That's up to the Ubuntu kernel team (I'm not a member) but the first step is to know if it helps.

Note that intel_backlight works for some of these laptops, and the backlight from samsung-laptop always work. The good news is that newer laptops have functional ACPI video device and won't end up growing this list.

One small addendum: just saw that the second device actually sometimes shows a different measurement. Something like 1.17W say when the first device is 1.25. In these cases it always seems to be a bit below the first device. When it mimics the third device, then it always seems to be spot on. When adding all reported devices to the reported baseline, the second 1W device is also needed to come close to the reported discharge rate. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/949221 Title: powertop incorrectly reports multiple display brightness devices to use power To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/powertop/+bug/949221/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
