Ubuntu 20.04 LTS dual boot freezes before login, cannot enter TTY (likely a nvidia drivers problem)
cn flag

I've been breaking my head on this one for almost two weeks now and I really don't know how to solve this, I've followed dozens of askubuntu questions, bot none seems to help solve my problem.

Since two weeks my Ubuntu 20.04 LTS won't boot to login anymore after it autoinstalled some updates. It is most likely driver related, because booting to an older kernel with the default graphics driver wor ...

Set or override default amplitudes for applications
pw flag

When the zoom audio application launches or changes audio state, it's levels are set very low in pavucontrol. I turn them up, but they don't stay up. Any wobble in audio settings, and everything is turned way down again. How can I (re)set default amplitudes so it's a normal volume?

I am on ubuntu studio 20.10 and pulseaudio 13.99.2

so, I'm a Windows user coming to Ubuntu for emulation. Installation was tough since my monitor is VGA and my system has both an AMD CPU and GPU so I had to to it in 640x480.

Ubuntu-MATE 20.04 - missing Network Connections

I have a shiny new Lenovo P14s 2nd gen ( installed with dual boot, Win10 and… ) Ubuntu MATE 20.04.2 LTS. And I can't connect by Wi-Fi. For some graphics-related driver issues (a little too shiny new after all for Ubuntu 20.04 it seemed) I did upgrade the kernel to 5.12.4 generic, but this is probably not relevanthere.

I can't see any network connections. Neither in the top panel (where a respective pu ...

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.
