For reference purposes, here's how to set that brightness in case of emergencies without the Fn keys:
Set the value of: /sys/class/backlight/acpi_video0/brightness to a value between 1 and max, where max is: /sys/class/backlight/acpi_video0/max_brightness Note that you can't just sudo echo it in there. (???) You'll need to pipe-feed it, e.g.: echo 15 | sudo tee /sys/class/backlight/acpi_video0/brightness -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1028518 Title: Fn keys such as brightness and volume stopped working after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1028518/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
