Linux HOW-TO setup XBMC and Linux with correct resolution (xorg.conf)

Heya,

I'm having trouble locating the xorg.conf...

I installed XBMC from the LiveCD.
/etc/X11/xorg.conf does not exist, neither any file called "xorg.conf" (checked using find / | grep "xorg\.conf")

follow the instructions on first post please for xbmclive install.

I would, but I cant since xorg.conf does not exist altho XBMC is able to change the resolution via "settings"....

all I need to know is the path to XBMC's xorg.conf...

currently I'm trying to find a workaround with xrandr and xauth... works but the smaller screen is flickering and cuts the output... or basicly it doest seem to bother resizing the output of XBMC....

you dont need one to exits to create one, IF you follow the instructions one will be created for you, no need for workarounds or hack jobs...

suit yourself.

Snaek what video card do you have?

If you have an Nvidia card the type this at the command line:

EDID is not supported on VGA cable.

Any way i can get a decent resolution like 1280x800 or 720 over VGA? I have Dell Inspiron 6400 E1505 with Nvidia GeForce Go 7300 and Westinghouse 42" TV with 1920x1080p Full HD native resolution.

Thanks.

After trying for hours, I'm giving up! Maybe someone knows the reason, why I can't get 1080i or 1080p running with CrystalHD@ATV1?

Following above guide, xlog.txt states that my display does not support such resolutions. But actually it does!
- http://www.sony.co.uk/product/tv-66-26-l...nicalSpecs
- I have a satellite recv. also connected to the 2nd HDMI-port and the TV confirms 1080i.

Assuming this is a mistake from Sony, I tried to override the settings in xorg.conf, with no luck yet!

Also, hoping not to need the "updated Crystal-drivers", since I need audio-over-HDMI.

Any solving advice highly appreciated!

THX

I'm fighting with a projector at my school to get XBMC Live working at the right resolution. Looking at the manual on the mfr's web site, I found that it has a native resolution of 1280x800. I followed the instructions in the first post, and I found this in xlog.txt:
Perfect. Exactly the numbers I need to create a ModeLine, straight from the EDID information itself!

So I added this information to a fresh xorg.conf.
After rebooting the machine, Xorg.0.log indicates that it is using the "1280x800_60" mode that I gave it, and XBMC does start up at that resolution. However, XBMC is insisting on running at 50 fps instead of 60.

What's going on?

EDIT: The computer in question has an NVIDIA GeForce 8600 GTS (G84) and I'm running XBMC from a USB flash drive, if that makes any difference.

I found this thread because I was trying to work out how to have X and xbmc start even when the connected TV set is switched off. The instructions here worked for me to set the correct resolution under Ubuntu 12.04, but X would still fail to start because the nvidia driver didn't detect a display. The extra configuration option needed was to add

Option "ConnectedMonitor" "DFP"

in the "Device" section. With that added the X server will start with the TV turned off.

I get this error
