I recently installed Ubuntu 13.04.
I changed my shortcut for "Lock screen" to the sleep button on my keyboard.
But instead of just locking the screen it puts my computer into hibernation/suspend mode, which is kind of annoying. I can't find where the hibernation mode is bound to the sleep button.
I already tried
gsettings set org.gnome.settings-daemon.plugins.power button-sleep 'nothing' (as mentioned here) but it doesn't affect the sleep button and it still goes into hibernation/suspend.
Can you help me?
