nvidia, dual head (no twinview, no xinerama) and gdm

Here is my problem :

I want to do a dual head on a 15" and a 17" monitor with separate workspaces.

Neither Twinview nor Xinerama will do, as they either clone or join the workspaces (as far as I have found), so I go for the good old Xinerama off version. But when I start Ubuntu, I end up with a black screen. If I Ctrl+Alt+F1, sudo /etc/init.d/gdm stop and then startx, I get the correct result, but it's quite a heavy way of launching, isn't it ? Does anyone encounter the same problem or have a solution ?

Here is my config (for the relevant parts) : Laptop, Alienware Area 51m7700, Monitor is a Belinea connected to a DVI port via a DVI/VGA adaptor, graphics card an nVidia GeForce 6800.

Here is my xorg.conf

Thanks in advance for your help.

P.S. : I googled and used search here before posting. If the answer is well known, don't flame me, just give me a link :rolleyes:

My system features a 6600GT with two Monitors connected to it. They are configured as "DualView" (two screens with one Desktop - you can drag a window from one screen to the other).

On boot GDM launches fine.

Here's my Xorg.conf - maybe it'll help you to iron out your problems...

Thanks, but you're doing TwinView here, I was trying a non TwinView, non Xinerama version.

Anyhow, I gave up. I created two xorg.conf, one with TwinView RightOf for work, one with Clone for presentations, and I'll switch with a script. I guess that to do what I really wanted to do, anyhow, the solutions would be to have two separate X sessions, but then I would need two mouses and two keyboards.

Thanks for the help anyhow.

Hi, I have two monitors that require different resolutions. I have tried lots of different versions of xorg.conf. The ctx requires a resolution of 1024x768 while the syncmaster needs 1280x1025.... i can get them both working at 1024x768...

here is my xorg.conf
