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 driverConfiguring Xorg.conf for i915 intel driver" that one comment resolved the particular OP case, although other methods are available.
