@Karl Try this:
gsettings set org.gnome.desktop.wm.keybindings toggle-shaded "['']" This shall remove the shortcut. Or you can reassign it like this: gsettings set org.gnome.desktop.wm.keybindings toggle-shaded "['<Primary><Super>s']" Then restart gnome shell. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/965921 Title: gnome-shell most keyboard shortcuts not working Status in “gnome-control-center” package in Ubuntu: Confirmed Bug description: Updated Bug Description ======================= For Ubuntu 12.04, System Settings (gnome-control-center and gnome- settings-daemon) was patched to continue to support the gconf keyboard shortcuts used by Unity, Unity 2D, and the GNOME Classic sessions. Unfortunately, GNOME Shell now uses gsettings keyboard shortcuts so GNOME Shell ignores keyboard shortcut changes that get entered into System Settings>Keyboard>Shortcuts. This should be fixed for Ubuntu 12.10 but it's too late and complicated to fix for Ubuntu 12.04. One Workaround ============== Install dconf-tools Run dconf-editor Look in org.gnome.desktop.wm.keybindings or org.gnome.mutter.keybindings Another Workaround ================== Set a custom keyboard shortcut. This is useful if you want to set Ctrl+Alt+F to open Firefox for instance. In System Settings, click Keyboard. Switch to the Shortcuts tab and click Custom Shortcuts at the bottom of the list. Click the + button and add a name to remember the shortcut and the specific command you want to execute. Click Apply. Find the name in the list and click the right half of the row. "Disabled" should change to "New accelerator". Enter the keyboard shortcut you want to use. Ctrl+Alt+T to open the terminal and several other usual shortcuts from Unity have been added to GNOME Shell on April 17.
