xorg-server 1.5 and TwinView, wrong resolution in big monitor

I have a TwinView setup with a 1280x800 laptop screen and a 1280x1024 19'' monitor.

Before upgrading to xorg-server 1.5 it worked fine, with both monitors at their correct resolution. Now, the laptop screen resolution is fine but the big monitor resolution is wrong, smaller than usual. In nvidia-settings I can only select 1379x768, 1152x864, 1027x768, etc.

Is this a known problem? Any known solution? I've already tried with the last two beta versions of the nvidia driver, and resetting xorg configuration to the minimum with nvidia-xconfig, without any change.

However, this is my current xorg.conf:

Section "ServerLayout"                   
    Identifier     "Xorg Configured"     
    Screen         "Screen0"

    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Touchpad" "SendCoreEvents"
    InputDevice    "USB Mouse" "SendCoreEvents"
EndSection

Re: xorg-server 1.5 and TwinView, wrong resolution in big monitor

Makes sense, you're using a custom EDID. Where did you get the info to use it? I could try with that while they don't fix this...

Re: xorg-server 1.5 and TwinView, wrong resolution in big monitor

However with your config file (commenting the edid line out) only my laptop monitor turns on. Also, I just realized my external monitor is reported as "CTR-0" instead of "Benq FP91G+" in nvidia-settings like before, so I guess changing the EDID would solve it.

Re: xorg-server 1.5 and TwinView, wrong resolution in big monitor

Well, confirmed that there was an EDID problem, I solved it booting in Windows, running Phoenix EDID Designer and exporting the EDID of my big monitor in .raw format, and then adding the following line to the Device section of my xorg.conf:

Option         "CustomEDID" "CRT-0:/mnt/sda1/Stuff/bnq.raw"
