One full screen Ubuntu 14.04 app?

Question

linux

There are several machines in the computer club running Ubuntu 14.04.
Sometimes lovers of 10-15 years old launch 20 HL toys, CSS, Serious Sam (if everything is "native", without wine.), And then they get bored with questions about why the game slows down =(
Actually, is it possible to make some kind of check that one would be launched and only one full-screen application?
PS Tell me, is it possible to make an ssh shortcut with a ready-made command on Windows by any means?
For example, ssh 192.168.8.104 >> auto authorization from root >> shutdown -h now.
My knowledge is very modest.
Thanks in advance to all who responded .

Answer 1

For the 2nd part of the question, you can use mputty
You can set up any number of hosts, autologin, script execution.

Answer 2

And what's the problem with making it so that only one copy is launched - through a script? First, end all running (including other games), then start.
