[Bug 1186896] AMD Ryzen 7 4700H Renoir: brightness + ext screen don't work

http://bugzilla.opensuse.org/show_bug.cgi?id=1186896 http://bugzilla.opensuse.org/show_bug.cgi?id=1186896#c17 --- Comment #17 from Takashi Iwai <tiwai@suse.com> --- OK thanks, it's now clarified. So the problem on Leap 15.3 is the boot problem. And IIRC, the same problem persists on the latest 5.12 kernel from OBS Kernel:stable:Backport repo? Did you try 5.13-rc kernel in OBS Kernel:HEAD:Backport, too? And, if you boot with nomodeset, does it still hang? (i.e. whether it's a problem of AMDGPU or else.) -- You are receiving this mail because: You are the assignee for the bug.
