How to stick to stock Ubuntu 20.4 LTS without the automatic kernel update during installation? Any boot parameter?

Is there any kernel/boot parameter I can pass by entering grub pressing the E button? As I start the install process for Ubuntu and it gives me two options which say try ubuntu and install Ubuntu. I do not want any option such as this. I want to bypass the try/install Ubuntu step and ...

Install Adobe Acrobat XI with wine is not a duplicate, since it does not address the issues I am having.

I am running dual boot with Windows 10 and Ubuntu 20.04 and I want to install Adobe Acrobat Pro to run using wine. I have it installed on Windows. I created a clean wine prefix using WINEARCH=win32, all wine related commands are run using this configuration (via aliases in my .bashrc). I then ran ...

remove graphics card from ubuntu server machine
cn flag

I used a old HP media PC to install Ubuntu Linux 20.04.3 and removed the video card and restart the machine. The server boots after making several beeps. I guess it is because I removed the graphics card. Is there any way to remove this GPU check during bootup?

netem how to do delay for 2-3seconds of all packets for 50-300ms once in 3-10 minutes
pk flag

I'm using netem to do traffic delays. For my testing it is required to perform slightly odd delays. I need introduce a delay 50-300ms to all packets TCP/UDP for 2-3 seconds once in 3-10 minutes. I.e. once delay has happened next delay should happen in 3-10 minutes.

Can I do that just using netem without using additional scripts?

If not, what's the closest achievable?

boot error malformed security header

I'm running Ubuntu 18, at startup I was given this warning followed by a dark blue screen, almost black. Nothing else happens, I've tried restarting a dozen times, each time the same.

Malformed security header Failed to read header: Invalid Parameter Failed to load image: Invalid parameter Start_image() returned invalid parameter

Anything can be done besides a clean install?

Screenshot open select element crashes mouse interaction with ubuntu's UI
ec flag

How to replicate:

  1. Open a select element on a website
  2. Try to take a screenshot using Ctrl + Shift + PrtSc
  3. Try to use your mouse to do anything else except for the browser window

You cannot switch applications using your mouse. You cannot do anything with your mouse except in that browser process.

I am 90% certain that this is the same case with all browsers.

The only fix I found was rebooting th ...

Xubuntu 20.04 - why is the desktop area freezing?

This is Xfce added onto Ubuntu Studio 20.04.

The graphics card is GeForce GTX970 and the proprietary legacy driver v390. Which is pretty stable and has been working for years.

There are two monitors side-by-side. The problem affects both desktop areas.

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.
