UBUNTU 21.10 Raspberry Pi Displays freeze when second monitor is connected
cn flag

I updated my RPI4 system to 21.10, the display system freezes when two monitors are connected. When I disconnect either monitor (Dell 27 4k and ViewSonic 20 fullhd) everything works fine. I have swapped the ports for the monitors with no change. I also added 'linux-modules-extra-raspi', which helped get microk8s working on my headless systems, but no change.

When this occurs the clock at the top  ...

Is it possible to downgrade the Kernel version of Ubuntu 21.04 for Raspberry pi 4?
cn flag

I'm working on Raspberry pi 4 under Ubuntu 21.04 with Arducam Stereo Camera.

I can't install the camera driver because the driver does not support the kernel version of Ubuntu 21.04 (5.11.0-1007-raspi)

The camera driver supports only those versions:

4.19.113-v7+
4.19.118
4.19.118-v7+
4.19.118-v7l+
5.4.42-v7+
5.4.51+
5.4.51-v7+
5.4.51-v7l+

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.
