http://askubuntu.com – Installed 12.10 on old laptop with 1 gig of ram with a 20 gig hard drive. All I get after logon is a purple screen and mouse. I can't seem to get it to run. I also tried to install it using the windows installer on a drive with windows xp and had the same results. I am about to give up on Ubuntu altogether. (HowTos)
