[ale] Configuring X in Ubuntu

[Christopher Fowler]

Can someone tell me what program to run to reconfigure X windows in
Ubuntu Live?

I'm using the persistence to keep my home directory persistent across
boots but I do not care about hardware config persistence since I plan
on booting on different pieces of hardware.  The snapshot feature of
Ubuntu live wants to keep the home directory and the config persistent
so to get X to work again after a boot on a different machine I need to
reconfigure it.
