Why are you using the CDs instead of the the DVD? Seriously, unless you have a really good reason don't use the CDs. The DVD is much easier and vastly faster (40mins vs 3+hrs). The CDs should be used if you are having difficulty with hardware compatibility, for customising partitions, etc.
Simple answer: Using an older PC to evaluate LMCE prior to working with my live boxes. Didn't have a DVD player in it at the time. I believe I figured out where the problems might be. I'm wondering if the OS updates I ran were the problem. There is mention that running OS updates on top of LMCE will screw things up. Anyhow, I decided to reset and try again.
New path: I downloaded the DVD iso overnight, installed a DVD drive, and ran the DVD installer this morning. Things started off well. Kubuntu completed and rebooted. The LMCE setup ran and I prompted with its basic questions. This all went off without a hitch. However,at this point, the install seems to be stuck in a loop with a dialog reporting the error: "Orbiter failed to initialize OPENGL". The only option isOK. After a few OK's it became apparent that I was stuck in the aforementioned loop. So, I figured I'd return here to see what I might try next.
Thanks, in advance, for any suggestions.
