Internal screen is "unknown", no other displays recognized

On Ubuntu MATE 22.04, I cannot use a secondary screen, and the first screen is also kind of weird. I can use the laptop and work on it, but when I open the "Devices - Screens" dialog, the internal laptop screen is listed as "unknown", with the only available resolution "3840x2160", frequency "88 Hz". No other options. I also tried xrandr, its output is the same:

My location service setting is on, and I can get my correct location on Google Maps.

But when I turn on auto timezone, it will set the timezone from PST to MST, and I am not even near any MST region.

I tried to turn it off and set it to PST manually then turn it back on, but it still set the timezone to MST.

Can I dualboot Ubuntu and MacOS by using Bootcamp?
aq flag

I was wondering, can I dual boot Ubuntu and MacOS using Bootcamp? Like can I, once I download Windows 10, replace it with Ubuntu? Because Bootcamp creates a partition on the MacOS disk to install Windows 10, right? So is it possible to replace Windows 10 with Ubuntu on that partition?

Do I need to clone an Ubuntu system drive to make a bootable copy?

I like to make bootable copies of my system drives so that when the drive eventually fails, I can replace it and be running again in minutes. With Windows it is necessary to clone the system drive because a copy will not boot. A copy is of course a defragmented alphabetical copy, while a clone puts all the data in exactly the same sectors as they were in on the original drive. Of course, if the system d ...

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.
