For a Linux system with (Py)GTK installed, here's a simple way to set up
a system tray icon which indicates, roughly, whether the notebook server
is running:
1. Save the attached script as $SAGE_ROOT/local/bin/sage-tray-icon .
2. Make it executable.
3. Insert "sage-tray-icon &" between the sage-cleaner and sage-notebook
commands in the sage-sage script.
There's probably a much better way. Does Sage have an equivalent of
rc.local?
I'm not sure how to get information between the notebook and the icon,
e.g., to have the latter blink when a long computation is finished. If
anyone wants try, these might help:
