--- Comment #50 from Zhang Rui <rui.zh...@intel.com> 2010-06-24 08:03:06 --- glad to know that the brightness control works well after all. :) IMO, this is a BIOS problem. I have refreshed the IBCM.aml so that you don't need to use custom DSDT any more. please try the custom IBCM.aml attached below, without custom DSDT. If it works, to workaround this issue, you can write a script to apply the custom IBCM.aml after boot automatically on each kernel that you're using. Note that this may require you to use a kernel with CONFIG_ACPI_DEBUG set in 2.6.33 and 2.6.34 and 2.6.35. But I have finished a patch to make ACPI debugfs I/F always built in even with CONFIG_ACPI_DEBUG cleared. i.e. in the future, you don't need to apply the custom DSDT and rebuild your kernel, just mount the debugfs and apply the custom IBCM.aml, for each new kernel you're using. :p -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
