Public bug reported:
This bug originates from bug 173652. (Unable to adjust screen brightness
on recent Sony Vaio notebooks, Intel GMA adapter).
The screen brightness now works, but runs through very poor steps.
Comments from the other bug may explain this best:
"To be honest, with the patch I'm using in stable, I get 20 steps. I
find this just a slight tad to many. mostly because I feel it should
have a little better flow. 19 to 20 goes from I'd like this a little
darker to completely black. Perhaps 15 would be a good number?
I'll have to grab an a4 cd and check it out. For me I know it'll be a
matter of how well it works as opposed to working or not."
"On Jaunty with latest updates I now get 9 steps for the backlight with the
Fn key combination.
When I installed (Alpha 3) there were only 5 steps, so some update changed
it.
9 steps (while an odd number) is working a lot better now, and much more
usable because the difference between the steps is not so drastic.
I think its working very well now."
It sounds like the 10 to 15 steps is good, my personal vote is for 15.
My other issue with what's left is that the last few steps in the
process go from slightly dark to completely dark.
I don't have the test environment at my disposal at this point but I
will get further information attached asap.
