LinuxQuestions.org - Changing KDE's DPI Setting?

For some reason, I've been trying to make both Windows and KDE more plain, skinless, and boring. I guess I just feel like something simple for a change. I don't need it to mpress me, I already know the strengths and weaknesses of my two operating systems, and appearence isn't going to change that. I'm always getting tired of the GUI and changing it around, and I've found I don't get tired of a minimal win98ish look.

Windows is easy enough. I simply switch to Windows Classic style. Microsoft is very talented at making things look ugly. :p

KDE is a bit more of a problem. I love it's feature set, but it doesn't seemed designed for what I'm trying to do. Nonetheless, I've gotten everything the way I want it except for one thing. My DPI is set very high because I'm using 1600 x 1200. I would like to set my DPI so the fonts look about the size of Windows's default DPI setting (which I believe is 100). Unfortunately, there doesn't seem to be a DPI setting available in KDE to change.

I have very good up-close vision, and can read small text without a problem. Because the text is so large in KDE, it affects my screen real-estate, even if it does look nicer.

I've looked on the internet, but the only thing I've found that's relevant tells me to change an XServers file, which appears to do nothing. I'm wondering if there's a different way. I'd prefer a method that's user specific rather than one that changes the whole system, but a change that effects all users is the next best thing. Anyone know what I can do?

I'm using SUSE 9.3 with one regular user, which is logged in automatically with KDE on startup.
