After changing it to legacy it still does not work. However, runing xbacklight -get I know get a figure (around 0.5), whereas before switching over to legacy xbacklight returned the mysterious string "nan".<br><br>
Anyway, xbacklight -set, -inc, or -dec does not yield any result.<br><br>Regards,<br>Khash<br></div></div><br>
