Examinar o readme de fato ajuda às vezes:)
Esse comportamento é intencional para dar a diferentes usuários a chance de ter suas próprias configurações.
Em suma, o arquivo de configuração nvidia-settings é armazenado em ~/.nvidia-settings-rc
e pode ser executado chamando nvidia-settings --load-config-only
na inicialização.

4) Loading Settings Automatically
The NVIDIA X driver does not preserve values set with nvidia-settings between runs of the X server (or even between logging in and logging out of X, with xdm, gdm, or kdm). This is intentional, because different users may have different preferences, thus these settings are stored on a per user basis in a configuration file stored in the user‘s home directory.
The configuration file is named "~/.nvidia-settings-rc". You can specify a different configuration file name with the "--config" commandline option.
After you have run nvidia-settings once and have generated a configuration file, you can then run:
nvidia-settings --load-config-only
at any time in the future to upload these settings to the X server again. For example, you might place the above command in your ~/.xinitrc file so that your settings are applied automatically when you log in to X.
Your .xinitrc file, which controls what X applications should be started when you log into X (or startx), might look something like this:
nvidia-settings --load-config-only & xterm & evilwm
or:
nvidia-settings --load-config-only & gnome-session
If you do not already have an ~/.xinitrc file, then chances are that xinit is using a system-wide xinitrc file. This system wide file is typically here:
/etc/X11/xinit/xinitrc
To use it, but also have nvidia-settings upload your settings, you could create an ~/.xinitrc with the contents:
nvidia-settings --load-config-only & . /etc/X11/xinit/xinitrc
System administrators may choose to place the nvidia-settings load command directly in the system xinitrc script.
Please see the xinit(1) manpage for further details of configuring your ~/.xinitrc file.
