There are two major issues.
When modifying the system, either adding or removing software packages, you must "be root", or act as root (a
Super
User) to
DO 'root' activities. This requires either logging in as root, or prefacing your commands with
sudo,
sudo apt-get install geogebra, for example.
But, the other issue is the command must be a valid command. The software package you are trying to install must exist, and it must be 'installable'.
This is the larger problem in trying to get your Mimo 720 USB monitor to work.
The URL you reference mention a package that is no longer available in the current repositories.
The closest one is
http://fr.archive.ubuntu.com/ubuntu/pool/universe/x/xserver-xorg-video-displaylink/xserver-xorg-video-displaylink_0.3-0ubuntu10_i386.debYou could download the file.
Code:
cd ~/Downloads
Code:
sudo dpkg -i xserver-xorg-video-displaylink_0.3-0ubuntu10_i386.deb
...but this does not solve your problem.

The package
xorg-video-abi-11 not installed, and is required, but cannot be found in these same repositories.
Additionally, there have been changes in the way the xserver (the GUI of the system) is configured.
There have been changes in the 6+ years these USB monitors have been more common, as we see by the absence of current software packages.
I have heard this is because support has been 'pre-installed' in the Linux kernel. I have not had time to check if this is just a rumour, or if it was built into the kernel used in the latest Navigatrix.
To make matter even more complicated, I read reports the chipset in the Mimo720 USB changed last year, --but they did not change the model number-- and the DisplayLink software is no longer applicable. Sometimes it is hard to know what is real; one person says 'X', the next says it didn't work, a third says something else.
I believe it will work.
The difficulty for me is I do not have a unit to test and the $300AUD to get one doesn't make it likely I will. This slows investigation, otherwise it's just stabbing in the dark.
