Under Oneric, where this is working, I did: cat /sys/devices/pci0000:00/0000:00:02.0/0000:05:00.0/drm/card0/card0-DVI-I-1/edid > my_edid.bin
Then copied it to my Precise install in /etc/X11/my_edid.bin
In my Precise /etc/X11/xorg.conf screen section I added: Option "CustomEDID" "VGA-1:/etc/X11/my_edid.bin"
$ grep edid /var/log/Xorg.0.log [ 15.875] (**) NVIDIA(0): Option "CustomEDID" "VGA-1:/etc/X11/my_edid.bin"
It didn't help. Still flickering, the Displays dialog still says "Unknown".
