[Bug 1180749] AMD Ryzen 4800H Renoir APU brightness control not working as found in some Lenovo Legion 5 15ARH05

http://bugzilla.opensuse.org/show_bug.cgi?id=1180749 http://bugzilla.opensuse.org/show_bug.cgi?id=1180749#c25 --- Comment #25 from Takashi Iwai <tiwai@suse.com> --- 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. -- You are receiving this mail because: You are on the CC list for the bug.
