Hi
I have installed Synaptic into my chrooted environment but get an error "synaptic:could not open display"

I have read the instructions that say you have to export DISPLAY........
#DISPLAY=myip:0.0 (replace my ip with your actual IP)
#export DISPLAY
#synaptic

I have tried this with every combination I can think of but nothing is working. This is the output:-


Setting up synaptic (0.16-6) ...

root@not a tty[/]# export DISPLAY
root@not a tty[/]# synaptic

I am obviously doing something wrong
Thanks for any help
