Okay, so once I had everything figured out, everything was working on my
laptop smoothly, I go and mess it up, but it still really doesn't make
any sense.
I just bought an Eee 1000HE and the screen displays at a maximum of
1024x600 resolution, and needless to say, that leaves a bit to be
desired, especially because the Virtualization tools in Yast (among
other dialog screens) don't resize, so I can't click 'Next' or anything;
they're hidden below the end of the screen.
So, I tried changing the resolution in Sax2 and it worked, as far as I
could tell, I could see the dialogs at the bottom of the screen
(everything was tiny, but that's to be expected). After I finished I
used Sax2 again to revert back to the old 1024x600 resolution, and the
fonts were displayed... tiny.
Nothing in my fonts settings had changed at all, and when I try to
change it to make it more readable, one thing or another was left out,
when I force DPI in the configuration menu, Firefox fonts displayed
correctly, but popup dialogs, like a sudo prompt, would be huge. The
login screen, context menus, everything has changed because I changed my
resolution once, and I can't get it back; one thing or another is either
too readable or completely unreadable, reverting back to the default in
the KDE menu makes everything tiny again.
My questions: is there a way for Yast or Sax2 to probe my system
configuration as it did during install and adjust the settings to their
original default? How/why did this happen, and what can I do to prevent
it next time? How does everyone view windows that are too tall for the
screen and won't resize

?
Thanks for the help.
