The same warning? Then DRI doesn't work for you either. Is there _anybody_ who has DRI working on RELENG_7 with the intel driver and i915 graphics hardware? I'm really starting to regret I updated this machine at all. Another case of "never change a running system". :-( > I've not noticed any problems related to this > warning, and I also have seen this for my nvidia based linux box.
