Two questions regarding new Ubuntu 8.10 install

[Bob St John]

Folks,

I've got 2 questions regarding my new Ubuntu install:

1. The video is SiS 760 which apparently is not supported. The display
gets really messed up once in while. I had exactly the same problem with
a Fedora install. This is a known problem with Fedora, and the
resolution is to set the display drivers to "vesa". This worked in
Fedora, and I suspect it would work with Ubuntu. But I don't know how to
change the video drivers in Ubuntu. Is it possible to change the video
driver in Ubuntu 8.10 to "vesa"? How can I do that?

2. From my Fedora environment, I exported my Evolution settings, etc.,
for use with Evolution in Ubuntu. Evolution in Ubuntu seemed to
successfully import the settings, but now whenever I start Evolution in
Ubuntu I get a very quickly disappearing text box that I can't read. Can
someone explain what is happening and how I can fix it?

Thanks . . .
