Lenovo IdeaPad 5 Touchpad not working in Ubuntu 21.04
my flag

So I've bought a Lenovo IdeaPad 5 and installed Ubuntu 21.04 on it. While a Mouse works just fine, the Touchpad does not. I've tried numerous methods I've found on YouTube and different forums. I edited a lot of things in grub and updated it, rebooted the laptop and also tried the kernel method but unfortunately nothing works.

I have recently installed Kubuntu 21.04, and upgraded the kernel manually to version 5.14 because the wifi adapter was not recognized first and I read in a forum that it has been solved in the new kernel (it works now indeed). If I understand correctly, the updater program Discover wants to install earlier kernel versions now, i.e. Linux headers generic 5.11.0.34.36 -> 5.11.0.36.38 etc. How to procee ...

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.
