Hello, nvidia 256.44 solved the problem of IDID detection (330m). But, when I enter on NVIDIA X Server Settings, the screen blinks on the first time when I enter in option.
The brightness control still doesn't work. I need to install nvidia-bl module (

On Xorg's log:
Initialized GPU GART.
ACPI display change hotkey events enabled: the X server is new enough to receive ACPI hotkey events.
ACPI: Error: Unable to find the brightness file path under /proc/acpi/video. The NVIDIA X driver will not be able to respond to ACPI brightness change hotkey events.
