Problem with wifi, after seconds lose internet
us flag

I have problems with some networks in Ubuntu 18.04 When I connect to the network, everything is fine. A few seconds later (5/10 seconds) it stops working, from the browser I get DNS_PROBE_FINISHED_NO_INTERNET

If I execute ping 8.8.8.8 I get a similar result, the first few seconds works fine and then I stop getting a response.

At first, NVidia drivers were the problem, but they were successfully installed. Now, I can't even boot to Ubuntu.

Epson ET-2750 upgrade?
fr flag
dms

When I upgrade from Ubuntu 18.04LTS to Ubuntu 20.04LTS will my Epson ET-2750 printer setup from 18.04 upgrade to 20.04?

I could not install the Epson printer on 20.04 standalone. The only difficulty I could see was 20.04 would not accept USB as a connection; 18.04 did accept a USB connection.

How do I make 1920x1080 screen resolution permanent? Lubuntu 20.04 Virtualbox Windows host
es flag

I found this:

xrandr --newmode "1920x1080"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode Virtual1 1920x1080
xrandr --output Virtual1 --mode 1920x1080

Gets me the resolution I want until I start Linux back up and it returns to 600x800.

How do I make Lubuntu keep these settings after restarting?

Nvidia Prime enable vsync

A few days ago I posted a similar issue where I was stuck on booting screen before login after doing some manipulation on nvidia drivers.

The reason I did this was to enable vsync in order to get rid of permanent screen tearing issues. I could find many references to similar issues on the web and most of them rely on either enabling the issue from Nvidia X Server Settings (which I can't do) or editing ...

Ubuntu 20.04 not recognising a new optical drive

I am completely fed up with the noise and repeated glitches on my old built-in optical drive so I bought a Froibetz pop-up mobile external dvd-rw reader.

This connects via USB3 or Channel C and claims to be Linux Chrome compatible (isn't that Linux?) When I connect up both via USB 3.0 and C - it is now at least being recognised but when I go to play a track on Audacious it stalls at first track.  ...

Where are fonts determined besides System Settings and my browser?

I'm running Kubuntu 20.04. Two places where the font sizes used in an application are determined are the Fonts section of Appearance within System Settings and the browser I'm using (plus the application itself in some cases). When I'm having font problems,where else should I look? (This question is a generalization of one I asked yesterday about Audacity.)

Looking at it another way, how does A ...

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.
