Comment 30 for bug 1887190

It's a good question.

In my understanding, the Legion R7000 is the name for China of the Legion-5 15ARH05. In the Lenovo forum, the Lenovo employee has no access to the equipment and indicates it's a kernel issue, suggesting it used to work prior to 5.4 kernel. That looks strange.

Also in this thread a member of the Lenovo forum points out to a blog, unfortunately in Chinese, of a guy who may have found a workaround. I tried to google translate it but was not sure of the result to try anything :
