No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Often with a Linux kernel update, or even after a first install of Linux in place of Windows, Bluetooth stops working and the advice is usually to just power off your computer, wait a bit, and then turn it on again. Bluetooth then miraculously works again.

I mean the issue could also come from other things (not starting the right kernel module etc...), but very often it's just this simple trick that makes it work again.

So what is changing in the Bluetooth device when you do this power off/wait a bit/power on trick?

You're just trying to get the device into a known good state.

The truth is that it's rarely worth trying to find the root cause of an issue unless it's a frequent problem.

Something somewhere went wrong. We don't know if it's a hardware or software issue, so we'll try a solution that covers both.

Powering the device off stops the flow of electricity, and waiting a few seconds makes sure that any capacitors (think of very tiny, very fast batteries) bleed off the power they've stored. Then turning it back on makes it go through the full startup process which is likely to result in a working state.

As a non-technical person, someone on Reddit once explained in a way that makes sense to me as an analogy. Say you are on vacation for a week. Over the course of the week you get pretty good at going from point A to point B, and can even take small side trips along the way. But one day you get a little turned around, and you find you can’t get back to where you need to go. But if someone could pick you up and return you to your starting point, you could do just fine going about your business.

What the asteroid said is 100% true.

I just like to add that when you change system drivers you're adding a lot of unknown state into the equation, which you don't have on day-to-day operation. So it's even less worthwhile to debug what happened. You're not likely to update drivers everyday.
