I searched everywhere to find a solution and the only one i found that makes a difference is to enable IOMMU at bios settings. But then all of a sudden my usb 3.0 ports are the ones that get disabled. Any solu ...

20.04 freezes after waking up from suspend
ye flag

I think my problem is very similar to one already asked:

  1. 20.04 crashes on suspend after upgrade from 18.04
  2. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1882917 - I've also tired all the things this user has tried doing.
  3. https://github.com/pop-os/pop/issues/1172 - something very similar happens on POP OS.

I think is something deeper and has to do with kernel. I am on AMD Ryzen 7 and this behaviou ...

Diagnosing a Bluetooth headset HSP/HFP issue with PipeWire - Ubuntu 20.04
na flag

No, this is not another "I have Ubuntu 20.04 and my bluetooth microphone doesn't work" question.

I did some research and found out about Pulseaudio and oFono problems.  I've tried many things, including kernel 5.12.12 installation - nothing has helped.  I gave up for a moment, digging out the old wired headset from the garage. Then I installed Fedora 34 on my second computer and, to my surpr ...

What's the difference between the -d and -m options for useradd?
jp flag

When we use useradd, what is the difference between -d and -m? Because the definitions of both sound similar, which is responsible for creating a home directory.

How to delete this WindowsApps folder (permission denied with rm even with sudo :( )?
cm flag

I used to use windows on my laptop and then moved ubuntu. While I was using windows, I once moved microsoft store apps to a different partition to save space in C drive and I guess it was saved in "WindowsApps" folder. Now I use Ubuntu and I don't need that folder anymore but can't delete it. If I execute sudo rm -rf ./WindowsApps then I get

Remove a specific snap package
ar flag

When I run df -h I see that I have several /snap entries with similar names and sizes. I've edited and rearranged the output, so that similar names all appear together (see below).

I am guessing that I should be able to remove (for example) the earlier instance of Gimp: /snap/gimp/367. This article tells me how to reduce a named snap package, but I haven't found how to remove just one of two packages w ...

Log process for outgoing connections
cn flag

Is there an easy way to set up logging of all outgoing connections to certain ports, for example? Trying to figure out which programs/processes causes certain outbound connections.

Server is already using UFW, and logging these connections, but there is no indication of "who" is causing them.

lsof and ss does not seem to be able to listen continuously like this?

When you click on "power off", you only get three options: cancel, power off and restart.

I was wondering if you can change it so there are more options like "suspend" or "log out" Like seen here

No space left on device before upgrade to Ubuntu 20:04 LT

I've been running Ubuntu 16.04 and recently have been getting regular messages that there is "no space left on device". I'm concerned that this will cause problems if I try to update to Ubuntu 20.04 LTS, so I would like to fix this first.

I have followed all the recommendations I have found in other threads, but the problem persists. Here is the output of df -h:

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.
