------- Comment #53 from jwoi...@physics.adelaide.edu.au 2009-03-12 15:53 ------- I was able to test 2.6.29-rc6 with your patch overnight on the S7020. After loading the video module (without fujitsu-laptop loaded and having not supplied "acpi_backlight=vendor"), /sys/class/backlight/ was completely empty. This shows that the patch has not caused video to take over the backlight control on the S7020 (something it shouldn't do because the S7020 only has a vendor-specific method available). So at least for the S7020 this patch does not cause any regression and can go forward. With fujitsu-laptop loaded (with video already loaded), /sys/class/backlight/ was populated. > grep . /sys/class/backlight/*/* /sys/class/backlight/fujitsu-laptop/actual_brightness:7 /sys/class/backlight/fujitsu-laptop/bl_power:0 /sys/class/backlight/fujitsu-laptop/brightness:7 /sys/class/backlight/fujitsu-laptop/max_brightness:7 This was the same regardless of whether "acpi_backlight=vendor" was specified. On the S7020 this is to be expected though. It would be good if this patch could now be tested on a machine which does have the buggy _BQC method. In the absence of this the patch should probably be applied to video anyway since at least in theory it seems worthwhile. I guess the only issue is ensuring it doesn't create regressions for other laptops. -- 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. ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
