[xmonad] Problem running Xmonad

Hello, I am trying to get xmonad running on my laptop (ubuntu hardy) and run into some small but annoying problems which I cannot solve browsing through the docs: - I do not have extra workspaces: mod + 1 ..9 does not work - I do not have power management: just need suspend when lid is shutdown. I tried launching gnome-power-manager with gnome-settings-daemon but this does not work, reporting failure to connect to dbus - fonts aren't antialiased on firefox (very minor, I know, but unpleasing to the eyes) I would greatly appreciate any help. Thanks Arnaud
