OP: Generally, if post length permits, you should edit extra information into your first post instead of replying to it. Some users run a canned search for threads with zero replies as a way of finding posts to answer. When you replied to yourself, you removed your thread from that list, even though you were not replying to announce that the thread was solved. Thus, they would no longer see your thread on the list of unanswered threads.

The best current way of setting X is with files into /etc/X11/xorg.conf.d

For now, you have to remove or comment out every thing, and follow Xorg/Guide.
