<pre>I put a "regression" in the title, because I took an SSD from Dell Precision
7510, put it in Dell Precision 5540 and observed that backlight stopped working
- i.e. something that was working stopped. There is nothing to bisect, because
the loss of functionality occurred with device upgrade, not kernel version
upgrade.
Also, this is Fedora 30, not Ubuntu.</pre>
