This did not work. I already tried this but did it again to get the log
info you suggested. Lubuntu boots to black screen with only a mouse
cursor showing. If I somehow get a window open (maybe just a right click
to get a dialog or menu box) and drag it around the desktop with the
mouse then the desktop refreshes and shows up in the swath or path of
the dragged window - from doing this I get most of desktop to reveal -
but the desktop is incomplete. Any Lubuntu/Xfce window or menu I open
has deformed unreadable fonts with missing characters (ie. it's totally
messed-up looking). But if I open Firefox or the terminal it looks and
acts OK though. Here's log output:
user at user1-pchut:~$ cat /var/log/Xorg.0.log | grep -i uxa
[ 20.728] (**) intel(0): Option "AccelMethod" "uxa"
[ 21.081] (II) UXA(0): Driver registered support for the following

Thanks, any ideas appreciated.
