No, it is not due to a regression, every Linux version that has ever
been on it has had the same problem and will continue to have the same
problem until a patch is submitted. No updates have made a difference.
The problem is no doubt due to the Nvidia graphics on the laptop. I
believe the Nvidia chipset handles the screen brightness. I believe it
has a geforce 105M.

When I say brightness, I mean the actual backlight getting brighter and
dimmer.
