I have ubuntu 20.04, I can connect different bluetooth headphones, the audio works. But not the microphone.

Codec: Nvidia GPU 9e HDMI/DP
Codec: Realtek ALCS1200A

I have ubuntu 21.10 installed. I confirmed that I am using cgroup v2 by running mount, which shows cgrup2 on /sys/fs/cgroup type cgroup2.

sudo cgcreate -g cpu:newgroup  # or
sudo cgcreate -g all:newgroup 

it fails with error:

cgcreate: libcgroup initialization failed: Cgroup is not mounted

xrandr external monitor not being set as primary after screen unlock

Edit2: the solution is so much simpler with autorandr which is explained here: https://askubuntu.com/a/1130337/8 no more messing with scripts which never seem to run -- I still have no idea what I was doing wrong with the xrandr commands, but it doesn't matter anymore.


Edit: I still have some problem with triggering the xrandr command correctly at each login, because something I'm not understanding ...

What does the "DRI_PRIME=2 program-name" command do?
cn flag

I use DRI_PRIME=1 program-name for running a program via discrete GPU on a notebook computer.

DRI_PRIME=0 program-name and DRI_PRIME=2 program-name gives the same result: program is run via integrated GPU.

Does the following command has any different effects on different systems (for example on 3 GPU installed desktop computers)?

DRI_PRIME=2 program-name

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.
