--- Comment #110 from Peter Klotz <peter.kl...@aon.at> 2009-04-09 06:35:16 --- The final patch from comment #109 made it work perfectly! Thanks a lot Zhang for all your efforts! r...@asus:/proc/acpi/video/VGA/LCDD# cat brightness levels: 10 16 21 27 33 39 45 51 57 63 69 74 81 87 93 100 current: 100 Using "echo xx > brightness" works for all listed values. Using the brightness keys in Gnome gives this mapping between values in /proc/acpi/video/VGA/LCDD/brightness and /sys/class/backlight/acpi_video0/brightness. 100/15, 87/13, 74/11, 63/9, 51/7, 39/5, 27/3, 16/1, 10/0 The value of /sys/class/backlight/acpi_video0/brightness always matches the value of /sys/class/backlight/acpi_video0/actual_brightness. The visible screen brightness matches this values in all cases. Brightness can now smoothly be changed from low to high using the brightness keys. This leads to two more questions: * When will these patches go into mainline (I hope they will)? * Do I always need the customized DSDT or was it only necessary for debugging purposes? -- 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. ------------------------------------------------------------------------------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
