您好，
我需要在 ubuntu 12.10 中设置一个热键，我使用：
gsettings(dconf)
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom2/ binding '<Primary><Alt>s'<br>
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom2/ binding '<Primary><Alt>s'<br>
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom2/ command 'gnome-terminal'
但是当我用 gsettings 查看这个架构时，我只看到：
gsettings get org.gnome.settings-daemon.plugins.media-keys custom-keybindings
@as []
但是当我使用 dconf 查看这个模式时：
dconf list /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom2/
binding
command
我究竟做错了什么？
