[SOLVED] Screen brightness on ASUS K50IJ
I can't adjust screen brightness when I'm in tty. It's just works right in X
but when Im in a tty - it echoes, but screen would not really changes its brightness. And if I start X and adjust brightness to 100, in X it would be 100, but if I switch to tty, it immediatly drops brightness to 10. What it could be and how I can solve it? I'm not aware with VGA drivers well, so how to adjust its startup parameters (i mean /etc/modprobe.d/ files)?
echo -n 100 > /proc/acpi/video/VGA/LCDD/brightness
