  • I'm assuming that's the reason my display is garbled after the last update?

The way it works here is a bit different than the radeon gallium PPA: The normal libgl1-mesa-dri contains only the classic mesa drivers. The libgl1-mesa-dri-gallium is an extra, optional package with gallium drivers. The libGL search path is set up so that the gallium drivers are loaded if the -gallium package is installed (Robert's clever idea).

      Note that the -gallium package in xorg-edgers also ship nouveau and intel gallium drivers.
      It would be nice to compile swrastg with llvm support. It needs the --enable-gallium-llvm configure flag and added Build-Depends on libffi-dev and llvm.
      I tested it on my Core Duo and found no regression wrt to classic swrastg, and it is indeed a *lot* faster, as noticed by phoronix articles:

        I had the same, back to classic.

        • It might be even the reason llvmpipe renders garbage as is in this article: http://www.phoronix.com/scan.php?pag...item&px=ODIxMw

          That's the usual price for testing non-stable branches.

            Is there a bug report, where we can track it and see when a fix is available?

            Thanks.

              • Thanks,

                I assume next mesa build will have the fix. I will try the -gallium pack later tonight.

                • I tried latest -gallium pack, it is not a full screen corruption, however, the screen is still showing corruption artifacts.

                  May I ask, gallium is still at v0.4, is there a time frame for official v1.0 release?

                  • I don't think the version really matters, it's just a number, it doesn't mean anything.
