Ubuntu 20.04 not suspending on Alienware

I am running Ubuntu 20.04 on an Alienware 17 R4 with an NVIDIA GeForce GTX 1070. I recently did a software update which caused the system not to resume after suspend so I changed the driver from proprietary tested to proprietary server (version 460 on both).

Now the system won't suspend at all. It basically reboots when suspending from the GUI or terminal. I've tried editing the GRUB file by addi ...

Just today when I turned on my 18.04 computer it starts up and has the "Ubuntu" screen .. . then it turns purple . . . and that is all. There is no login.

need help understanding the ubuntu kernel source version numbering

Good day all!

I am running 18.04.5 for which ... uname -r ... yields 5.4.0-74.

I want to change one kernel setting and rebuild from the exact source to avoid issues.

In my steps to do so ... I issue this command:

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.
