nouveau xorg.conf documentation

nouveau xorg.conf documentation

[Yan Seiner]

I'm trying to get started with nouveau.  I have it compiled, I have it 
installed, but I'm having trouble working out the xorg.conf file.

My system has 3 video cards; one is a single DVI out, two are dual DVI 
out. From the messages in the xorg log files, nouveau expects config for 
DVI-I-0 and DVI-I-1, and so on.  Going from the nvidia blob is not as 
easy as changing nvidia to nouveau; all of the options are different and 
the structure of the file is different.

Can someone who has a working nouveau xorg.conf with multiple cards and 
dual DVI cards please put this on on the wiki?  The wiki is really short 
of info for casual user/developers like me.  My time and knowledge are 
limited so any help I get is greatly appreciated.

Thanks,

--Yan

All randr-1.2+ drivers are incapable of doing the xinerama style
multihead, until someone writes the needed xorg code.

If you want a protocol screen per card, then that should be possible,
minus possible nouveau bugs. Few people actually have a multi card
setup, so a standard config isn't really available.

You can try using this howto
"http://wiki.debian.org/XStrikeForce/HowToRandR12" and expand it to
two (protocol) screens in your xorg.conf

Thats not true, radeon runs fine in Xinerama with other radeons, X
when pciaccess happened
lost the ability to int10 post secondary cards, however if you have a
driver that can post without int10
it should be okay.

you can disable randr have have working Xinerama Intel are just being lazy.

I'm not sure nouveau cares enough to bother implementing zaphod, but
single head might be possible.

I did say randr-1.2 drivers, which implies using randr-1.2, zaphod is
something else altogether, which nouveau doesn't support.

Wierd because radeon in zaphod supports randr 1.2 protocol on both  
protocol screens it only exposes a single crtc and output but all the  
modeset bits are fine. It's only when you introduce xinerama that  
randr needs to turn off and that has 0 to do with randr 1.2 it's  
always been true.
