I disabled this shortcut it via System->Preferences->Keyboard Shortcuts, but it still persists. Furthermore, it takes precedence over Alt-F8 in other apps.

How do I really disable this shortcut? Do I need a reboot after disabling it in Preferences?

What desktop environment are you using? (The answer should be something like “KDE 5.3.1”, preferably with some additional indications like “under the default configuration of FooBSD, with BarDesktopManager also installed”.) – Gilles Apr 17 '11 at 12:13
@Gilles - Gnome 2.30.2 under Ubuntu 10.04 – ripper234 Apr 17 '11 at 12:29
Did the answer help? – penguin359 Apr 20 '11 at 20:17
@penguin359 - wasn't able to run ccsm yet. – ripper234 Apr 21 '11 at 10:29

AltF8 is handled by your window manager. In GNOME 2 (with effects enabled) the WM is Compiz. You can use the ccsm tool to edit its keyboard shortcuts.

How do I run ccsm? 'ccsm' itself isn't installed on my machine. – ripper234 Apr 21 '11 at 9:58
@ripper234: If it's Ubuntu, install the compizconfig-settings-manager package. – grawity Apr 21 '11 at 12:25
Thanks - but when I opened ccsm, I saw that alt-f8 was really disabled there (remember, I did disable it via the built in configuration). After a system restart, this seems to be resolved. – ripper234 Apr 21 '11 at 13:12

It looks like a restart did it.

Run gconf-editor

Navigate to


and change it's value to either "" or to anything you like.

[ For safer side, you should reboot the machine ]
