AceLan, the patch first entered in the 3.6 series, the bug you linked is much older.
Daniel Vetter first mentioned the patch in https://bugs.freedesktop.org/show_bug.cgi?id=43577#c9, but there are no reports thereafter that claim that it causes black screens (these issues existed before the patch). ** Bug watch added: freedesktop.org Bugzilla #43577 https://bugs.freedesktop.org/show_bug.cgi?id=43577 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/806032 Title: Fn + F[89] does not work for controlling brightness on Clevo laptops (B7130, W150HRM) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/806032/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
