--- Comment #4 from Charles-Antoine Couret <renault at fedoraproject.org> --- With default option, after boot : [root at DiNozzo ~]# cat /sys/class/backlight/acpi_video0/brightness 20 Same conditions, after pressure of FN down brightness key : [root at DiNozzo ~]# cat /sys/class/backlight/acpi_video0/brightness 10 I suppose the driver can write this file after that. ;) -- You are receiving this mail because: You are watching the assignee of the bug.
