What defaults X uses when there is no xorg.conf file

[kingofearth]

I need to get Direct rendering working on my computer, Im using the Gentoo docs so thats not what I need help with, but part of it requires that I edit xorg.conf. The problem is that I dont have an /etc/X11/xorg.conf file. I've tryed making one but then X doesn't work. So is there anyway to find out what X is using so I can make xorg.conf and get direct rendering working?

Did you run that 'xorgconfig' command as your user? That should create a brand new xorg.conf based on your answers to the questions. Might be a good place to start at least.

yea, but I dont know what to put in for my monitor. Its a laptop screen, and the screen rotation/resize things says the refresh rate it 0Hz so I dont know what moniter to select. X works without the file, so Im wondering if their someplace I can look to find out what monitor settings its using to make my own xorg.conf so I can enable direct rendering.

Google for your laptop vendor and model, there should be someone who has tried to get it working with linux and (hopefully) X, and posted the specifications.

If you can boot KNOPPIX 3.7 liveCD with good resolution, it will give you xorg.conf file tailored for your computer. It worked for me very well:
1. Boot KNOPPIX
2. Open terminal
3. #su
4. mount /dev/hda1 /mnt/hda1 (hda1 is your hard drive root partition, could be different)
5. cp /etc/X11/(dont rememeber where exactly)XF86Config-4 /mnt/hda1/xorg.conf
5. edit xorg.conf either in KNOPPIX or after reboot deleting a lot of unneeded stuff.

You should configure xorg with the native resolution of your LCD panel. You don't need to worry about refresh rates since it is a fixed frequency display.

My laptop has a 1600x1200 resolution and this is the appropriate part of my xorg.conf
