Sorry for jumping in the middle of the thread. I believe that this is also reported by Fedora users on a Lenovo Carbon X1 (gen 9) as: https://bugzilla.redhat.com/show_bug.cgi?id=2130699 So it would be good to add a: Link: https://bugzilla.redhat.com/show_bug.cgi?id=2130699 tag to the commit which ends up fixing this.
