[SOLVED]nvidia-settings can't parse generated config file?

Using nvidia-settings --load-config-only, I get this error:
Error parsing configuration file '.nvidia-settings-rc' on line 4: 'Section "ServerLayout"' (Unrecognized attribute name).

Th file looks like this:

That's an xorg config and no nvidia rc - i'd say you ran nvidias xorg config tool (since you obviously don't know what you're doing and it easily causes trouble: don't) and stored it overriding nvidias settings.

Use the "Save current configuration" button on the "nvidia-settings Configuration" page in nvidia-settings …

Ok, that makes sense. I save the config on the X configuration page as /etc/xorg.conf and that worked. Thanks!

What's wrong with it? Why shouldn't I use it?

In the case of of a hybrid graphics system ( using either bumblebee or optimus ) the xorg.conf generated will not work.
In the case of an nvidia only system you have a monolithic xorg containing options that X will ignore or will be provided by autodetection and the useful configuration options could be provided by a smaller conf snippet.
For instance if you remove your systems /etc/Xorg.conf do you notice any difference?
Or to analyze the Xorg.conf from post #1

Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
Option "Xinerama" "0"
EndSection

Unneeded autodection will provide the same result

Section "Files"
EndSection

Empty section serves no purpoice.

Section "InputDevice"
#generated from default
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/pasux"
Option "Emulate3Buttons" "no"
Option "ZAxisMapping" "4" "5"
EndSection

Section "InputDevice"
#generated from default
Identifier "Keyboard0"
Driver "kbd"
EndSection

X will skip you should see a message to that effect in the system's xorg.log

Section "Monitor"
# HorizSync source: edid, VertRefresh source: edid
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Samsung s22f350"
HorizSync 30.0 - 81.0
VertRefresh 50.0 - 75.0
Option "DPMS"
Endsection

Section needed if autodetection fails ( if you switch monitors having X set to a different set of values than the monitor supports will cause issues)

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce GTX 1060 3GB"
EndSection

Unneeded in a system with only a single GPU

Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaulttDepth 24
Option "Stereo" "0"
Option "nvidiaXineramaInfoOrder" "DFP-1"
Option "metamodes" "720x480 +0+0"
Option "SLI" "Off"
Option "MultiGPU" "Off"
Option "BaseMosaic" "Off"
SubSection "Display"
Depth 24
EndSubSection
EndSection
Section "Screen"

Some of section needed if autodetection fails.

On top of what loqs said, the better approach is to configure things you want to adjust as configlets in /etc/X11/xorg.conf.d/20-nvidia.conf, eg. to pass

Section "Device"
        Identifier "Default nvidia Device"
        Driver     "nvidia"
        Option   "NoLogo"              "True" # no spam
        Option  "CoolBits"              "24"     # possibly more options in nvidia-settings
        Option  "TripleBuffer"       "True" # enforce triple buffered GL, glswap won't block
EndSection

The monlithic /etc/X11/xorg.conf is actually considered deprecated since quite some time.
You can do likewise for the monitor and screen section, in "Monitor" use the label provided by xrandr as Idetifier to match the proper output (eg. "DVI-I-1" or "HDMI0")

Ah, I see. Thanks for analyzing the script as well, loqs. I learned quite a bit.

Cool, please always remember to mark a thread as [SOLVED] (edit your first post) once you're fine with the results (to hint others to either skip it or that there might be useful insights to their similar problem)
