Dell Precision 7730 OEM Ubuntu

I'm struggling with installing Ubuntu. The only way I could run Ubuntu was with nomodeset but nothing worked graphically.

Before that I had made a very successful install with RAID config on, but due to a lot of crap I needed to install both Windows 10 and Ubuntu. I turned off RAID (also better in Windows 10) and the Ubuntu installer wasn't even loading. I had a lot of problems, and I couldn't start an  ...

Using Ubuntu desktop as server (Pi-Hole), what if user enters suspend mode?
mx flag

I have setup a machine for guests and for home use when we need a quick web browsing. This machine is infrequently used. Most of the time it is on suspend mode (consuming 2 watts).

I would like to run Pi-Hole on this machine. But this would requires the machine to be permanently on (Ryzen 5700G, integrated graphics, watt meter shows 30W when computer is idle, not suspended). Maybe I just need to apply

Unable to connect to the internet when using X11

I have a machine that is running Ubuntu server 22.04. When running the X server no applications can connect to the internet.

Display DPI changing when wakeup from sleep

How do you keep an application in the dock in Ubuntu 22.04?
cn flag

When I open an application it appears in the lower part of the dock, but it disappears when I quit it and it would be useful if it could stay there.

MacOS and Windows have had this feature for years; does Ubuntu not? It certainly doesn't seem to -- only what's in there by default.

When I right click a running application there is no option to keep it there -- only all windows and quit.

For example, when I try to rename grandpa's_pen.mp4 to grandpas_pen.mp4, the action takes too much time.

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.
