That clearly represents that no monitor is connected. I just tried it and it looks like it works. The output of vglrun: 1984 frames in 5.0 seconds = 396.682 FPS 2285 frames in 5.0 seconds = 456.836 FPS 2300 frames in 5.0 seconds = 459.870 FPS While a normal glxgears run is synchronized to vertical refresh. But the Xorg and glxgears are using a whole lot of cpu time. Even after glxgears exits, X still uses 100% of one core. Actually, my laptop has a hdmi output which seems to be connected to the NVidia card. I hope that I can use it in the same X server with other screens (internal / vga output), and have some 3d acceleration. > Thanks! > > > -adrian > _______________________________________________ > freebsd-mobile@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-mobile > To unsubscribe, send any mail to "freebsd-mobile-unsubscribe@freebsd.org" > -- Cheers, Henry
