I managed to get it to a point where the OSD popup was working and the keyboa= rd button showed up in Quick Settings, but it still wasn't changing the keyboa= rd backlight. After some more tinkering, I got it so the Quick Settings button would swit= ch between Off and Low, but it still wouldn't go to High. At this point, I hav= e no idea what's going on. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
