I have converted a PC into a complete Linux box using the KDE-Live CD and openSUSE 12.2. When I completed the installation yesterday, everything appeared to be normal except that the very last step, the auto re-boot, never occurred.
Today, when I boot up the machine I get a green open SUSE screen and then I get this weird “checkerboard” screen, and the expected normal screen never loads.
Welcome. It is a bit difficult to say but, if it did not reboot after the initial installation, you have an incomplete installation. 12.2 is a bit long in the tooth. So, if you can get hold of 13.1 (it needs a DVD for the Live versions as well as the full version), you will be better off. However, unless someone else has experienced the same symptoms and can give you more helpful advice, the procedure is probably the same: reinstall. Because you already have done most of the installation, the only partition it should overwrite will be the / partition; so it will take slightly less to get to the same point.
And please next time use a title of your thread different from what you use now. The title “Help for a newbie” does not povide any information about what your problem is. Thus it may be very likely that many people do not even read the rest of your request.
