Shift Keys don't work in Ubuntu Studio
se flag

Both Shift Keys (L and R) don't work in Ubuntu Studio and xev command cannot detect them when pressing the keys.

They weren't working on Windows 7 either, the OS I was using before installing Ubuntu on my old laptop a few days ago.

However, when I pressed shift to get into GRUB menu on start up, the left Shift key did work and got me in GRUB.

Any advice on what could be the problem?

Tools to interpret MCE error on Ubuntu 18.04

I have an unstable system (reboots at random) and am trying to determine the cause of the reboots. My question is whether these MCE are serious errors that could be leading to the reboots. If so, should they lead me to replace my CPU or RAM?

After every reboot (whether random, or initiated by sudo reboot) the following MCE are produced:

how do I delete a volume from zpool - zfs

I created a zpool with 12 drives each 8TB using:

zpool create ch1 sdb sdc sdd sde sdf sdg sdh sdi sdj sdk sdl sdm

Then I added 12 more 8TB drives and wanted to add them to the zpool. When I did I only got 8TB of additional space instead of the expected additional ~70TB using this command:

zpool add ch1 raidz sdn1 sdo1 sdp1 sdq1 sdr1 sds1 sdt1 sdu1 sdv1 sdw1 sdx1 sdy1

I want to display the top "panel" bar on all monitors, instead of just one in Ubuntu 20.04 with Unity desktop.

I have seen suggestions in other threads to install an extension for Gnome desktop, but I am looking for a solution that works on Unity.

Any suggestions for Ubuntu 20.04 with Unity.

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.
