To me that nothing printed is reasonable as this implies that drm driver didn't perform any real brightness setting in respond of attempting to set it. This is weird but possible, there's breakage of something in the middle of the process in prior of driver was asked to set a value. :) I think we can rule out combination mode as it didn't take place and focus on the ACPI issue. From your log that's Intel opRegion bios relies on in order to communicate with vga driver (a memory region when you write some value, an interrupt is trigger automatically to notice vga driver to fetch the value and do something (like change brightness) accordingly). Would you please help to dump the ACPI for debugging? $ acpidump > acpidump.hex And attach the acpidump.hex .. Thanks a lot. :) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
