Title:
Can't adjust brightness on MacBookPro9,2
Status in linux package in Ubuntu:
Confirmed
Bug description:
Since installing updates to Lunar roughly a week ago, there has been
no way to adjust the brightness on my MacBookPro9,2. There are no
brightness controls in the GNOME system menu (in the upper right) or
in the Settings app. The brightness keys also don't do anything.
The issue occurs on Wayland and X11 GNOME sessions.
It had previously worked fine in Lunar and earlier Ubuntu versions.
I tried clean installing Lunar (and updating) with no change.
I tried booting to a 22.04 live session, and brightness controls do
appear and work normally.
