No. :( > My guess is that hald is writing some magic value to something in > /sys/class/backlight/acpi_video0/ but I am not sure what it is... > right. please kill acpid, and run "cat /proc/acpi/event" attach the output after pressing the brightness up/down hotkey. please attach the dmesg output as well. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
