Debian Multimedia :: Nvidia-settings Doesn't Save Across Reboots - Jessie 64bit

I had some issues with nvidia drivers, and removed all of the packages using

Code: Select allrm /etc/X11/xorg.conf and Code: Select allapt-get purge nvidia*

Upon reboot, I was back with nouveau drivers and proceeded to reinstall nvidia drivers according to [URL] .....

Code: Select allapt-get install nvidia-driver
apt-get install nvidia-xconfig
I can then change my refresh rate using
Code: Select allnvidia-settings
but when I hit "Save to X configuration file", I get the following output in terminal:
Code: Select allroot@debian:/home/anon# nvidia-settings
Package xorg-server was not found in the pkg-config search path.
Perhaps you should add the directory containing `xorg-server.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xorg-server' found

As a result, my nvidia preferences aren't saved across reboot.

Here are all of my sources:
Code: Select alldeb [arch=amd64,i386] http://repo.steampowered.com/steam/ precise steam
deb-src [arch=amd64,i386] http://repo.steampowered.com/steam/ precise steam

deb http://ftp.ca.debian.org/debian/ jessie non-free contrib main
