How does one diagnose a hardware vs software problem with a laptop keyboard backlight?

I have Ubuntu 22.04 on a Dell Inspiron-7779 laptop. My keyboard backlight began to work intermittently and then failed completely. I'm trying to work out if this is a software issue or a hardware issue.

I could not find a backlight option in BIOS, but I am able to control the theoretical light level using the keyboard (F10) and CLI (brightnessctl) in Ubuntu:

Night light not working with any Nvidia drivers, what can I do?
fr flag

Recently I approved an update through the snap store, and ever since then the night light doesn't work with any nvidia drivers. I had been using the 515 version, but it's disappeared from the list of additional drivers.

I've had to resort to using the Xorg driver, but it makes the fans go crazy, even for simple things like youtube videos.

Is there any way to solve this?

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
