i can't change my screen brightness by pressing brightness keys on the keyboard, but they change through
/sys/class/backlight/acpi_video0/brightness. so i started to diagnose the issue, ran
xev and trying to see what happens when i press
Fn+F6 which are brightness controls, and xev didn't show anything. i must note that it notifies my when i press volume controls, for example.
F6 keys working? yes, but not when i press them with
do i have any entry in
xmodmap for brightness? yes:
keycode 232 = XF86MonBrightnessDown NoSymbol XF86MonBrightnessDown
keycode 233 = XF86MonBrightnessUp NoSymbol XF86MonBrightnessUp
what's happening? and what should i do to correct it?
i'm using vaio s series laptop with kubuntu precise on it.
