X11 Forwarding

As SCTs, we have to use an Epson Projector to display our slides in Supinfo, unfortunately, it’s only Wind*ws compliant.

This night, I’ve just found a way to keep my laptop under Linux and use the Tablet PC in order to display my linux programs on the wall.

I connect the Tablet PC ( Windows XP ) to the Epson projector and use a ssh connection between my laptop and the Tablet PC to forward the X Window display.

First install OpenSSH

alex@pentagram#sudo apt-get install openssh-server

then be sure that you have this two line in the /etc/ssh/sshd_config file

X11Forwarding yes
X11DisplayOffset 10

that’s all we have to do on the laptop.

On the Tablet PC, we have to install Xming, it can be downloaded here on sourceforge

http://sourceforge.net/project/showfiles.php?group_id=156984

Download the Xming installer , or Xming-fonts installer.

Install it and download after putty at http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Click it to open the software.

Scroll the left menu until the SSH part, click on X11 and check the box X11 Forwarding

Back to the Section part, enter the IP address of your laptop, and OK, you maybe will have to accept the RSA Key.

Connect with your login and pass and test it by launch a graphic application like gnome-calculator ( ubuntu-like ) or gnome-terminal to have another terminal

Don’t forget the & , putty is the only link to keep the connection alive
