Any good calendar app in Xubuntu?
fi flag

I'm trying to find a calendar app that works with the Xfce desktop. I do not want to use a gnome-based calendar, as I do not want to have the heavy gnome programs to run in the background, as my ram is very limited. I also want it to be synchronised with google calendar, which I use on my phone.

All that google proposes me is that old "orage" calendar app for Xfce from 2010.

Any help ? Shall I give up ? ...

Cups Server change printers.conf location

Some background:

I have ubuntu 20.04 LTS installed on a Raspberry Pi 4 Model B, on this I am running CUPS (v2.2.10) in a docker container as a print server.

CUPS itself is running fine, I have installed printer drivers and configured a local printer using the web interface.

Missing first character when mouse-selecting text
ma flag

I'm using a pretty standard Ubuntu 18.04 setup, with Gnome Desktop, and I'm having difficulties to reliably select text with the mouse (sic).

I move the mouse cursor above the first character to be selected, press left button, drag the mouse until the end of the text, and release (like everyone else I guess). I expect the first character under the mouse cursor (where I start selection) to be part ...

Scaling monitors
in flag

I have two monitors, one on my laptop that have the resolution 3840x2160 and one external that's 1920x1080. To be able to see anything on my laptop I need to have it at 200% scale but then everything get to big on my external screen. I have tried xrandr --output DVI-I-1-1 --scale 0.5x0.5 to try and scale the second monitor. This make it so the second screen is only a square at the top right instead.

How to Setup Canon MG5370 printer-scanner in Ubuntu 20.04?
cn flag

Canon MG5370 printer&scanner is connected to the same network as Ubuntu 20.04. Using Settings --> Printers --> Add, Ubuntu 20.04 is able to detect this printer. However, when I try to "Test Print", nothing happens.

I believe this happens because it is using a generic printer driver. See picture below.

Cannot access dir although user belongs in the group
cn flag

I have a directory named foo that has the following permissions:

ls -dl foo
d---r-x---  3 foobar  staff  96 Sep  1 10:29 foo

While executing groups or id when logged in as foobar I get back a list of groups that contain staff and gid=20(staff) groups=20(staff) respectively. My understanding is that this means I'm a member of the staff group.

However when trying to do ls foo/ I get back Permission denied

What's the official support period for Ubuntu Core releases?

There recently was talks on Meta about the support period of LTS and non-LTS releases on this site. In addition, I saw the mention of Ubuntu Core in a comment, and this got me wondering what the support period for Ubuntu Core actually is, and if it follows the support period for Ubuntu LTS.

Canonical states this on the Ubuntu Core page:

Snap points me to a package that, in fact, doesn't exist. What's going on?

So, I just did the following and it makes absolutely no sense to me. (Please ignore my custom $PS1).

Let's try to install Vs Code in a wrong way (the correct package name is code), and follow through snapd's suggestions:

Internal Microphone Not working but when connecting with earphones internal and external mics are working, and giving options for both

I am facing an issue with my internal MIC for the last 1 week. I updated my UBUNTU 18.04 and my sound stopped working. I tried update commands but none worked. Later by installing Pulseaudio and Alsa MIxer my Sound came back. But instead of showing Built-In Sound, it was giving Snd-hda sound option. I tried almost all options from the various platforms but none are working.

This command works perfectly fine if I enter it at a terminal prompt in Ubuntu 20.04:

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.
