Where is my /proc/acpi/video interface? Can't find it!

Hello!

I'm using a custom kernel. (2.6.23.8) For my xorg config I need a /proc/acpi/video interface (the nvidia driver need this interface).
I searched in the kernel config, but in Power Management / ACPI there isn't a "Video" Option.

How can I active this interface?

Thanks for your help!

Best regards,

Flasher

Hello,

I had the same problem a while back.  You have to go into Device Drivers / Graphics Support, and turn on the first option, "Backlight & LCD device support".  Under that option, choose "Lowlevel backlight controls".  At this point, the video option should magically appear in the ACPI section.

Works for me.  There may other dependencies I don't know about.
HTH,
peart.
