Hi Vladimir, I have the same configuration, but I failed as well enabling three head output. Seems that the card only supports two simultaneous heads. BTW, do you also observe the strange artefacts I'm observing when using radeonhd on your Laptop? I'm referring to this post: http://lists.opensuse.org/radeonhd/2008-03/msg00234.html Cheers, Michael On Freitag 28 März 2008, Vladimir Grebenschikov wrote:
Hi
Is it possible to configure 3-head installation with following card ? I have IBM T60 with dock, so there is two ports on dock (DVI + VGA) and LCD Panel.
I've tried to configure third monitor, but in best case I've get two monitors and third duplicating one other.
