I want to define a new keyboard shortcut in the graphic “settings/keyboard/shortcuts” to start-up the gitlab Name: Gitlab Panel
Commands: su -c "/opt/gitlab-7.9.3-0/"

The attribute of this file is in the following :

/opt/gitlab-7.9.3-0/ ELF 64-bit LSB executable, 
x86-64, version 1 (GNU/Linux), statically linked, stripped

But when I press the shortcut, there is no response to me.


Try using /usr/bin/gksu (from the package of the same name) instead of su. (See the man page for the appropriate syntax.) Then you will be prompted for the sudoer password.

I install with apt-get install gksu, and change the command to ‘gksu “/opt/gitlab-7.9.3-0/”’. Then the problem is solved.
