Re: [radeonhd] xbacklight does not works again ?

2009/6/23 Vladimir Grebenschikov :

By some reason xbacklight now does not work for me again (it works in past).

In your case PANEL is controlled by LVTMA, not UNIPHY as in my case. So it's actually Christian's patch that disabled backlight control for you. Can you apply attached patch and compile radeonhd to test if this works for you? First I would like to know if you get _Backlight property in xrandr --prop If so: xrandr --output PANEL --set _Backlight 100 should work fine for you. Don't know about xbacklight tool. -- Rafał Miłecki
