Need Help Configuring Fan Controls for NVidia GTX 480
I have the latest nvidia-experimental-310 drivers.
It seems that regardless of GPU load, the NVidia driver doesn't do anything to change fan speed on my graphics card. So, I found an article explaining how to add a fan slider into the NVidia control panel. I need to edit the xorg.conf file, but I don't have one. I found an article explaining how to generate an xorg.conf file. When I try to do so, I get the following error: Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.
I also found a program someone made for fan profiles, like what I have with MSI Afterburner in Windows, but I also have to edit the xorg.conf file to use it. Can someone please help me?

To create an xorg.conf file, run the NVIDIA Settings control panel as root user and then select "X Server Display Configuration". Then press the "Save to X Configuration File" button.

You can then add the "Coolbits" entry to the xorg.conf and log out and log back in.

However, if you feel that your fan speed isn't adjusting properly, a post on the NVIDIA Linux forums may be appropriate. There could be a bug in the driver.

Thank you so much, I am now able to control fan speed manually.
I do have another question though. I have my main monitor connected to the GTX 480, and that works just fine, but my second monitor on the integrated graphics in my i7-2600K does not display anything and is not detected by Ubuntu. any ideas?

I do not believe that you can simultaneously run the NVIDIA X driver and the Intel X driver (with the caveat that it might be possible to do so if running two separate X servers, but I'm not familiar with that and Ubuntu doesn't have a default configuration for that).

Are you looking to use both GPUs for separate purposes, or simply want a dual-monitor setup?

simple how-to create /etc/X11/xorg.conf file
with option for NVIDIA GPU fan control settings

1. start a terminal (gnome-terminal, etc.)
2. type "sudo nvidia-xconfig --cool-bits=4" (without the "")

(Tested on Ubuntu 12.10 64Bit with nvidia-experimental-310 driver on a NVIDIA GeForce GTX 660.)
