Hi Marco,
Hi,
Unfortunately, the results are, again, rather confusing. With sony-laptop.ko, after running backlight_fix once, actual_brightness has a nonsensical value -- 55.
It looks reasonable, don't worry about it.
I tried setting it to 5, and something actually happens this time - actual_brightness now reads 5 rather than -1, and the screen brightness actually changes -- but, alas, too much (if the brightness range is from 0 to 7, 5 should be rather bright, instead it looked more like a 2 to me).
This is weird, brightness level should be ~75%.
Further attempts to adjust brightness produced no result -- actual_brightness now tallies with brightness, like the video.ko's behavior, but the screen remained dim. Repeatedly running backlight_fix does not resolve matter either.
even more weird. I don't know if IGID has changed in the meantime, but there's something not working properly elsewhere. But definitely it's not a problem belonging to sony-laptop or video (which should be used because SBRT/GBRT methods, with 0 based values and 9 values range, pose problems with the current backlight device implementation in sony-laptop).
Anything else I can try?
