Interesting point about xorg-x11-drv-ati - I will try that
on my problematic machine (I think it has an ATI card).

Indeed, my other machine that upgraded OK did indeed
already have xorg-x11-drv-ati-6.14.2-7 installed (and
has an ATI card).


Re the gnome-screensaver issue, I may have clouded
the problem in my reporting of it.  To re-iterate:

Machine A *had* gnome-screensaver installed at it
upgraded fine.

Machine B *also had* gnome-screensaver, but wouldn't
upgrade xorg-x11-server until I *removed* it (gnome-
screensaver).

Thus, rather than being a "dependency", it was actually
a conflict - or rather an "anti-dependency," to possibly
coin a phrase.


However, from both my own experiences on my
two machines and others' on theirs, the presence or
absence of gnome-screensaver doesn't appear to
have a difference on the actual problem of failing to
load X.

It looks like Mark may have hit the nail on the head
by identifying the ati-driver.  I will try on my second
machine here and confirm whether it works for me
as well.
