I have a Mimo monitor and it runs USB. I tried and failed and I don't know what to do......All i get from the USB screen is just a green screen. Anyone could help me?
You will need to install the xserver-xorg-video-displaylink package to get support for this class of devices (identifiable by connecting via USB and presenting a green screen on successful initialisation). The X server does not currently support hotplug events on the USB bus, so you will need to create an xorg.conf file to use such a device. An example xorg.conf file is included in the package (under /usr/share/doc/xserver-xorg-video-displaylink/examples).
If the above is not working for you, please file a bug against xserver-xorg-video-displaylink: there may be some variation between displaylink devices, which may not be handled completely by the existing driver (but any such lack of support is a bug to be fixed, rather than a result of user error).
