Don't be mislead by the moniker Xtreme Graphics. It was a good bit better than
Intel's previous graphics iterations, but xtreme would be best applied in
conjunction with the descriptor "weak". It wasn't much better than simply
tolerable when new. It doesn't help to have it with a Celeron, Intel's bottom of
the line CPU and trivial CPU cache. Here are some specs from a Pentium IV (I have
no Debian on either of mine.):

Running KDE3, it's tolerable for essentials if no faster machine is available,
fine for running OS/2 or DOS.
