I can also confirm the bug on Ubuntu 14.10 on ASUS UX303LAB. $ sudo dmidecode -s bios-version UX303LAB.205 $ uname -a Linux UX303 3.16.0-33-generic #44-Ubuntu SMP Thu Mar 12 12:19:35 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
A possible workaround: I have screen brightness control through the system settings, but not through the Fn+F-keys. This works if acpi_osi=intel is in the boot parameters, or there is no "acpi_osi" mentioned. For example, only "quiet splash". If you install xbacklight from the Ubuntu repositories, the commands $ xbacklight -dec 12.5 $ xbacklight -inc 12.5 decrease and increase (respectively) the screen brightness by 12.5% (I picked 1/8th total, but another choice will do). So, in keyboard settings I mapped these commands to Alt+F5 and Alt+F6, which seems ok so far. Hopefully this will make things easier until a fix comes out. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1348890 Title: Asus UX32LN: Brightness keys Fn+F5 and Fn+F6 don't generate evdev event Status in linux package in Ubuntu: Confirmed Bug description: Hello Community, It seems brightness keys don't work with latest Ubuntu 14.04 LTS for laptop Asus Zenbook UX32LN. sudo dmidecode -s bios-version UX32LN.203 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1348890/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
