Swap out one distro in a dual boot setting for another, without affecting the second OS?
cn flag

I have Lubuntu installed, alongside windows being dual booted. I was trying it out as my main distro and it sucks. I'd like to keep the windows install, but replace the Lubuntu install with Xubuntu.

Someone suggested that I manually partition it, but I don't know how to do this. They also suggested that arch might be easier since everything is manual, even installing the bootloader. I'd need help  ...

I recently switched from using the HDMI ports on my monitors to using DisplayPort (for high fps gaming). On Ubuntu I've run into a really annoying problem: very often, when I leave my computer for a while and the screens go black, it becomes very hard to wake the monitors by shaking the mouse or pressing keyboard buttons. When the monitors finally wake up, the resolution on the computer is completely me ...

What is Unknown Process Called "hp-upgrade"
vn flag

I use a home-brew desktop PC that runs Xubuntu 18.04 (fully updated). Attached to it is an ancient HP Office Jet G85 printer. In my last 2-3 sessions there has been a process called hp-upgrade that takes 88% of memory (according to top) and seems to begin at start up. It keeps on running for hours until killed. Anyone have an idea or experience with this? Thanks, Howard

Now, when I click network tray icon, "Wired Connection 1" has been replaced by "Auto Ethernet" as you can see here.

If I click on "Auto Ethernet", then the connection works as expected, but I now get regular disconnections, like after 5-10 minutes.  ...

I just installed an Ubuntu 20.04 on a VM managed by VirtualBox. I set-up a password, but I couldn't login with it after the installation, "wrong password".

My wifi disconnects automatically at certain intervals. Shows a question mark symbol over the wifi when it happens. After I restart my router the wifi works fine. But I don't know what is the issue with my laptop. I have Windows and Ubuntu installed. Is there a way to check the system configurations and check the issue? I'm new to Ubuntu.

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.
