Twinview with nouveau and without EDID

[kto]

Hi guys.
I am currently trying to get two monitors working together. One is a 22" LG Flatron L227WTP which is working fine (I am currently using this one) and an older 22" Hanns.G Hi221D which does not send proper EDID (or none at all) and is constantly shown as "disconnected", although it isnt.
I tried to use xrandr to set up these monitors for twinview, but, as I just said, the Hanns.G just doesn't want to display anything.

$ xrandr -q
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192
DVI-I-0 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 296mm
   1680x1050      59.9*+   60.0  
   1280x1024      75.0     60.0  
   1440x900       59.9  
   1280x960       60.0  
   1152x864       75.0  
   1024x768       75.1     60.0  
   832x624        74.6  
   800x600        75.0     60.3     56.2  
   640x480        75.0     60.0  
   720x400        70.1  
DVI-I-1 disconnected (normal left inverted right x axis y axis)

I tried to add a modeline for the second monitor, but it still does not react.

I also tried to generate a new xorg.conf using

$ Xorg -configure :1

and then edit it to use a custom EDID-file which I got frome the LG and to use twinview, but I get something like this

...
(WW) NOUVEAU(0): Option "TwinView" is not used
(WW) NOUVEAU(0): Option "TwinViewOrientation" is not used
(WW) NOUVEAU(0): Option "CustomEDID" is not used

You can find my xorg.conf file here.
What did I do wrong? I am willing to try just about anything

As I said, I would try anything, so please help me. I don't want to throw away this basically working monitor and buy a new one just because I am unable to configure it right.

Until it gets recognized the other monitor is useless.

You can try plugin it in in another port on your video board.

nvidia-xconfig --no-use-edid

It is using the EDID of the monitor or it wouldn't be named DVI

"twinview" is nvidia's proprietary name for a very standard thing.
You aren't using nvidia's proprietary driver, hence nvidia proprietary nonsense won't be recognized.

You are using nouveau. That is the open source driver.
Nouveau is the product of REVERSE ENGINEERING. It may or may not work in any particular circumstances.

You can try using STANDARD X STUFF to configure your multiple monitors. You can add MODELINES into your xorg.conf to match the monitor with bad EDID. The two key points of information regarding configuring that thing is "man nouveau", and "man xorg.conf".


Alternatively, you can try using nvidia's proprietary drivers, though in my experience, they're usually quite broken.

Oh! ignore my post, it won't work you don't have nvidia-xconfig installed sorry.

Still you got a problem there with the monitor not being recognized, and that will not enable you to do any configuring until you get the system to see that monitor connected.

If twinview doesn't have support on nouveau you can try using xinerama they are two different things that do the same things.
