MyGica V2V Pro

[Matthew Barnes]

I have an older Dell workstation with an integrated Intel i865 running
Debian Testing with XOrg 7.6.

Recently I got a MyGica V2V Pro [1] video to VGA converter so I can play
games from an old game console on my LCD monitor.  It has a VGA passthru
so I can switch between my PC and the game console or other video device
device on-the-fly.

However when I boot the machine with this V2V device between the PC and
monitor, I see the BIOS screen flash by and the kernel start to load,
but then when it tries to do a mode switch the monitor goes into power
save mode and never comes back.

When the PC and monitor are connected directly, everything works fine.

Figuring the V2V device is interfering with the intel driver's EDID
probe, I thought if I captured my working configuration and hard-coded
it in /etc/X11/xorg.conf, then the X server would have everything it
needed to know without probing the monitor.

So I ran "Xorg -configure" to get a base xorg.conf and then replaced the
"Monitor" section with the output of "get-edid | parse-edid".  But the
intel driver seem to want to probe EDID regardless.

Attached is my xorg.conf and a diff of two Xorg logs -- one WITH the V2V
device attached and showing failures (-), and another WITHOUT the V2V
device attached and showing normal operation (+).

Hoping for some advice on what I'm doing wrong or what to try next.

Thanks,
Matthew Barnes
