Hi, In the ongoing effort to split eeepc-wmi, and add support for Asus WMI capable notebooks, I found that some of them are able to control dispay output. Currently, asus-laptop, asus_acpi and eeepc-laptop are also all able to do that, and they use a simple sysfs file with a bitmask to do that. Now, I was searching the right, generic way to do that, and I found video_output class. The issue is that nobody, even acpi/video.ko, use it. So, what's the right way to do that ? Note, that in my case, I can't know what output are available, so anyway, using video_output would be a little tricky. But still, I'm not really comfortable adding another cryptic sysfs file, even with proper documentation in Docuementation/ABI/.
