I just installed an older version of redhat (7), I have a book that I'm using but I've encountered a prob, when I'm in the xfree system the windows are clear except for text and icons, and they leave ghost images when moved or changed, I like linux but I have not found the answer to this prob, any suggestions would be great, btw I have an older trident vid card, but linux recognizes it. don't know if that helps
