Thread: Screen Brightness - No Steps


when use keyboard change brightness on laptop jumps straight minimum maximum (or maximum minimum if decreasing) without stopping.

if use slider brightness in ubuntu (under settings), can drag it, when let go slides straight maximum or minimum.

way control brightness @ level in between maximum , minimum "echo x > /sys/class/backlight/acpi_video0/brightness". x = value 0-7.

ideas what's wrong?

edit: using ubuntu 12.04, 3.2 kernel.

edit 2: annoying formatted , reinstalled. fixed problem... until updated. 1 of updates causing don't know 1 (there on 300 after new install).

ok seems new kernel (3.2.0-27) causing issue. since it's "important update" should put inconvenient brightness controls?
safe stay on older 3.2.0-23?
