Xorg on LCD with DVI seems too sharp (nicer on PowerBook)

[Chris Shenton]

I've got a Dell 2405 LCD at home and work.  At work, it's driven by a
PowerBook with DVI and it's very nice.

At home, I'm driving it with DVI from a Dell with a built-in Radeon
card running FreeBSD-6.1-PRERELEASE.

  PCI:*(1:0:0) ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)]

There, it seems too sharp, too grainy, especially for text like
writing code in Emacs, reading docs with Mozilla, etc.

Any suggestions on how to soften it a bit?  I guess I don't understand
why the Mac display is comfortable but the FreeBSD Xorg display feels
so irritating.  Perhaps I need to use a different set of fonts or
something?

Thanks.
