[Libdlo] running 2 instances of X for multihead display

[Marcus Becker]

Hi,

it looks to me you didn't install the display module for Xorg (does
Ubuntu still use Xorg or did they switch to wayland?)
run aptitude and search for those modules like:
aptitude search displaylink
and
aptitude search void
then you can install them via
aptitude install <packagename> (usually something like xf86-video-displaylink)

xfce4 has a startscript, right? like '/usr/bin/startxfce4' (don't know
much about Debian or Ubuntu :/ )

Hope that helps :)

Marcus
