How to turn off Gnome's keyboard-touchpad auto disabling on "2 in 1" laptop?
cn flag

I have a Lenovo IdeaPad Flex 5 laptop, a so called "2 in 1" model where you can turn the screen around and use the machine in tablet mode. Gnome can detect turning the screen and disables the keyboard & touchpad when it believes the machine is in tablet mode. The problem is that it is often wrong about its believes and disables the keyboard when I want to use it.

This was mildly inconvenient  ...

I ran sudo chmod 764 /usr and then my laptop rebooted, now I can't open Ubuntu login screen anymore. Help me please.

Edit:

Bluetooth headset microphone not working after reconnect
ng flag

I have a Bluetooth headset (HS70 BT) and I have this annoying issue where the microphone doesn't work when I reconnect it.

That is confusing so I'll recap :

  • When I first paired it with my laptop, everything worked as expected.
  • I then disconnected the headset (to plug it elsewhere or just shut it down to save battery)
  • When I reconnect it, the microphone doesn't work, I can see the device listed 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.
