Binary package hint: xorg
I have early 2006 Macbook (1.1) changing the LCD brightness using the keyboard keys previously resulted in smooth brightness changes (from 0% <-> 100%). I've upgraded to maverick yesterday and the "minus" brightness key when going from 100% results in flickering cycles (100% -> 0% -> 50% -> 0% -> 100% -> 0%).
This is a regression from Lucid and Karmic, while Jaunty and before had the same flickering.

Hey Dmitrijs,
Thanks for testing maverick during its development period. Unfortunately it looks like this bug report didn't get attention during the maverick development period. But I see there's not been more comments on the bug since the release, which makes me wonder if this is still an issue for you?
If you've not seen this issue since maverick's release yourself, it may have been solved by kernel or X or other updates that occurred late in the release; if so, would you mind please closing the bug for us? Go to the URL mentioned in this bug report, click the yellow icon(s) in the status column and set to 'Fix Released'.
If you no longer have the hardware needed to reproduce the problem, or otherwise feel the bug no longer needs tracked in Launchpad, you can set the status to 'Invalid'.
If you are the original reporter and still have this issue, just reply to this email saying so. (Or set the bug status to Confirmed.) If you are able to re-test this against 11.04 Natty Narwhal (our current development focus) and find the issue still affects Natty, please also run 'apport-collect <bug-number>' while running natty, which will add fresh logs and debug data, and flag it for the Ubuntu-X development team to look at.
