Turn on 2nd NVidia screen using command-line

  • 772

I have a Ubuntu machine next to my TV. Sometimes I use my TV (hdmi) as a secondary monitor, twinview.

Using the "NVidia X Server Setting", nvidia-settings, I can turn the second monitor (TV) on or off. (NVidia driver version is 260.19.06)

However, since I do this quite frequently I would like to install a keyboard shortcut. So step one is to turn on/off the 2nd monitor using command line.

Any idea on how to control this, using command line?

Cheers Leif

    disper has worked very well for me for controlling an nVidia card for the same purpose. My second display was a TV, btw. You can install disper from this ppa: https://launchpad.net/~disper-dev/+archive/ppa

  2. try nvidia-settings -h

    I'm not sure about this, but nvidia-settings seams to be a graphical front-end to edit ~/.nvidia-settings-rc

    So if you save this file, use nvidia-settings, to add the TV display and save your settings, you should have two configuration files for your two setups.

    Now use nvidia-settings -l conffile to change the configuration.

    A bashscript could look like:

    #!/bin/bash
mv conf1 tmp.conf1
mv conf2 conf1
mv tmp.conf1 conf2
nvidia-settings -l conf1

    So this would toggle between the two settings
