New Dell 7090 Tower - Installed Ubuntu 20.10, 21.04 and 21.10 - Getting network packet loss until usb thumb drive plugged in
ng flag

I recently got a new Dell Optiplex 7090 Machine, i9- 10900, 64GB Ram

I attempted to install Ubuntu 20.04 (Server, not using GUI so only using the server version) on it but after the first screen where you select install Ubuntu the display goes blank/loses signal. I assume the hardware is too new for 20.04.

I installed 20.10 (or maybe it was 21.04) and it installed fine, no issues, smooth as expected ...

Bluetooth headphones don't switch when switching users
ru flag

If I switch users, as opposed to logging out as one user and logging in as another, my bluetooth headphones stay attached to the "old" user. That is, whatever the old user had playing is still playing when I've switched to the "new" user.

If I go to bluetooth settings and disconnect and reconnect the headphones, I can connect them to the new user, but only in headset profile and not A2DP sound pr ...

Main display randomly turns black and turns back on after some seconds
mx flag

I am using Ubuntu 20.04.2 LTS. Nearly 2 times a day, my main screen randomly turns off (it seems like it is not recognized for a short period of time) and all my open windows will be moved to the second monitor. After 10-60,seconds the main-monitor turns on again, and I can continue to use the OS normally. In the following I have attached the syslog, which was output when the event was happening.

Set the same mouse sensitivity on Ubuntu and Windows
cn flag

I am having trouble setting same mouse sensitivity on ubuntu and windows.

I am not interested in a trivial solution like using a ruler, I want to be sure that the sensitivity is exactly the same by disabling the "operating system sensitivity".

As an example, I would like that if I connect a mouse with 800 DPI on an Ubuntu and a Windows machine, the mouse has the exact same speed.

Ubuntu using llvmpipe (LLVM 11.0.0, 256 bits) as graphics

I just installed ubuntu on my computer and I'm having a lot of trouble getting the graphics to work. Only one display is detected, and it is shown as unknown and I'm not able to change resolution.

When I go to the about page in settings, the graphics are shown as llvmpipe (LLVM 11.0.0, 256 bits), which I'm pretty sure is wrong as I have an rx 6800. I've been using windows my entire life, but fina ...

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.
