TwinView shows wrong (non-native) resolution on second DFP

[nw_biohazard]

I'm trying to set up X to mirror the bottom portion my primary display (Dell 2407FP, 1920x1200) on a Sharp LC-32D62U (1920x1080). I created custom EDID files using nvidia-settings and pointed my xorg.conf file at them (See below). The Dell screen is perfect. The display on the Sharp screen appears to be scaled a bit in both "x" and "y" but clipped in both dimensions.

I'm not sure this is relevant, but on boot, the terminal window is also truncated on the second display.

Any clues?

You can only have one value for an option in xorg.conf. In this case, it's getting this one:

(**) NVIDIA(0): Option "CustomEDID" "DFP-0:/etc/X11/Dell_edid.bin"

If you want it to use both, you need to use a single option with the syntax documented in the README, with semicolons between declarations.

Changed to this:

Option "CustomEDID" "DFP-0:/etc/X11/Dell_edid.bin; DFP-1:/etc/X11/Sharp_edid.bin"

Same result on the second screen.

Did you ever get your "CustomEDID" to work?

So far I've not been able to get mine to work.

Thanks!
