Filed a bug a year ago iirc, but nobody stepped up and finally fixed it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829641 Title: brightness keys on laptop don't dim the backlight To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxqt-powermanagement/+bug/1829641/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
