How to force change the Ubuntu splash screen (18.04)
br flag

All other answers refer to update alternatives. I have read and tried most of those solutions, here and elsewhere. It did not work.

I originally installed Ubuntu-Mate 18.04. Didn't like Mate, installed XFCE-desktop.

Ever since, I could not change the splash screen back to xubuntu-logo. (Currently on 18.04.6) I've tried (using update-alternatives)

No option to print line numbers in gedit
bs flag

I want to print line numbers from gedit, I know how to view them, of course. A previous answer to a question some years ago claimed that the option existed. But on my machine that option seems to have vanished: there is no top bar, no file tab etc. And why is it called 'text editor' rather than 'gedit'? I'm using 20.04.

If there were options then presumably I could also get it to show syntax colo ...

No sound from music software when using bluetooth headphones
eg flag

I linked a hearphone to an Ubuntu 21.04 machine using a dongle USB 5. From the figure below, it is clear that the connect has been established, and when I run the test sound, I can clear hear the test so the system communicates with the Bluetooth.

enter image description here

But, when I play music, for instance from Spotify or Clementine, there is no sound at all. When I use the cable, the music is played perfectly.

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.
