Stuck on GNU GRUB 2.04 UBUNTU 18.04.6
ru flag

My dell laptop only has ubuntu installed, I bought it already installed no dual boot whatsoever (most solutions I have found are for people with dual boot). Occasionally I would get stuck on GNU GRUB for a few hours after turning on my laptop. At first I thought that what caused it is turning off the laptop with earphones plugged in but lately this has been happening even if I unplug them before turnin ...

dual monitors sometimes fail
cn flag

I have 2 monitors attached to a GP108 GeForce GT 1030.

  1. an AOC32'', 2560x1440 on a dvi port
  2. an 52'' Chiq 4K tv, 3840x2160 on hdmi

I'm normally using nvidia proprietary drivers, 495.46.

Sometimes, my tv stops working (no signal). Typically, it comes back after unplugging and replugging the hdmi cable twice. Today, it didn't.

After booting, on the login screen, both screens are typically working.  ...

Second monitor not detected after reboot

I have been using Ubuntu for a couple of months and am still pretty new to the whole thing. My computer has stopped detecting my second monitor (I make dual boot and on windows, it detects the monitor fine). I have tried uninstalling all my AMDGPU drivers and reinstalling it trying to fix it.

I ran $ sudo lshw -c video and this was the output

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.
