I noticed in Ubuntu 11.10, that finally there is possible to log in with guest account already from log in screen. The last step is remaining - how to enable the guest account automatically log in, e.g. when computer starts? This would be very helpful for public computers, e.g. in libraries, schools, universities, student campus etc. This would be workaround for user account deep freeze feature, which is still missing from Ubuntu.
