  generally - why doesn't DRI allow the fullscreen application run in
different depths? It makes sense for 2D (X) and 3D (openGL) to run in
different depth - one example is this HW limitations but I guess there
are other (performance etc.). I mean come on, even windows can do
that:-) [well, in windows I cannot run another graphic shell which I can
use as workaround for this problem:-)]

  what about other cards? any pointers?
