My experience with Open Source/Free Software has been very positive in the year I have been using it.
I am very disappointed with the display problems I am having with RH8. I am not sure if this is a user problem(me), Monitor, video, or something else. I have vast amounts of troubleshooting experience, but limited experience with RH. I have used the built-in configuration tools, vi to edit the config, different hardware, and reinstalling.
Why can't RH spend more time on building a quality GUI that isn't so difficult to troubleshoot and improve other elements, instead of releasing a new version every year? One of the reasons Mac has such a loyal following is they release very stable products.
