If I try to load thinkpad_acpi (which is not loaded by default) I see this: 2013-11-29T10:40:06.161195-06:00 linux-k1fq kernel: [38371.765062] thinkpad_acpi: Standard ACPI backlight interface available, not loading native one I do not have a /proc/acpi/video directory. The 'intel_backlight' program works (sort of): linux-k1fq:~ # intel_backlight 90 current backlight value: 89% set backlight to 89% linux-k1fq:~ # intel_backlight 60 current backlight value: 89% set backlight to 59% linux-k1fq:~ # That seems... weird.
