How to awake emacs gui after pressing ctrl+z

Question

I'm using emacs gui in Gnome. After pressing ctrl+z, emacs window is minimized. However, if I bring the window to front, it doesn't respond any key press and mouse event. I searched the web only found bringing back it within the commandline. But how to reactive emace when using it in a GUI mode ??

Answer 1

If you press C-z by mistake then you can add this to your .emacs to make C-z do nothing:

(global-unset-key (kbd "C-z"))

I did that after pressing C-z many times by accident.

Answer 2

You may have to send the process a SIGCONT signal. You normally do this in the console by running kill -CONT $emacs_pid or killall -CONT emacs. If you insist on a GUI solution, you can try the task manager shipped with your distro.
