The command output will show 100% brightless, but it appears to remember the previous value, as if I go back to, say, 50% with "backlight 50" it presumably already thinks it's there and will do nothing. If I choose another value, whether higher or lower, it will correctly set that new value, after which backlight(8) will report that value. So: # backlight 50 -> unplug and see backlight brighten # backlight brightness: 100 # backlight 50 -> nothing happens # backlight brightness 100 # backlight 40 -> backlight goes to 40% # backlight=20 brightness: 40 # backlight 50 -> backlight goes to 50% this time # backlight brightness: 50 --=20 You are receiving this mail because: You are the assignee for the bug.=
