Ubuntu full install to USB won't boot updated kernels

I did a full install of the latest Ubuntu desktop to a USB stick using the instructions at How to Create a Full Install of Ubuntu 20.04 to USB Device Step by Step and it boots fine

cn flag

I am very new to linux, so bear with me here. I recently installed Ubuntu 21.04 onto my Dell G5 5090 computer. The installation runs perfectly fine. However, after trying to switch to the NVIDIA proprietary drivers (specifically version 460) and rebooting, the installation gets frozen on the Dell logo. I have tried going into tty, using crtl+alt+f1-12, and using the nomodeset fix, but none of them work. ...

Newly installed Ubuntu doesn't recognize second monitor
mw flag

I just installed Ubuntu 20.04.02 today, everything worked fine expect for the fact that it doesn't seem to be recognizing my second monitor at all. It seems to be a very common problem with Nvidia GPU's but I still haven't found a working solution.

I already tried: installing lightdm, blacklist nouveau, and also downgrading to an old stable version (I tried 390).

Are there any solutions to this prob ...

apt-mark hold only holds one package. where can I check to make sure packages don't install
in flag

so sudo apt-mark hold seems to only hold the last packages.

sudo apt-mark hold shim
sudo apt-mark hold shim-signed
sudo apt-mark showhold

showhold shows just

if I do

sudo apt-mark hold shim-signed
sudo apt-mark hold shim

I thought maybe it was dependency combining as shim and shim-signed are related. so I tested it with a unrelated p ...

Display manager not starting
kr flag

Recently I faced a problem of not being able to control brightness on my laptop so I made a file in /usr/share/X11/xorg.conf called 80-nvidia.conf and pasted something I found online which is clearly not working because when I log in to ubuntu nothing appears, screen is black.

I need to delete that file but I can only access grub when booting by pressing e, so how do I delete it?

I have a laptop monitor with a max resolution of 1366x768. I was wondering if it's possible to make it look like as if it was 1600x900 so that more things can fit in the screen. I have tried the following command:

xrandr --output XWAYLAND0 --mode 1366x768 --scale 1.171x1.171875 --panning 1600x900

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.
