I have a dual head video card which is has two identical monitors attached.
Nvidia settings finds only one monitor correctly and the other a much lower resolution unknown type.
What to do I need to change in nvidia-xconfig to have both screens in the same (1440x900) resolution
This problem only started with the update to with Gnome 3 .
The X.Org X server -- Nouveau
display drivers were removed by Gnome 3 so I had to switch to the nvidia-glx (173.xx)
I know this is not really a Mint issue but I can not finding anything on-line yet, that doesn't leave me with with a black screen or just just a text log in !
For the record I'm using LMDE 32 with all 5 levels updated and it's a clean install with only chrome, cheese and webcamstudio as added apps.
