Alt-Tab and Workspace Switcher shortcuts aren't working on Xubuntu 21.10

I have switched from Ubuntu Desktop to Xubuntu desktop because Ubuntu no longer supports desktop icons. Unfortunately, in the move I seem to have lost the ability to cycle windows with Alt+Tab and the ability to change workspaces with Ctrl+Alt + cursor keys.

I've tried:

Ubuntu 21.10 installer gets stuck at the Updates and other software screen
fr flag

was going to install Ubuntu 21.10 to dual boot with Windows 11 on an MSI Z590 with an Intel core i7, 32GB of RAM, Secure Boot and tpm 2.0, but the installer does not go to disk partitioning. It stays frozen at the Updates and other software screen for more than 10 hours, and it never moves forward. I already tried the previous version 20.04, and that goes to disk partitioning in just 30 seconds even wit ...

WiFi randomly? disconnects until reboot on Ubuntu 20.04
mx flag

Recently I have come across a bug where my WiFi disconnects, and I am unable to find a network until I reboot my computer. I run Lubuntu only and didn't start having this issue for several months of use. I have not had the opportunity to test if this same issue exists over a wired connection.

The only temporary fix I have found to this problem is to reboot my computer, but even then, it only star ...

Browerpass in snap Firefox
cn flag

I just migrated from 21.04 to 21.10, and as a result, I'm now defaulting to Firefox snap package.

It seems this breaks Browerpass plugin, with this error:

Error: Error: Attempt to postMessage on disconnected port

It also seems to break Gnome extensions management from Firefox.

So, what are the possibilities/limits of Firefox snap package regarding plugins, especially those that rely on Native Mess ...

How to remote into xfce + i3?
cn flag

I followed this guide to make an xfce set up with i3 as the window manager. On the log in screen, I have to select Xubuntu (out of i3, XFCE, and Xubuntu) to log in. I've tried changing ~/.xsession to startxfce4, xubuntu-session, i3-session, but they either don't work or drop me into regular XFCE.

How do I tell xrdp that I want to remote into XFCE + i3wm instead of just XFCE?

Skip Authenticating OBS Virtual Camera
us flag

I just installed OBS 27.1.3, and, having used OBS 25.x.x, I was surprised to see that they added a Start Virtual Camera button. This is very useful, but mildly annoying when I want a virtual camera in a hurry, because I have to enter my password every time I want to start it.

Is there a way to skip the authentication step, perhaps by allowing v4l2loopback to run without sudo perms? I am the only one  ...

Login Greeter takes 20~30 sec (after bootup apparently finished) to appear

I looked into this question among a few others (on and off SO) for a solution.

The upvoted (but not accepted) answer to that question, suggests entropy might be a problem. I have infact from the beginning both haveng and rng-tools installed and enabled, and the entropy is pretty high (as per the comments on that answer, which suggest something close to 4000 as a good value).

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.
