OK, then you're hitting multiple issues, as it seems.
The inconsistent value read from sysfs was addressed by my patch. But, I suppose that the main reason of the non-functional backlight is that the driver misdetected the backlight control over aux.
I refreshed again the KMP with a hack patch to disable the aux support. Please give it a try later again. This will show a line "XXX ext_caps=0x..." in kernel log.
IT WORKED!!!! Thank you for your time. I can now control the brightness with Fn Keys or the OS Slider in OpenSUSE. So the problem was with the aux detection. I know this is not a proper fix but it works. I hope you upstream this work to the mainline kernel or OpenSUSE patches?? -- You are receiving this mail because: You are on the CC list for the bug.
