[Nix-dev] Re: Configuring dual head

[Ludovic Courtès]

Hello,

These days, multiple screen are handled via the RandR extension, e.g.,
via xrandr(1), grandr(1), or similar.

For instance, on my laptop, the screen plugged in the DVI output is
switched on with "xrandr --output TMDS-1 --auto"; it can be made to
appear above the laptop's LCD screen with "xrandr --output TMDS-1
--above LVDS".  Typing just "xrandr" lists the available screens.

Thanks,
Ludo'.
