I set up a sage server by adding the following line to my ~/.profile:
nohup sage -c "notebook(interface='', secure=True, automatic_login=False, directory='./sage_notebook.sagenb')" >/dev/null 2>&1 &
I run my sage server from an Ubuntu desktop.
When I login and try to plot graphics from my laptop, the figures appear on my desktop screen.
I tried looking for solutions to this online, but I could not find anything.
