Hi, I have now gone back and tested kernels back to 2.6.32, the kernel that was used in Ubuntu when this laptop was released. It seems I remembered incorrectly, backlight control has never worked properly on this laptop.
Backlight control did not work on any of the kernels I tested. I tested the following kernels: - 2.6.32-69-generic - 2.6.38-02063808-generic - 3.0.1-030001-generic - 3.11.0-12-generic - 3.11.0-26-generic - 3.13.0-32-generic - 3.13.0-34-generic - 3.13.0-37-generic - 3.13.0-37-generic - 3.18.0-031800rc4-generic It is possible that the problem is the same as for the UL-80VT: https://bugzilla.kernel.org/show_bug.cgi?id=66501 ** Bug watch added: Linux Kernel Bug Tracker #66501 http://bugzilla.kernel.org/show_bug.cgi?id=66501 ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1392016 Title: [Asus UL30VT] Backlight control does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1392016/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
