Non-Slackware users need not read further! Thank you!
I downloaded the Linux quake binaries from idsoftware's site. I followed the instructions on the Quake HOWTO to install Quake 2. It was very easy to do it this way. Now Quake 2 only runs in software mode, even if I pick gl or glx with +set vidref gl...
So, I went ahead and downloaded the NVIDIA_GLX and NVIDIA_kernel tar files. I followed the easy instructions on how to install the nVidia drivers. Well, it didn't work! I got a message saying that insmod failed trying to load the nvidia.so or something like that. Why is it that these drivers do not require us to use './configure' and 'make' before doing 'make install'? I thought that was weird.
So, if you're using Slackware 8 and you've successfully got the nVidia drivers to work, I would like to hear from you.
