As more keys are registered with the latest upstream kernel, here is a reference of wrongly mapped fn keys :
What I see on the keyboard -> What the system sees Brightness down -> Battery Brightness up -> Sleep External/Internal screen -> Suspend Trackpad on/off -> External/Internal screen Volume - -> Volume + Volume + -> Volume - Mute -> 0xF8 ? Wifi toggle -> 0XF8 ? The rest is ok. Also note that the Fn behaviour is inverted (i.e. on this keyboard your are supposed to use the Fn key to access f1...f12 and not use the fn key to use special functions) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1217436 Title: Brightness keys are not recognized on Toshiba Satellite U840W To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1217436/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
