-=== Mac ===+==== How to run several X-Servers simultaneously ====
  
-=== Windows === +Have you ever wondered why Linux has 6 different virtual text-terminals but only one graphic-terminal? In fact, Linux has also 6 graphic terminals, it just uses only one by default. 
-== Why can't I run Windows OS on my my workstation ? ==+ 
 +When you start your X-Server with the command "startx", the system assumes, you want to send the graphical output to the first graphic-terminal, which you can access by pressing Ctrl-Alt-F7. 
 + 
 +  "startx -- :0" 
 + 
 +is normally the same as just "startx", it puts the graphics to the first graphic-terminal 
 + 
 +  "startx -- :1" 
 + 
 +starts another X-Server with its output to the second graphic-terminal 
 + 
 +  "startx -- :2" 
 + 
 +starts another X-Server with its output to the third graphic-terminal 
 + 
 +... so we can run upto 6 different X-Servers simultaneously! 
 + 
 +You probably already knew, that you can switch between the text-terminals with the combination Alt- and the F1 to F6 keys. 
 +Parallel you can switch between the graphic-terminals with Ctrl-Alt- and F7 to F12. 
 + 
 + 
 +==== How to connect to a remote X-Server, i.e. control it ==== 
 + 
 +Have you noticed that, when you open an X-Server on your box, the system will open the port 7000 (thats the standard)? So it seems possible to connect to this port and trasmit the graphic data over a network(i.e. the internet). For this to be possible you have to do the following configuration steps: 
 + 
 +  - On the server: 
 + 
 +     - Allowing the server to send data to your client : 
 +       "xhost +[ip]" whereas [ip] is the IP of the client 
 + 
 +  - On the client: 
 + 
 +     - Setting the server output to the remote X-Client: 
 +     "export DISPLAY="[ip]:0" whereas [ip] is the IP of the client 
 + 
 +After doing this all programs that use X which are executed on the server will be visible and controllable on the client. The CPU time used by the program, however, will be the server one's. 
 + 
 +Thats pretty much it. I hope that wasn't too cryptic. Have fun.
