Joseph, I can understand what upstream kernel version I should install to test.
http://kernel.ubuntu.com/~kernel-ppa/mainline/ My Ubuntu is Natty and I can see kernel builds for Oneiric, which are the latest ones.... Could you please point me to the correct version/link I should try? Thanks. ** Description changed: When I change LCD backlight value using Fn + left/right keys, the backlight change in 3 steps each time where it should increase/decrease at 1 step. + + NOTE: This bug just happens when I used OpenSource ATI video drivers. If + I use proprietary there is no bug. Max value is: root@cas-netbook:/home/cas# cat /sys/class/backlight/acpi_video0/max_brightness 9 Adjusting to lowest using keyboard and then starting increasing, I get: root@cas-netbook:/home/cas# cat /sys/class/backlight/acpi_video0/brightness 0 root@cas-netbook:/home/cas# cat /sys/class/backlight/acpi_video0/brightness 3 root@cas-netbook:/home/cas# cat /sys/class/backlight/acpi_video0/brightness 6 root@cas-netbook:/home/cas# cat /sys/class/backlight/acpi_video0/brightness 9 If I continue to increase with keyboard, the brightness value don't increase more then value 9. And, If I echo value 1 to brightness, increasing with keyboard, I cat the brightness and I get value 4, instead value 3 if brightness started with value 0. I simple don't get any event when I use the brightness key combination: Fn + arrow left/right.
