Laptop can't see external montior's maximum resolution

I've got a Lenovo IdeaPad 5i 15IIL05 with Intel UHD graphics, running Ubuntu 20.04.1. I want to connect it to an external monitor (Acer Gaming Nitro VG270U) via HDMI.

When connected, it does work - however, the highest possible resolution the system suggests is 1920x1080, when the screen itself supports 2560 x 1440. It is definitely not a problem with a cable or the monitor itself - when connecte ...

Proper Way To Use prunepath command

I'm taking an Intro To Linux course, I'm not completely unknowledgeable with Linux, because I started using it as a main OS before I started the course, however, the textbook kind of confuses me with wording how they exclude files, directories and filesystem and doesn't give a proper example on how to use it. To keep this a Ubuntu related question and not a "Linux in general" question, how do you use th ...

Can I display UTC offset rather than local offset in the desktop calendar applet?

I have configured some world clocks in the Gnome Clocks application, and they appear on the Ubuntu desktop calendar as expected, see below. (I don't know the correct name for the "desktop calendar" applet.)

However, the timezone offsets are relative to local time, so right now it displays:

New York -5
UTC -1
London 0

instead of:

New York -6
UTC 0

I habitually read offsets as UTC offsets, so t ...

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.
