Bugs are never expected, but are uncommon either... > Can I do something to use the new video card with the new motherboard? Try running a recent snapshot. There where some bug fixes regarding pci bridges since 4.5 iirc. Also, the Xorg.0.log and the output of pcidump -v for the new video card could give some of us better clues, especially if the card still doen't work in X with -current. -- Matthieu Herrb
