Hi,
i use a gentoo distribution and i see that after release of the nouveau kernel
driver v. 20110602 (with both kernel 3.x and 2.6.x) dual head doesn't work.
I have a NVIDIA Quadro FX 2800M.

01:00.0 VGA compatible controller: nVidia Corporation G92 [Quadro FX 2800M]
(rev a2

So, with version 20110801 and 20110820 there is a regression that doesn't
permit correct use of dual head.

Currently, i use xorg-server-1.10.3 (i try soon 1.11.0) but i don't think that
problem is on xorg-server.

So,now i downgrade version on kernel module to 20110602 and all works fine.
Please, can you verify where is regression?

As x11 driver i use v. 0.0.16_pre20110323.

Thanks

P.S. If it is needed i will upgrade soon a dump of the xorg.log when dual head
doesn't work.
