A newer version of the kernel with a different set of bugs? :-)

In the network control panel you can set an interface to be (or not)
active on boot. Or you can
edit /etc/sysconfig/network-scripts/ifcfg-eth0 to have "ONBOOT=yes" in
its defined configuration. 

You could also activate NetworkManager to automatically detect lost and
recovered network connections (useful if you move your machine between
networks). Do "/sbin/chkconfig NetworkManager on" and "/sbin/service
NetworkManager start" to stat the service (you'll get an applet in the
panel that shows you the status).

Hmmm, the fuzzy quality is probably anti-aliasing (which probably is not
being done in xterm). 

There's two things (well, probably more) you can to to optimize font
rendering - you should be able to find plenty of articles through
google. Probably the most effective is to rebuild freetype to have the
byte code interpreter enabled (it is disabled in the Fedora build due to
patent problems with the hinting method). Get the source package,
install it, edit the spec file to enable the byte code interpreter,
rebuild (possibly up the release) and install. 

This will make freetype use the font hinting included in the fonts
themselves (if I remember correctly). It does make a difference. 

Hmmm, I think the Liberation fonts are installed by default in Fedora 7
but I don't know if they are used by default. These are free fonts that
have the same metrics as the Microsoft fonts so they will/should/may
render the same as in other platforms.

Nope, first time. 

Double weird points because it happens on both Windows and Linux. Would
seem to point to a hardware issue except for the fact that it happens on
two different machines!
