Details:

Under Gnome, if I launch Octave using the ".desktop" launcher, as is done when
you launch from your Applications menu or from your dash, a new window is
created with a generic icon. This represents the running instance of Octave.
The correct behavior is for the Octave icon to become associated with the
running instance of the program so that, for instance, clicking the launcher
again will bring the currently running instance to focus instead of creating a
new instance.

This is because the ".desktop" file included with Octave (as it exists in the
Debian Repo anyways) does not give any hints to the window manager as to which
windows should be associated with the program. The easiest fix is for the
".desktop" file to include the line:
StartupWMClass=octave-gui

This will give the window manager what it needs to do proper window
association. I don't know if this is an issue with Octave exactly, or with the
Debian package, but if it is in Octave this small change could improve the
user experience for lots of Linux users. Thanks.

Bryan
