Can't save nvidia settings for screens after reboot

rated 0 times [ 8] [ 0] / answers: 1 / hits: 26097 / 2 Years ago, thu, december 2, 2021, 4:54:48

I have two screens and sometimes I just want the 27" to display. So far I have tried to run the nvidia-settings as

sudo -s

nvidia-settings

But every time I reboot I have to redo my preferences..
My laptop is asus g75vw
nvidia driver version is: 331.38
Ubuntu 14.04

I have tried with new drivers, nothing changed exept now the standard settings make the screen duplicate...

Is there any alternative simple way I can set settings to persists after reboot?

the nvidia settings

The simplest way is to run nvidia-settings as root:

sudo nvidia-settings

You will now be able to use the "Save to X Configuration File" button.

Alternatively, you can simply save the file generated as /etc/X11/xorg.conf but don't use the file in your question. That one is incomplete, presumably because you did not copy the entire thing.

It seems as though something is overwriting your xorg.conf file. As an (inelegant) workaround, you can use xrandr (without sudo) to activate/deactivate your screen:

To deactivate the second screen and use only your primary monitor:
```
xrandr --output LVDS-0 --off 
```

To activate it:
```
xrandr --output HDMI-0 --auto --primary --output LVDS-0 --mode 1920x1080 --right-of HDMI-0
```
IMPORTANT: I'm not sure from your xrandr output if your screen's identifier is MI-0 or HD MI-0. I've never seen an identifier that includes a space which is why I used the former, but you might need to use xrandr --output "HD LVDS-0" --auto --right-of MI-0 instead.

If these commands successfully switch between your desired layouts (if not, let me know and we can tweak them), you can turn them into a simple script:

#!/usr/bin/env bash



if [[ $1 = "off" ]]; then

    xrandr --output LVDS-0 --off 

else

    xrandr --output HDMI-0 --auto --primary --output LVDS-0 --mode 1920x1080 --right-of HDMI-0

fi

Save that as switch_screens.sh and make it executable (chmod +x switch_screens.sh). You can now go into settings from the GUI, go to "Keyboard" => "Shortcuts" and create a custom shortcut for each command:

enter image description here

and for turning it off, set the "Command" to ~/switch_screens.sh off:

enter image description here

Choose whatever shortcut key combination you want and you can then activate/deactivate the screens at will.

You can also activate it directly from the terminal with:

~/switch_screens.sh

And deactivate it with

~/switch_screens.sh off
