I'm running ubuntu on a 390X.
Is that a setting to get gnome to default to a smaller screen? I am 
running the full blown Ubuntu and have been for a few weeks now.

Add acpi=force to the kernel paramters at boot and that will fix the

Sound is fine with my unit, however, I have never booted with no cards 
inserted, there is usually 3com card in there and also a Dlink 650+.
