I have now tested the very latest kernel, version 3.19 rc 1 (from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-rc1-vivid/), and backlight control still does not work.
The indicator does pop up and indicates increase and decrease in the correct way, but the actual backlight level on the laptop screen does not change. Furthermore, the function key to turn off the touchpad does not work, and doesn't even show an indicator bubble. ** Tags removed: kernel-bug-exists-upstream-3.18-rc4 ** Tags added: kernel-bug-exists-upstream-3.19-rc1 ** 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
