Following https://wiki.ubuntu.com/Hotkeys/Troubleshooting :
Fn+F8 and Fn+F9 don't have any effect in xev Fn+F8 and Fn+F9 don't have any effect in acpi_listen Following /usr/share/doc/udev/README.keymap.txt : /lib/udev/findkeyboards outputs input/event4 Running sudo /lib/udev/keymap -i input/event4 , then pressing Fn+F8 or Fn+F9 does not show any key name. (but other keys work, eg Fn+F5 gives the sound keyname) ** Attachment added: "udev-db.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1041116/+attachment/3398884/+files/udev-db.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1041116 Title: Brightness hotkeys have no effect on Clevo laptop To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1041116/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
