According to the above investigation, it is a bios regression and not much we can do about it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1152544 Title: HP Envy 23 AIO - No way to dim display To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1152544/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1152544] Re: HP Envy 23 AIO - No way to dim display
I checked BIOS 8.10 (current version), and the ACPI device DD02 has _BCL/_BCM/_BQC methods unlike the BIOS that fixed it in https://bugs.launchpad.net/stella/hwe-stella/+bug/1023760/comments/13. If the ACPI device LCD0 is used (ex. calling its _BCM), the brightness will change accordingly. It seems newer BIOS from HP removed the original fix. I am not certain new BIOS update for this bug is possible since it is from 2012... ** Changed in: hwe-next Status: New = Incomplete ** Changed in: hwe-next Assignee: Alex Hung (alexhung) = Anthony Wong (anthonywong) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1152544 Title: HP Envy 23 AIO - No way to dim display To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1152544/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

According to https://bugs.launchpad.net/stella/hwe-stella/+bug/1023760/comments/13 , the backlight function should work on 12.04 if BIOS fixed this issue.
