Re: [Trisquel-users] Desktop problem - no programs

In order to get xrandr working on a live CD you only need to install the  
package arandr. Then run it and assuming the internal display is called LVDS1  
turn it off using this command:

$ xrandr --output LVDS1 --off
From there you can disable the laptop's monitor permanently using the desktop  
environment's graphical settings.
