How can I simulate unplugging a monitor's HDMI cable and plugging it back in?
nc flag

This question is not about how to fix my system to work as it should. If you want to answer that question, see my prior question.

In order to get my three monitor system to work I have to physically unplug the monitor that is not working, plug it back in, and then do that again. This is inconvenient if not physically damaging my HDMI connector.

Therefore I'd like to execute a program that is the eq ...

After upgrading to 22.04 screen stays at a black screen when logging in
sz flag

I'm using a Lenovo ThinkPad P15s. I recently upgraded Ubuntu to 22.04, but after rebooting I can't seem to log in to my account, and the screen stays blank. I performed a system restore and was able to log in, but after rebooting I encountered the same problem. I assume that this update may contain some bugs. Is there an easy way to fix this issue?

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.
