[Bug 540333] Re: Brightness hot-keys don't work on Samsung NC10
Closing since the brightness control itself works starting with Karmic as long as you've upgraded your BIOS to at least v.11CA. Please see the link in #23 for alternative solutions if you don't want to upgrade your BIOS. However, there are related issues which don't affect the brightness control itself: Oneiric users will find following bug 810093 useful. The issue about completely enabling/disabling baclight (eg screen on/off) with Fn-F5 button is tracked at bug 296489. ** Changed in: linux (Ubuntu) Status: Triaged = Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/540333 Title: Brightness hot-keys don't work on Samsung NC10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/540333/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It would be helpful to have a trace of the kernel backlight functions.

I can only speak for the brightness buttons. It worked like a charm in 9.04 even with the old BIOS. In 9.10 nothing happened. After upgrading to the latest BIOS the keys functioned again.

I need someone to help me debug this. Please do the following: $ /lib/udev/findkeyboards You'll see something like USB keyboard: input/event5. We are interested in the input/event# part. Next: $ sudo /lib/udev/keymap -i /dev/input/event# Where # is the number determined from findkeyboards. Press all the keys that are not working correctly once. You should see lines like scan code: 0x7000E key code: volumeup. Copy and paste each line here, with a note on what each key code *should* have registered as. For example, if the brightness key was showing as volume up like above, this should be pasted here: scan code: 0x7000E key code: volumeup (should be brightness up) With this information I should be able to determine what is going wrong.
