Command to load nVidia x-server dual monitor settings in Ubuntu Terminal?

edameiro · February 7, 2023, 8:36pm

I connected the AV receiver to the 760 GeForce video card with HDMI, and connected the av with a 2nd HDMI cable to the monitor (not necessary). I then connected a DVI cable from the video card to the monitor, since the HDMI did not support 1920x1200 (only 1920x1080) resolution.

The mirror display settings in Ubuntu System Setting crashes when I select it. But thankfully the x-server allowed me to mirror the av receiver with the monitor as primary. When I go back to Ubuntu display, mirror is already selected, due to adjusting it in x-server.
I have attached a picture of the configuration settings.

To export the settings, I had to execute the following in terminal; sudo nvidia-settings does not work.

sudo chmod u+x /usr/share/screen-resolution-extra/nvidia-polkit

Then click ‘Save to X configuration’ file, located in /etc/X11/xorg.conf.

Ubuntu supposedly looks for the file at, /usr/share/X11/xorg.conf.d/10-nvidia.conf.

I copied and pasted the contents (appended) to 10-nvdia, after the following contents:

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"
EndSection

This is the paste-bin of the file
[New users aren’t allowed to post links], but I can paste the entire contents in a later post.

There’s another configuration that x-server can export when you go to ‘nvidia-settings Configuration’ > Save current configuration; I also selected and deselected ‘Include x display name in files’, and it made no difference in what I’m trying to achieve.

This exports a hidden file named ‘.nvidia-settings-rc’ to the /home directory. This is the paste bin:
[New users aren’t allowed to post links], but I can paste the entire contents in a later post.

The command ‘nvidia-settings -l’ did not load the desired ‘mirror’ settings upon system restart. This supposedly loads ‘.nvidia-settings-rc’.

I used the more explicit commands:
nvidia-settings --config=~/.nvidia-settings-rc --load-config-only
Mirror settings did not load

nvidia-settings --config=/usr/share/X11/xorg.conf.d/10-nvidia.conf --load-config-only
Got error message: ‘Section “ServerLayout”’ (Unrecognized attribute name).

Since Ubuntu is able to remember the settings upon restart, my main goal is to write a bash script that will load at start up, and execute the settings file.

I’ve also verified x-server is a ‘Start up’ program with the command, gnome-session-properties.

You can’t load Xorg config files on the fly after the server has started.
You should be able to use xrandr instead.

Thank you for the response

I encountered a StackExchange post saying to specify script file in the directory:
`‘~/.config/autostart/setup_monitor_display.desktop’

With their desired configuration of:

# Wait until GUI is ready
X-GNOME-Autostart-Delay=1
xrandr --output DP-0 --rotate left

I executed xrandr, and got the following the for HDMI-0, the ‘monitor’ I keep needing to adjust and mirror:

HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 708mm x 398mm panning 1920x1200+0+0
   1920x1080     60.05*+  59.94    50.00    60.00    50.04  
   2880x576      50.00  
   2880x480      59.94  
   1440x576      50.00  
   1440x480      59.94  
   1280x720      59.94    50.00  
   720x576       50.00  
   720x480       59.94

My main question now is what command(s) would I send to xrandr to duplicate these settings, that were set with x-server GUI?

Please post the output of
xrandr --verbose

This is the output of xrandr --verbose

Ok, seems you’re using panning on the lower resolution, please try this:
xrandr --fb 1920x1200 --output DVI-I-1 --pos 0x0 --output HDMI-0 --pos 0x0 --panning 1920x1200
You might also try scaling instead of panning
xrandr --fb 1920x1200 --output DVI-I-1 --pos 0x0 --output HDMI-0 --pos 0x0 --scale 1x1.11

Thank you very much.

The following worked:

 xrandr --fb 1920x1200 --output DVI-I-1 --pos 0x0 --output HDMI-0 --pos 0x0 --panning 1920x1200

While the other, --scale 1x1.11, resulted in the ‘Wallpaper/Desktop background’ appearing before the list of applications when I click the 9 squares at the lower left hand corner of the screen, requiring me to do ‘Alt F2’, then R key, essentially nullifying the xrandr settings.

To persist the settings, I went to cd ~/.config/autostart/, and created a setup_monitor_display.txt, and made it executable with, sudo chmod +x setup_monitor_display.txt.

Then execute gnome-session-properties in terminal, click Add button on the GUI, Name it, then for command: sh -c '~/.config/autostart/setup_monitor_display.txt'. I also disabled/unchecked the ‘NVIDIA X-server Settings App’ which may not be necessary.
