Dual monitors on login are working in a mirrored mode instead of be handled as extension
cn flag

I have a laptop and recently connected second monitor (VGA). The problem is when I first boot both monitors show same login screen (like in the mirroring mode).

After login in, both monitors are working as expected (the one is an extension of another). If I lock the screen the login screen appears only on one display.

I am using xfce and lightdm.

I guess the problem is with the boot order of some parts ...

The problem exists running off the live USB or clean install with 20.04.2 and 20.04.3.

Have had to clean install 20.04.1 and not allow updates.

This is causing very short battery life.

Have filed bug report but could not understand the further info  ...

Frequent Hard Lockups
jp flag

I have suddenly (in the past couple of days) begun experiencing hard lockups on my laptop. When this happens, neither the mouse, keyboard, or display respond. This seems to always happen when I am typing - the keystrokes I type don't appear on the screen until I move the mouse, then it rapidly catches up. Every dozen or so times this happens, the mouse won't move and the characters won't appear and I ha ...

Xfce - is there any way to speed up "close window" for unresponsive applications?
us flag

In Xubuntu 20.04, if a window won't close first time, it brings up a dialogue with words to the effect of "This application is taking a long time to close, do you want to kill the process?"

What is it actually doing? Is it something like sending 5 close requests with a 5s interval between them and if the process is still running it then offers the user to send a kill request?

Can the number of attem ...

remmina no longer working after Ubuntu update to 20.04 "cannot connect to RDP server localhost"
ng flag

Until sometime last night, I had remmina working fine. Then it stopped working. I can get as far as the password dialog for my work machine, but then it just says Cannot connect to RDP server localhost.

I can't even find any logs that look interesting. I've re-installed remmina, cleared my .remmina directory, restarted my machine, and even restarted my gateway.

Any thoughts?

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.
