So there are only 10 levels that actually works, while you can get 20 from reading /sys/class/backlight/acpi_video0/max_brightness, right? > So my conclusion is: The maximum brightness "comes to early". The upper 10 > brightness levels are skipped. Yes, ACPI does support 21 levels on this laptop. Please attach the result of "cat /proc/acpi/video/GFX0/DD02/brightness". and the content of /proc/acpi/video/GFX0/DD02/brightness after set it to some value lager than 10. -- 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. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
