UBUNTU correctly indetifed the SIS-530 but guess didn't know what parameters to
pass to it. I think I need to change the refresh rate and the article on GRUB
didn't seem to address that. GRUB file would only accept numbers for row/col,
like 80x43.

It's interesting too that the screen saver display is nice and clear but the
normal display is terrible

With Puppy Linux if I use Xorg and their "generic driver" it works o.k. and in
that case it's 1024 x 768, 56Hz Horiz and 71Hz Refresh. Also if I use Xvesa
there is no problem.

Wonder why UBUNTU didn't use Xvesa which seems to be more trouble free, at least
for me.
