Agreed, DirectFB still looks promising. Also, I suspect the issue might not
lie with Qt, but with Mythtv. The only hint I found through googling was
an identical error sequence where the solution came from "Are you sure
you have a definition of each non-pure virtual function. In particular
check the first non-inline non-pure virtual function of <class name>.
The compiler uses that (if it exists) as a key. It will emit the vtable,
typeinfo and other class related objects in the object file containing
that key". My last serious encounter with C++ was about 1995, so I _am_
guessing. Tracking that sort of issue through Mythtv and/or Qt is beyond

I'm interested. I've seen some recommendations, but if your collection is
easy for you to gather, I would appreciate a look.

Yep, I noticed.

Cool, I'll take a look at qte-directfb. And on the matrox thing - mine's
an old G450 that I simply refuse to give up.
