Fix for me changing this in /etc/default/grub.conf
- GRUB_CMDLINE_LINUX_DEFAULT="splash quiet nomodeset" + GRUB_CMDLINE_LINUX_DEFAULT="splash quiet acpi_osi=Linux acpi_backlight=vendor"

Im using kernel from quantal but i think it will work with precise kernel (https://launchpad.net/~ubuntu-x-swat/+archive/q-lts-backport)
