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
1024x768 75.1 60.0
800x600 75.0 60.3 56.2
640x480 75.0 60.0
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
