Those messages are harmless. I believe a scancode is being produced for the Fn key, but there's no need to be handling it.
The same changes for Toshiba hotkey handling were introduced upsteram in kernel version 3.4-rc1, so that's an indication that these changes are likely to blame. Checking 3.2.0-21 or earlier of the kernel for precise should confirm it. If you find that using the older precise kernel helps, please do the following while booted with that kernel. Install the input-utils package and run 'sudo lsinput'. You need to find two devices in the output, one named "Toshiba input device" and another named "AT Translated Set 2 keyboard". Note the device numbers for both of these (lsinput will show /dev/input/event<n>; <n> is the device number). Starting with the Toshiba device, run "sudo input-events <n>", then press the function key for the brightness. If you don't see any output, do the same for the AT keyboard device. Let me know which device shows events in response to the brightness keys. You can exit input-events with Ctrl+C, or it will time out after a few seconds of inactivity. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/979268 Title: Toshiba Satellite L30-134 adjust backlight using function keys does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/979268/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
