I finally bisected a acpi video regression on my aspire 5720G
Reverting commit
"ACPI video: support _BQC/_BCL/_BCM methods that use index values"
commit 1a7c618a3f7bef1a20ae740df512eeba21397fa5.
Makes it work, otherwise /sys/class/backlight is empty, and I get error
messages when I press hardware keys to change brightness:
"ACPI: Failed to switch the brightness"
Best regards,
Maxim Levitsky
