how to enable headless operation on an Ubuntu 22.04 desktop running on a Raspberry PI without screen
cn flag

I've tried to follow:

RPI4 and Ubuntu 20.04 LTS: Switch between headless and hdmi mode without any changes

but it doesn't seem to work. The RPi fails to boot.

My goal is to be able to connect via Anydesk or something equivalent and get access to a desktop environment even though no screen are attached.

Any ideas?

Too many simultaneous gnome-x-xx and core loop devices?

I have many simultaneous gnome-x-xx and core loop devices.

  1. Why is that? Is each of them required by any currently installed snap app? What produces the installation of each of those snaps? As per "Types of snap" here, core snaps seem to be of type base, and gnome snaps seem to be of type app.

Is there a way to flag a partition in a disk (internal, for the case in point, although I doubt this is relevant) to be read-only? I mean to do it from within Ubuntu (that's why I posted here). I imagine that if this is possible/not possible, it would be the same case from Windows

How to remove Windows efi entry from Grub after drive migration

I installed Windows on a new SSD and then migrated the SSD containing Ubuntu installation, to the one which had Windows previously installed on it.

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.
