Ubuntu 7.10 install freezes

[Danny Colligan]

Can't help you with 1 without more information, and probably neither
can anyone else on this list without more than an 'it breaks'
description.  Please provide more details.

Issue 2: System->Preferences->Screen Resolution
If that fails, it's time for you to get friendly with a little file
called /etc/X11/xorg.conf (but please, BACK IT UP before making any
changes so you can revert if X fails to start)
