I have a Revo running Pre-Eden updated from the default XBMC-Live-Dharma install.

If I have my amp/tv turned to the correct inputs it'll have no problems starting up, but if they're on different inputs it refuses to start (don't think I've had this problem before, but might have never tried to start it without the screen being on the right channel).

I've read that if I create a custom EDID file in /etc/X11 and point the xorg.conf to it that'll it'll use that if it can't find the monitor. Has anyone got any idea of what kinda format this should be in? I've searched all over the place but can't find an example.

If I run:

Code:
sudo get-edid | sudo parse-edid

I get this (when amp is connected and XBMC Live is working):

Code:
parse-edid: parse-edid version 2.0.0

get-edid: get-edid version 2.0.0

How should I use that to create my own EDID to point to in xorg.conf? And is the error anything to worry about?

Thanks for any help

Hi Christian,

I had your problem too and solved following the instructions on these posts:

I tried also the route of the custom EDID, but actually is much more complicated.
Just find your perfect resolution parameters and then just create a new Xorg.conf.
As an example, here is my Xorg.conf file attached that works without a monitor attached.

For me worked perfectly.

Code:

Thanks man, I'll check this out tonight.

Ok. Please come back with the result Smile

Well to answer your main question, the file needs to be raw EDID data stored in a file.

So what your probably looking to do is:

Code:
sudo get-edid > filename.bin

parse-edid, according to the man pages i'm reading, is used to make the data human readable. Which is useful if you want to know more about the settings your monitor is capable of, but not so useful if you want the data to work as an Xorg EDID file.

I currently use the CustomEDID option with my setup, as well as manual settings. I'm configured the the point that i probably dont need the EDID file anymore and having both is probably overkill, but i like knowing that the driver has all the information about the connected monitor and will play nice if i forget to set something. If your curious what my Xorg settings look like, i've attached the important sections below.

Also, if you run the X server with "-verbose 6", it should spit out all the information you need to configure your Modelines and settings in the log file. (File: /var/log/Xorg.0.log)
