nvidia restricted binary drivers and settings

I have found a really nice tool for setting up the xorg.conf and daul view. From the command line in Ubuntu type gksudo nvidia-settings. Up pops nvidias GUI tool for setting up your nvidia card and xorg.config.

Only it has problems, or at least I had problems. they relate to where some of the advanced nvidia settings are stored in a file called .nvidia-settings-rc. From your home directory type ls -a .nvidia-settings-rc. This file is basically used to initialize your graphics card at boot and is linked into the boot process through the init folder in /etc/rcX.d.

The problem I had with this file was that the permissions on it doesn't allow the program to rw access it and execute it. I may be wrong here. What I did to fix the problem was change the permissions from
user@user-machine:~$ ls -l .nvidia-settings-rc
-rw-r--r-- 1 user user 1511 2007-06-06 18:33 .nvidia-settings-rc
user@user-machine:~$ ls -l .nvidia-settings-rc
-rwxr-xr-x 1 aaron aaron 1511 2007-06-06 18:33 .nvidia-settings-rc
with a chmod 755 .nvidia-settings-rc. now it probably dose not need the execute permissions some thing to experiment with but make sure it has the rw.
basically try:
$ chmod u=rw,g=rw,o=rw .nvidia-settings-rc
$ gksudo nvidia-settings.

I still get a lot of ERROR .... (no Display connection) messages on the command line but at least now it actually generates the xorg.conf file in the /etc/X11/ directory.

I'm not sure what the error messages mean or how to fix it. It has some thing to do with the advanced options of gamma, colour saturation. This can be fixed but I didn't find it necessary to. There is some discussion at the nvidia forums. Check out this thread http://www.nvnews.net/vbulletin/showthread.php?t=61396 it seams to have the most though discussion on fixing it.

Please post you comment on this if you have any solutions for the ERROR ... (no Display connection) problem.
