Increase the preferred number of screen brightness steps to 20.
Review Request #122283 - Created Jan. 27, 2015 and submitted
Currently (10 steps preferred):
After the patch (20 steps preferred):
See https://todo.kde.org/?controller=task&action=show&task_id=829 for reasoning.
See https://git.reviewboard.kde.org/r/119597/ for the steps logic explanation.
Tested the new logic using a script to simulate different maxValue values (see the links above).
Did not test on the actual notebook, but it should work (current logic works), only the numbers are changed.
Sorry for the delay, I haven't had the means of testing it, but now I managed to get the X server use the intel backlight interface instead. Could you rebase this patch to current master? It didn't apply.
