Here we go again, more Linux madness.

I'm between jobs so I got a little time on my hands. While I am waiting for the Fedora 7 DVD 64-bit to magically appear on my door step, I downloaded another distro. Mandriva 2007 Spring KDE 64-bit iso. and guess what? It all fits on one CD. I couldn't wait to load it, install it and though I didn't like the colors, it was very good. Until, after I did the first system software upgrade. I rebooted the computer and got a black screen with a working cursor on it. I couldn't input commands or anything. Being still by lack of geekness, a newbie, I really have no clue what went haywire. I am a bit disappointed because Mandriva like Fedora 7 is a bit cutting edge in terms of new stuff that will eventually show up in all Linuxes. Mandriva has virtual machine services installed, so I hear. I was going to check that out. Mandriva also has this desktop paging system called Metisse. It is 3d or pseudo 3d as some say, it blows away Vista's Aero. It supposedly doesn't even need the special video drivers for nvida and ati cards. Metisse is not in the Ununbu program repositories. No one has compiled it for .deb yet, as far as I know. It has all kinds of snazzy features for the desktop. I was going to check all this out when, my screen went dark. I don't know if I have the heart to dig deeper into this problem, I am not the first to have it by internet accounts. Meanwhile, in another partition of the same machine my Kubuntu is working just fine.
