Re: [gentoo-user] Video Out on laptop

[Robert David]

So to enable external output you can do this:

xrandr --output VGA-0 --auto --output LVDS --off

to switch back

xrandr --output VGA-0 --off --output LVDS --auto

you can assign this to some shortcuts. Or do a acpi script for the
hotkey. I have done similar for docking and undocking on my thinkpad.

Also you can use the tools for your DE, for example krandrtray for KDE
or gnome it has in Settings I think.

Robert.
