For me switching terminals does not help, but switching the background
light off and on back helps (Fn+F1 repeatedly then Fn+F2). The weird
thing is that with kernel 2.6.9 this problem was not present and now
the level 1 of luminosity is not really level 1 when coming back from
0 luminosity, while when coming from level 2 the behaviour is normal.
