Well, I've gotten Slackware installed on this Dell Laptop that I'm borrowing. For those of you out there considering the total conversion to Linux, but are held up by the lack of support for games. You're not alone. That's been my entire reason for not ditching Windows has been for this very reason.
This evening, I came across a HOWTO for installing WineX. The HOWTO focuses on getting Half-Life to run.
Anyone that attempts this - before you begin, wget one of these scripts. They make life painless and carefree.
I have it working now. I can execute Windows binaries under Linux, but games are having issues. I'm guessing due to FreeType font-issues.
