20.04 on XPS13: Chrome hangs, Firefox OK; Evolution loses authentication, Thunderbird OK
mm flag

I have just installed Ubuntu 20.04 on an old XPS 13 9343. The installation was a little painful: using Rufus to put the ISO on a USB stick (as suggested in the Ubuntu tutorials) led to no Wi-Fi. I fixed that by swapping to Universal USB Installer.

I now have Wi-Fi. The thing that is confusing me is that some apps work, while other very similar apps do not. For example, Chrome works when I install ...

Multiple outputs for "apt-cache policy "
cn flag

From what I understand, apt-cache policy <package name> displays the pinning order and thus the releases of package name available in the apt repositories along with their priority orders.

So, if for an uninstalled package, the output consists of various versions (with same priority of 500) which one will be the one to be installed?

For example, $ apt-cache policy git yields me:

 Installed: (none)

I tried changing my mtu from 1500 to 1492 but it didn't solve it.

I'm using a wireless usb adapter.

I have a 27" x 2K monitor so plenty of viewing area. Is there some way I can lock the workspace panel in the out position?

Currently I have to

Tap the "Super"
Move the mouse to the right edge, about a 15"-travel, to pop it out.
Click the **twice** on workspace I want.

I know I can use the keyboard to move up/down, but sometimes I don't know which workspace I want to swap to.

Keyboard and mouse not working after upgrading nvidia drivers on Ubuntu 20.04

After installing the latest nvidia drivers on ubuntu 20.04 I can no longer use mouse/keyboard. I used this recipe: How can I install Nvidia drivers on Ubuntu 18.04 with secure boot?.

I believe this must be something to do with secure boot since I was asked to set a password at the bios screen after rebooting.

Since I can still access via ssh, I have followed the instructions here.

Can't Uninstall A Program (Openshot)

Ubuntu 20.04.3 LTS. Have checked other answers here and nothing is relevant. After I updated Openshot I had two different versions installed at the same time. I deleted one successfully but now the other won't uninstall. I assume some dependencies were taken out?

How do I re-enable my displays?

I have three monitors attached to my GPU. They were all working perfectly fine. Then I went to Settings/Displays and disabled two of them since I just wanted to watch a movie and wanted to try that instead of just turning them off.

Now they have completely disappeared from my settings (although the remaining one is still numbered 2) and I cannot re-enable them!

They are not disabled in the BIOS and, ...

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.
