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. I ran
xev, and I'm 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.
