Created attachment 844855 --> http://bugzilla.opensuse.org/attachment.cgi?id=844855&action=edit system information
I have just upgraded my device to Tumbleweed and now backlight brightness is stuck at 100% with no way to change it.
I have tried several methods, including xbacklight and Xfce settings. Backlight control used to work fine with Kernel 5.3 shipped by Leap.
I found a recent report using similar hardware that could suggest a regression in the kernel: https://discuss.getsol.us/d/6039-brightness-control-not-working-on-apple-dis...
I attached information about my system but please let me know what else I can provide.
