After some investigation, it seems like the actual bug has nothing to do with keymap.
Fn+F5/F6 actually does work. Keypresses are recognized as ACPI events (see comment #1 above), and keymap does not show anything ever. Currently brightness level goes something like this: Left hand side: what NotifyOSD tells me Right hand side: actual brightness, compared to what I see in Windows (approx) 50% = very bright - probably 100% -- cannot go above this level! 40% = about 30% brightness 25% = about 50% brightness 10% = about 70% brightness 0% = about 10% brightness And then, after reaching 0%, when I press brightness down again, Brightness control stops responding to any of my input (it seems to "freeze" for a while). So the current workaround would be to make sure that you don't press Fn+F5 too many times and just live with mismatch of brightness levels. -- brightness hotkeys don't work as expected, asus ul30a https://bugs.launchpad.net/bugs/543294 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
