I have a home server running Ubuntu Server 20.04.3, I use it to host a Docker Swarm, and a couple of KVM guests. Yesterday I rebooted it (as I've done many times before) and since then I've noticed that the fans are quite loud.

Just now (about 24 hours later) I used top to take a look, and I discovered 10 instances of the following command:

Ubuntu 21.04, Wayland, mouse middle click is not working
cn flag

It seems like the middle click does nothing at all. If I go to Settings > Mouse & Touchpad > Test Your Setting and try middle clicks, I get no feedback at all.

Running xev also gives no event for middle click (scrolling works).

What's up? How to fix it?

Mouse is Logitech M510 btw, if it matters.

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.
