So I have this old Dell Dimension 4700 that I want to use as a dedicated emulation box. For some reason though, parts of the Lubuntu greeter will appear (just the wallpaper and the mouse) for a few seconds, then turn into a black screen with a blinking cursor. When I try to log in with one of the other TTYs, it will show the "Welcome to Ubuntu" text for a split second, then go right back to the login prompt. I'm using Lubuntu 13.10. Any thoughts? It worked just fine before today.
Also, another weird thing. I tried to reinstall Lubuntu, but the installer kernel panics (and shows no useful information) as soon as I hit "Install" or "Try Lubuntu without installing".
