Message-ID: <20100312174248.GA4920@sgi.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.20 (2009-06-14) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org A long time ago, my laptop (Sony VAIO VGN-FE550G) had xbacklight steps that were very fine grained and could step down to the point where text was difficult to read at the edges of the screen. This was beneficial for preserving battery life. An update a couple years ago of something, and I don't recall what, turned the steps into very coarse steps (1/7). How would I start going about finding the restriction on the number of steps and increasing it to a larger value? Thanks, Robin Holt
