(Get the code!)
This is a regression in 1.0 so setting the severity to major.
In the (hal based) 0.8 branch, when on a platform which handles the brightness itself (wether in the EC or in the kernel), xfpm was only showing the notification. It did the brightness change itself only in case nothing else could do that.
In 1.0, this is not the case anymore. In my case, (a Dell latitude E4300 and I guess a ThinkPad T61 which both have an Intel GMA965 video card) the brightness is handled by the ACPI video driver, directly with the card. There's no need for a userland application to set it itself. But xfpm still tries (and suceeds) to do it, so each time I press the brightness up key, the brightness level is upped twice. Same goes for brightness down.
I'm not too sure how you did manage to detect if the brightness was already handled in xfpm 0.8, maybe it was hal providing the information, but it'd be nice to have that back.
