At one point perhaps but I did set to VIDEO_CARDS to just nouveau before
starting to convert.

I have done this (more or less).  I have
EMERGE_DEFAULT_OPTS="--ask --deep --tree --verbose --jobs --load-average=3"

I did 
emerge --changed-use --update --keep-going world
and
emerge --depclean --ask --ignore-default-opts

The problem remains (after a reboot).
Specifically, gdm/gnome-shell puts up the screensaver giving the time in
big characters and I can't get rid of it using the mouse or keyboard.
I also tried
/etc/init.d/gdm restart
with no improvement.

thanks,
