I am using two DisplayPort and one HDMI on the dock, all terminating into HDMI on the monitors. I can get one additional monitor to work if I use the HDMI port on the laptop.

I was using the NVIDIA 530 drivers before but for some reason, 23.04 does not have  ...

I use Ubuntu 22.04 with Gnome.

This problem first surfaced yesterday morning. I thought (for no logical reason) that some font zip files I'd downloaded the day before might be the problem so i changed permission to 000 for them and rebooted. Then the resolution was alright!

But, when i turned the desktop on this morning, it is again zoomed in!

How can I change desktop/system font size in Ubuntu using commands?

This is really silly but a computer from my classroom has got its font changed to a huge (ridiculous) one. The icons are insanely big and there's no way to navigate through any program, not even system preferences. The only window that is still normaly-sized is the konsole. So I'm wondering: is there a command to edit system font size or a command to change back these settings?

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.
