My brightness control doesn't work with a fresh install of 12.10 (brand new laptop). It is set to the brightest setting when I boot up and when I try to change it, I see the notification bar come up but the brightness doesn't actually change. I've tried all the solutions I could find around the Internet but none of them work. Things I have tried include:

Editing /sys/class/backlight/acpi_video0/brightness

In /usr/share/X11/xorg.conf.d/10-brightness-control.conf: Option "RegistryDwords" "EnableBrightnessControl=1"

In /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor"

There is no xorg.conf file in 12.10 that I have found, so the solutions that suggest editing that file don't do me a whole lot of good.

I am currently using the Nouveau driver, but switching to the Nvidia proprietary drivers made no difference.

Any other ideas? When is this bug going to be fixed? With all the reports I've come across I would think it would get a lot of attention. Thanks.
