Tue 2012-03-06 I just noticed an option to log in as 'guest' on our Ubuntu laptop. I cannot remember asking for it, and I certainly don't want it, so I looked for a way to disable it. In Ubuntu 10.04 LTS the guest option is provided by the package gdm-guest-session. I went into the Synaptic package manager and uninstalled it. After logging out and in again, the guest option is no more.

From a year and half ago: grey fly with yellow wing bases, probably Fannia lustrator (Diptera: Fanniidae). A male because the eyes almost touch on top of the head.
