Did this issue start happening after an update/upgrade? No. Was there a prior kernel version where you were not having this particular problem? No.
Also, I finished testing the mainline kernel build, version 4.18-rc6. The issue is still present. I have marked the bug as requested. ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1784008 Title: brightness keys incorrectly mapped for ProBook 455 G5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1784008/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
