I am totally new to this. I installed Absolute Linux 12.2.0 on a Dell Optiplex Gx150 pent III. Just a little under a gig hard drive. It goes through the boot sequence, and then the screen is black with a mouse pointer, then flashes weird color horizontal lines, and that's it. It does nothing when I hit ctrl alt F1 etc. I have searched and searched for a solution...but I don't know enough about it yet to know what to do. Any ideas?
