plot in sage console, through an ssh connection, with the LiveCd
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.
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:
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.
EDIT: I've installed xeyes on the live cd, and it doesn't open. Running a netstat or a top, I can't see any sign of the X server running. I think the live CD DOES NOT HAVE AN INSTALLED X SERVER. This settles the question, at least partially. Instead of trying to install the X server on the sage live cd, I'll start with a virtual machine with X preinstalled, and then install Sage. I'll report back here when done.
