Ubuntu will not load with kernel 5.11.0-25-generic
in flag

Ubuntu updated to kernel 5.11.0-25-generic and will no longer load. It goes through the non graphic stuff and eventually goes to a flashing _ . That _ eventually disappears and vertical green lines flash on my screen.

If I tell GRUB to load kernel 5.8.0-63-generic-boot, Ubuntu 20.04.2 loads correctly. I am fairly new with Linux so please be patient with me.

Ubuntu animations are very slow and videos run on low fps
sh flag

I have recently downloaded Ubuntu for the first time using dual boot alongside windows 10. But animations for opening, minimizing and snapping apps are VERY slow and laggy, and the animation when you open "Show Applications" is really slow and bugs most of the time.

Video playback is also really slow when using VLC or Totem (videos run at like 7 fps)

Windows runs fine and fast on my hardware. But Ubu ...

I'm kind of a Linux noob and have been for almost 15 years, but I am trying to keep it active and learn more.

How can I fix IO lagging after installation of RAID controller card?

Several months ago I have installed a hardware RAID controller card in my workstation. Since then I frequently experience annoying lags of my keyboard, something keystrokes are missing and something they are in wrong order (as if they were delivered by threads running in parallel). I have also noticed that my mouse and GUI misbehaves (Firefox, PyCharm) and that it sometimes takes a noticeable time (seve ...

System Freezes when a new bluetooth device or USB device is connected for 5 seconds
cn flag

I'm using Ubuntu 20.04 with kernel 5.11.0-25. If I connect a Bluetooth device (e.g. my keyboard after going to sleep or a new USB device, but not SD cards) the system will freeze for around 5 seconds. Audio will keep playing, but the image is frozen and the mouse/etc will not work.

Unfortunately I cannot show any code or ideas.

How can I solve this problem?

Can we get debug packages in Launchpad?

I see some project offering their ...-dbgsym.deb packages on launchpad (see ALSA).

My projects, however, do not seem to generate those packages.

When I create packages on my machine, I do see those packages.

Could it be that it is turned off in my project?

Could there be an issue where the compiled version is pure release and thus the libraries anyway do not include any symbols and as a result not dbgs ...

Basically I have a Microsoft Designer Mouse that works on my personal laptop (dual boot) on W10 and another laptop on Arch but I can't find it in any way using Ubuntu 20.04.2 LTS.

Is there anything I could try to make it show up and pair?

Thanks in advance guys

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.
