BES is only available on CRTC1, it's a hardware limitation. dfbmga uses the texture engine to scale the video. Technically XDirectFB could do the same thing for Xv but no one has implemented it. > Sorry if I'm going a bit off topic, but what would be the best method to > do what I want (accelerated TVout)? > I've read that the Matrox G400 is more flexible and that it's possible to > swap heads on this card.

If you want Xv your only choices are the Xorg mga driver or XDirectFB. AFAIK the Xorg mga driver's binary mga_hal module doesn't work with recent Xorg releases so TV-out won't work. Also I don't think the Xorg driver ever supported swapping the heads so Xv on the TV-out is not possible. If you have a G400 you could drive the TV-out with matroxfb and swap the heads with matroxset (I don't remember the exact incantation anymore) and use XDirectFB. You will probably have to tweak the video timings with fbset to get a decent picture out of it though. -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ _______________________________________________ directfb-users mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
