Hey damNmad,

I am running a 19 GPU rig and can't rely on the auto-creation of xorg.conf because it will detect all 19 cards and will list all 19 in sections Server Layout, Screens, and Devices. If the Server Layout section has more than 16 screens listed in it, X will fail to start (see xorg.0.log) and without X starting, nvidia-settings cannot run and no overclocking will occur for any of the 19 cards.

The trick is to make it so that only 16 screens appear in Server Layout, but allow all 19 to be listed in both Screens and Devices. The result of this is that 16 GPUs will be OC'd and 3 won't. But that's better than none getting OC'd.

I *was* running 1.3 when it tanked. I worked on it until things just didn't seem right so I reflashed 1.3 back on my USB stick and I got it running again, but it was unstable and would either slow way down OR the miner process would totally quit. So I decided to move to the community version 1.4v2. This also has not solved my issue so far.

My only solution thusfar has been to force my version of xorg.conf on every boot, and for whatever reason, something changed and I'm getting some sort of default configuration written into xorg.conf that only has a few cards and they aren't detected as nvidia. So the miner never starts cuz there are no GPUs detected, I guess.

So where I am now is that I have to:

1. Edit /etc/init.d/gpu and commenting out the sections that mv xorg.conf to xorg.conf.backup and create a new one based on nvidia-smi queries.
2. Place my custom xorg.conf in /etc/X11
3. Take that same xorg.conf file, rename it to 52-nvidia.conf, and put it in /usr/share/X11/xorg.conf.d/

Any thoughts?
