[FIXED] after upgrade ACPI can no longer change my screen brightness

EDIT: never mind, it seems to of gone away now...i have no idea what happened, it stopped working randomly then started working just as randomly.....whatever...

Just yesterday i was using my laptop with arch linux with the brightness turned all the way down, as of course it saves battery

but now i turn it on today and the screen is at maximum brightness, and every time i try to change it it just says (in kernel.log) :

Sep  8 10:28:46 Polygon kernel: ACPI: Failed to switch the brightness
Sep  8 10:28:46 Polygon kernel: ACPI: Failed to switch the brightness

so...what got upgraded that broke this? does anyone else have this problem?

here is the past few days of my pacman.log: (it has some entries for kernel-my, a custom compiled kernel, but i get no screen brightness control on my custom compiled kernel, or the default arch one)

Re: [FIXED] after upgrade ACPI can no longer change my screen brightness

Do you happen to know what package broke this? I had this issue a couple weeks ago, and just recently it reappeared.
