Re: debian-6.0.7-amd64 how to set resolution and refresh for free NVIDIA X drivers?

[David Christensen <dpchrist@holgerdanske.com>]

debian-user:

I have an Asus M2NPV-VM motherboard connected to a IOGEAR GCS78 KVM 
connected to a Nokia 445XiPlus monitor.  The system has Debian 6.0.7 
amd64 with the XFCE desktop and the default X driver/server/whatever 
(nouveau).

As configured, the system comes up at 1024x768 @ 60 Hz.  I am unable to 
obtain higher bandwidth resolutions and refresh rates via Debian -> 
System -> Preferences -> Monitors.  If I attempt to provide any 
xorg.conf (including an empty file), nouveau hangs during boot:

If I eliminate the KVM and connect the motherboard directly to a monitor 
(a Nokia 445Xi), the system comes up at 1600x1200 @ 75 Hz (e.g. maximum 
supported by the monitor, the video chip can do more) and I am able to 
obtain numerous low to high bandwidth resolutions and refresh rates via 
the GUI.

Apparently:

1.  The KVM is not passing EDID requests/ responses.

2.  The nouveau driver doesn't support xorg.conf.

I obtain essentially the same results with Debian 7.0.0 amd64.

How do I provide monitor information to nouveau so that the system comes 
up at a chosen high bandwidth resolution/ refresh rate with the KVM 
installed (e.g. no EDID)?

TIA,

David
