I have a DisplayLink monitor that I am trying to add to my Ubuntu desktop. After plugging it in, the screen turns completely green, which I understand means that the DisplayLink kernel module is installed and can interface with the device.

Adding the monitor to my xorg.conf shouldn't be too hard except there is no /etc/X11/xorg.conf. Apparently I have to generate one - so that's what I tried to do with the following command:

Xorg -configure

However, this seems to be failing. Here is the output of the command:

1 Answer 1

The vmware graphics driver (vmwgfx) is an external add on driver by VMWare, not one supported by core X.org. Xorg -configure really is only valid for the core official drivers.
