While I consider these just "fun demos" at this time, it seems that the future of desktop environment will require working DRI. I've tried e.g. the GnomeShell 2.28 package currently in Debian "Squeeze" Testing, and it's completely unusable at this time. Since GnomeShell (http://live.gnome.org/GnomeShell) appears to be the default environment in the GNOME 3.0 release, it would be nice if I can help fix DRI on Itanium by September 2010. > I think there are two ways we can make progress: > > =A01) Try to convince DRM folks to help debug this. > > =A02) Use git bisect[1] between v2.6.29 and v2.6.30. =A0This looks like > =A0 =A0 about 13 kernel rebuild/test cycles. =A0I don't see the stable > =A0 =A0 releases like 2.6.29.6 in the git repo, but you won't lose much > =A0 =A0 by starting with 2.6.29. I'll try the git bisect route first, and then ask for help when I have the bad commit identified. Emeric
