I honestly don't know if it can save those settings. For me, I wouldn't want to save such a setting, since I sometimes use my PanP5 on battery power, and the time it will last on a full charge is already just under 2 hours... I don't want to make it worse by defaulting the graphics card to its most power-hungry state.

Having said that (hopefully to dissuade you from wanting to do something like that ) you can try the following:

1) Open a terminal and type

sudo nvidia-xconfig

This will produce an xorg.conf file that NVidia X Server Settings understands.

2) Restart X (Log out, log back in... no need to reboot).

3) Now, you need to edit your new xorg.conf:

gksudo gedit /etc/X11/xorg.conf

Find the "Device" section -- it will look something like this:

Section "Device"
	Identifier     "Device0"
	VendorName     "NVIDIA Corporation"
	BoardName      "GeForce G 105M"
	Driver	"nvidia"
	Option	"NoLogo"	"True"
EndSection

Add the following to this section (the line in red is what you add):

Section "Device"
	Identifier     "Device0"
	VendorName     "NVIDIA Corporation"
	BoardName      "GeForce G 105M"
	Driver	"nvidia"
	Option	"NoLogo"	"True"
        Option  "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x3322; PowerMizerDefaultAC=0x1"

EndSection

Using the line in red, we have told your G105M card to use regular adaptive scaling of the GPU whilst on battery power and Maximum Performance when plugged in. To make it use Maximum Power all the time whether plugged in or not (NOT RECOMMENDED), use

Option  "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefault=0x1; PowerMizerDefaultAC=0x1"
