I am using Ubuntu 14.04 x64 w/ Unity. I like how the Task Manager shows up in Windows with Shift+Ctrl+Escape. So I tried creating a similar keyboard shortcut in Ubuntu with the command gnome-terminal -e htop.

Nothing happens when invoking that shortcut. However, if I assign a different combination, say Ctrl+Alt+H, it works fine.

What am I doing wrong? Is Shift+Ctrl+Escape reserved or something? It used to work perfectly in 13.10 and before.

  • (1) Trying in a terminal, make sure the command works. (2) Why don't you use gnome-system-monitor instead?

  • @AliNa: Regarding (1), The command (obviously) works in the terminal, and it works if the shortcut combination is different, as mentioned. As for (2), I like htop.

  • I've just run into precisely the same error. I'll add that you can use dconf-editor to view the actual shortcut configuration live at /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings. Not found a workaround, yet, though. A temporary workaround for me is bind Ctrl-Shift-ScrollLk

  • Ah, it works with regular GNOME, just Unity appears to break it.

Use CCSM to assign the command and keybinding and it will work in Unity.

To get Compiz Config Setting Manager do the following:

  • Open the Terminal by pressing Ctrl+Alt+T and type:

    sudo apt-get install compizconfig-settings-manager compiz-plugins-extra -y
  • Open CCSM
  • Select the commands option
  • Assign the command on line 0

Select the Keybinding tab and assign the hotkeys you like to trigger the command.

    I don't think this answer can work for short cuts with the esc key. See this answer
