sytstem won't wake up when opening lid
eg flag

I have this problem. I can put my system to sleep, close the lid and it will have no problem waking up. But if I just close the lid it will not wake up after reopening the lid. The powerbutton lights up, but otherwise it won't react to anything. I have to do a hard shutdown by holding the powerbutton. After starting the system up I have no errors. Anybody knows how to change this behavior.

My question is how can I make it so that when I type reboot/shutdown/halt, ubuntu always asks for the sudo password even if there is only one user currently logge ...

HP laptop not resuming properly from sleep
cn flag

On Kubuntu, resuming the laptop from sleep leaves me with a blank screen and the mouse only. The mouse moves normally which indicates that the touchpad is working. It once showed errors that the EXT4 partition is read only or something like that but I couldn't get it to show again. I suspect that the SSD is not resuming from sleep.

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.
