[Jaunty] Screen brightness adjustment sluggish

[Chris Lasher]

In Ubuntu 9.04 (Jaunty), compared to Ubuntu 8.10 (Intrepid), screen brightness adjustment feels quite sluggish. The increments are very small, the time between each adjustment is a bit too long, and there's no acceleration (e.g., consistently holding down the screen dim/brighten button doesn't adjust more rapidly the longer it's held).

NOTE: This may not be Mactel specific (e.g., it could be the new GNOME behavior), but I'm reporting it here since I can not verify for other hardware, and am using the Mactel drivers for screen brightness adjustment.

I confirm this behavior on a MacBook Pro 5,1 under Jaunty 64-bit with latest mactel packages (=drivers) installed.

To add some information for those look into this bug... The backlight is enabled by the applesmc module. The "mactel packages" being referred to are some PPA packages that are available for some intel Mac users. Details here:
