I'm a Windows user, and I use sage with the Live Cd, version 4.8.
I use putty.exe to connect to the virtual machine, login as sage, and run the sage console.
I would like to plot from the sage console, through this ssh connection.
I've followed this guide to enable X11forwarding on the VM, and this guide to setup X11forwarding on the Windows machine.
When I run a simple script from within the sage environment like
var('x')
f(x)=x**2
plot(f,(x,0,2))
the plot command returns without any error, but no window is created. I've also tried to run from the bash console, before entering the sage environment, this command:
export DISPLAY=0.0
without any improvement. I actually don't even know if X11 forwarding is working, because I can't find any X program on the livecd like xclock, xeyes, etc. to test them.
Do you have any idea how to tackle this problem?
