel image, it takes a while before the new xorg-edgers packages are available. Your old kernel will still have 3D though.

            The PPA has a kernel image (and it's even required if you plan to use the nouveau driver). If you are willing to run bleeding edge X, you may as well go all the way and grab the bleeding edge kernel as well.

              Please read the notes on the xorg-edgers page if you are using it, it explains what happened.

              You need to install a 2.6.34+ kernel to use nouveau with xorg-edgers because there is no more of the linux-backports-modules-nouveau mess causing the problems you described. There is a kernel in the PPA as well as links to more current ones on the page.

                Will these drivers offer Wine 3D support?

                  The only thing I care about in a GPU is 2D support and video codec acceleration. Right now running the Nvidia blob I get VDPAU which works great with mplayer/ffmpeg/XBMC. These 3D science projects may be fun for gamers but they don't do anything for regular users.

                    Im consider myself a linux newb, and i think its great to finally see a "easy" method for enabling Gallium3D, i may just try it out.

                    My notebook:

                    HP Compaq nw8440
                    Intel C2D T7400
                    ATI Mobility Radeon X1600

                    As of now i use Windows 7 since i need at least some 3D acceleration, but ATI Legacy drivers are unsupported (crap) and i really like poking around with Ubuntu.
                    So this is great news.

                      Does this Gallium3D better than the official nVidia driver in watching HD h.264 movies (720p , 1080i) ? because when I watch movies on my nVdia 6200 LE its kind of eats all of my CPU usage !!

                        I don't think it implements accelerated video decoding. But I can watch 720p video on my single core Athlon 64 4000+, so most probably the driver does implement Xv.

                          Only Dx10 class gpus can do full H.264 hardware decoding if im not mistaken.
                          With cpu decoding i can play 1080p in Windows 7, but with Ubuntu 10.04 i only get stutter with the same clip.

                            Try using a multithreaded decoder, like mplayer-mt. Or buy the CoreAVC codec. Both will perform much better than the default that comes with most distros.

                              It depends on how the acceleration is implemented. For example, any card can decode H.264 if it has dedicated H.264 decoding hardware. Alternatively, the H.264 decoding can be implemented by using the GPU as a general-purpose massively-multithreaded vector processor. That can be done on any NVIDIA GPU starting with the GeForce 8 series. I don't know what the cutoff is for ATI. The Intel X4500HD chipset has H.264 decoding support (and will get Linux support for it soon), and I think GMA 965 and later GPUs have some support for VC-1, too, but it's not full decoding support, and it's not available under Linux.
