You have been subscribed to a public bug:
I have screen brightness set to about 30% in gnome-control-center's
Screen app.
After I first login, the first time I press a brightness adjustment key,
brightness is reset to 100%.
Subsequent adjustments work correctly. It appears that the adjustment
script is not reading the correct setting the first time, but stores it
for subsequent adjustment events.
Another behaviour probably related to this: if I say turn the brightness
down to minimum and then switch to a guest session via the indicator-
session menu, when I switch back the brightness is set to full. If I
press either brightness adjustment key, it immediately resets the
brightness back to minimum. So upower is using its locally stored
setting, but it does not match the current setting.
