In a script I want to open a window which is missing the "close" button in the title bar, so that it can't be accidentally be closed, but still has the "minimize" and "maximize" buttons.

Is this possible? Maybe via some window manager arguments?

I'm using Ubuntu 13.04 with Unity.

  • At first this is supposed to work with gnome-terminal and xfce4-terminal. I want to run a command line tool which takes a very long time to finish (MrBayes phylogeny) and want to prevent someone accidentally closing the window. Maybe this is also applicable for other windows when needed. – joschi Jul 26 '13 at 14:58
  • I don't think it is possible from a script, but maybe others will have an idea. – meskobalazs Jul 26 '13 at 15:01
  • There must be a way as the update-manager also only got a minimize button. – joschi Jul 26 '13 at 15:04
  • From an application you can do this, GTK+ has options for this. – meskobalazs Jul 26 '13 at 15:05

As a little workaround I found the Window Rules option in CompizConfig-Settings-Manager where I put xfce4-terminal (that I generally don't use and installed just for that purpose) to "Non Closable Windows".

Now I can start shell scripts using xfce4-terminal to execute commands

xfce4-terminal -e "command you want to run"

that mustn't be terminated by accidentally clicking the close button by unexperienced users.
