@SeltiX and Jase,
I have the same problem since Lucid, my external monitor works out of
the box but the laptop's display remains black. I use a Sony Vaio S11
laptop with a Nvidia Geforce 310m. I solved the problem in the following
way:
1. I downloaded the 'softmccs.exe'-file, I think form the following URL:
www.entechtaiwan.com/files/softMCCS.exe
2. With that program I made a custom 'EDID.bin'-file for the laptop's display
in Windows.
3. I copied that file to /etc/X11.
4. Then, I customized the xorg.conf in /etc/X11, especially the following 2
lines are necessarily:
Option "ConnectedMonitor" "DFP-0,DFP-2"
Option "CustomEDID" "DFP-0:/etc/X11/EDID.bin"
DFP-0 is the laptop's display, DFP-2 is the external monitor.
5. The rest of the configuration of the xorg.conf, I made in the graphical
interface for the nvidia-driver, especially the settings for
the twin-view-mode.
6. I attach my xorg.conf as it works very good on my system.
I hope, this will help you to make your display work.
Bernhard
