Auto export display when coming from SSH

[ -n "$SSH_CLIENT" ] && export DISPLAY=$(echo $SSH_CLIENT | awk '{ print $1 }'):0.0
In some case, you need to use remote gui on servers or simple machines and it's boring to see "cannot open display on ..." if you forgot to export your display. Juste add this line in .bashrc on remote machine. Dont forget to allow remote client on your local X server : xhost +

Why on earth? "xhost +" is dangerous, why don't you use "ssh -X remote_host"? Why .bashrc? There are lots of shells, not everyone is using bash, try to make your solutions portable!

"ssh -X remote_host" dont work every time, ie if sshd_config disable X11Forwarding. About .bashrc, it should work in .profile

If someone disables X11 forwarding it is on purpose, no need to send data over insecure channels just because you can.
