There are replacement ACPI video options, but they seem to be rarely implemented because the system vendors assume the video driver will do the job. Also even if they had it wouldn't be implemented in the 64bit kernel. > architecture or to provide DPMS support in the FBDev drivers. There is some code from PPC for that, but it is generally very PPC specific. Backlight control also varies a lot so it would likely need tweaks for most laptops. Or just run a X server. It also doesn't get this right always, but at least sometimes. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
