Well, I checked my CD and everything checked out alright, so I went ahead and re-installed. Last time when I installed, I did skip loading LILO (I was hoping to eventually use GRUB). This time, I decided to use LILO. Now when I boot up, I choose either "linux" or "linux-gui" from the LILO boot menu, and then I see the text-based login screens pop up briefly, but then my monitor goes black and eventually goes into power-saver mode. It doesn't flash a "Frequency Out of Range" message, or anything like that. I've received this same result with both the "linux" option and the "linux-gui" option in LILO. I haven't tried the "linux-tui" option yet. I will try that tonight. Also, I was able to find a couple of posts in this forum about monitors going black, so I'll play around with some of those suggestions as well. If all of that fails, I suppose I'll try another re-install without LILO and use all of the same options from my original install (if I can remember them all). Thankfully, the VL install process is pretty quick, easy, and straight-forward. Now, if only I could get it to work!
Thanks again for your time and suggestions!
