This looks like another case (which I hadn't noticed before) of a difference in possible meanings of "default". Some people may read "the default DDX driver" to mean "the DDX driver which will be used unless something tells it to do otherwise". I'm guessing this is how Sven read it. Other people may read it to mean "the DDX driver which will be used in the default case where no better one is available". I'm guessing this is how you intended it. > Since a year or so of server 1.17.0 appearance, the GPU-specific DDX > drivers spend a bare minimum of time installed on the vast majority > of my PCs.

One thing which I haven't been able to make out yet in reading about these modesetting drivers: how well do they work for 3D performance? Or for that matter, high-end 2D, such as you get with Dwarf Fortress? The only positive statements I've found so far, that I recall, are that they work well for 2D acceleration on at least some (if not most) GPU models. If you're using them near-exclusively on most of your PCs, that could imply that they work fine for 3D etc., or simply that you don't tend to need those things on those PCs. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
