That's not the exact one I used, but the instructions are all the same.

When I used ttmkfdir on the directory where I copied over my Windows fonts, it gave me a segmentation fault. It wasn't until about five hours later that I started actually having problems, which is weird, because I hadn't restarted or even logged out during that time, and everything was running fine. I think the last program I tried to run before having problems was Thunderbird, which crashed when I tried to open it. After that, nothing would work, except for KDE-based apps.
