After updating to 2.6.27-11.23 from intrepid-proposed, my backlight keys stopped working altogether. They had been working perfectly since 2.6.27-11 but now this: cat /proc/acpi/video/VGA/LCD/brightness < not supported > After downgrading to 2.6.27-11.22: cat /proc/acpi/video/VGA/LCD/brightness levels: 100 60 20 28 36 44 52 60 68 76 84 92 100 current: 60 And the keys work perfectly again. It is likely related to this fix in the changelog: [ Andy Whitcroft ]
