------- Comment #10 from tetrom...@gmail.com 2008-12-18 23:08 ------- With your customized DSDT: # grep . /proc/acpi/video/*/*/brightness /proc/acpi/video/VGA/CRTD/brightness:<not supported> /proc/acpi/video/VGA/DVID/brightness:<not supported> /proc/acpi/video/VGA/LCDD/brightness:levels: 100 90 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 100 /proc/acpi/video/VGA/LCDD/brightness:current: 100 cat /sys/class/backlight/acpi_video0/actual_brightness still reads zero. Backlight levels no longer roll over when incrementing. Instead, they roll over when decrementing :) In other words, if I decrement all the way down, backlight levels go 100 -> 90 -> 85 -> 80 -> 75 -> 70 -> 65 -> 60 -> 55 -> 50 -> 45 -> 40 -> 35 -> 30 -> 25 -> 20 -> 90 ! Also, could you please post the dsl source for your custom DSDTs so that I can repeat the changes you made on future BIOS versions, I can't get my copy of iasl to disassemble your DSDT.hex... -- 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. ------------------------------------------------------------------------------ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
