I'm "cleaning" some unanswered questions that has no answer, but I found that an surprising amount of them solved their problems in comments. Is correct to flag comments and upgrade them to answers or should a proper answer be made. An example of this is "[Configuring Xorg.conf for i915 intel driver][1]" that one comment resolved the particular OP case, although other methods are available.
