#48 vglserver_config does not work with lightdm

[DRC]

Ubuntu 11 and later use lightdm rather than gdm, and vglserver_config doesn't yet grok how to invoke vglgenkey when lightdm starts up.

Workaround is to switch to gdm:

/etc/init.d/lightdm stop
apt-get install gdm
(this automatically runs 'dpkg-reconfigure gdm', but you can manually re-run it if the gdm package is already installed.)
/etc/init.d/gdm start

Now vglserver_config should work properly.
