"Blank screen" after inactivity not really blank - mouse cursor stays
us flag

There is something wrong with the Power saving's "Blank screen". I've recently upgraded to 20.04 from 18.04. Blank screen is set to activate after 4 mins of inactivity. The problem is that the screen is going blank, but the mouse cursor is still shown and prevents monitor from suspending.

Any idea how to fix that?

Is there a video player that can solve these problems??

When I use VLC, its audio system is a little annoying. During speaking, its volume is low. During action and fighting, its volume is high. I have to adjust during the movie.

How to mount Apple's SuperDrive in Ubuntu 20.04

Maybe it sounds strange to use a USB-CD Drive nowadays. However, I need to get an old data from a CD and the only available CD-Drive was my old Apple's SuperDrive. Thus, I did the following steps:

  1. First connect the SuperDrive.

  2. Then, install the sg3-utils by:

    $ sudo apt-get install sg3-utils
    
  3. Then, to identify where the SuperDrive is use:

    $ ls -lt | less | grep sr

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.
