Comment 55 for bug 71593

Fred, i am not sure why the required 3D libs can't be included as dependencies. Do they require 3D acceleration as Desktop Effects (compiz) does, for example ? If no, they should be dependencies. If yes, I'd agree this could use the same mechanism as other non-free stuff uses when proposing to install missing pieces. Overall it makes for a broken end-user experience when it's not there by default, specially if you're offline.
