[Bug 1225672] [NEW] Brightness adjustement doesn't work

 

You have been subscribed to a public bug:

On Toshiba R700, Ubuntu 13.04 updated, I can't adjust the brightness
(via keyboard or parameters). The modifications have no effect at all.
It's permanent and last since a while: it worked at the beginning, and
as I don't modify this parameter very often, I can't say when it
happens.
