Did the backlight used to go off in a previous > > release? > For me, the problem has always existed. But before, I used the PBButtonsd > daemon (http://pbbuttons.berlios.de/). This daemon switched off the backlight > putting the level brightness to zero. > But I think the radeon driver should switch off the backlight alone without an > other daemon because all "power manager" programs (like gnome-power-manager) > use the DPMS features to control the switch on/off display. > I agree, I just don't know how apple does it. > > > I suspect apple has the backlight wired up some non-standard way. > Yes, I agree with you. I also read about this on internet but I can't find the > article again. > > How can I help you to find a solution ? > if you could use radeontool from here: http://cgit.freedesktop.org/~airlied/radeontool and dump the regs when the backlight is on and when it's off and attach the dumps, I'll see what I can find. as root: ./radeontool regmatch '*' > blon.dump ./radeontool regmatch '*' > bloff.dump -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
