Comment 8 for bug 204768

It's better but still not it. That's what I get now :

Warning: in getBrightness(): org.freedesktop.Hal.Device.PermissionDeniedByPolicy: org.freedesktop.hal.power-management.lcd-panel no <-- (action, result)
Traceback (most recent call last):

    if level == self.getBrightness():

    if self.old_b:

    binary = os.path.realpath(os.path.join(os.getcwdu(), sys.argv[0]))

Original exception was:
