//Solution:

I installed this driver (https://github.com/morrownr/8821au-20210708).

The driver however, did not work until I ran a script called remove-driver.sh from the driver that I used to use (https://github.com/morrownr/8821cu-20210916). Then the wifi adapter started working again :)

Thanks a lot for the help - I am still not really sure what the problem actually was, but I'm very thankful for having my internet connection back :)

Hey :)

I've been using a wifi adapter for my computer for about a year. A few days ago, it suddenly stopped working. It no longer shows up when I run 'nmcli device' in the terminal. When running 'lsusb' it still shows up as 'Realtek Semiconductor Corp. 802.11ac NIC'.

To my knowledge I hadn't updated anything before it stopped working. After it had stopped working, I used usb-tethering from my phone to do a system update, hoping it would fix the problem. I think one of the updates was a linux firmware update. Anyways, it didn't fix anything.

The adapter didn't work out of the box. It arrived with a driver called 'RTL88x2BU' and a document stating that it was compatible with the following chip drivers for linux: RTL8811AU RTL8811CU RTL8812BU RTL8814AU

I couldn't get the driver it arrived with to work, so instead I downloaded this driver and have been using it until it stopped working. https://github.com/morrownr/8821cu-20210916

this driver only states that it supports some linux kernel version. I'm using '6.8.0-40-generic', which it does not claim to suppport. I download this driver, which should support my kernel, but it didn̈́'t work either. https://github.com/morrownr/8821au-20210708

I've tried running lsmod on my system, and it seems to be, that no wifi driver even starts. The only thing I can remember doing just prior to my internet not working, was running 'systemctl disable jellyfin.service'. I doubt that has anything to do with this, but I'm not sure what else it could be. My only other theory is, maybe the usb wifi adapter hardware just gave up.

Any help is appreciated ^^

I've recently bought a used computer, and it has a few problems. I'm looking for a guide to help me identify which parts are causing the problem.

I've tried to watch and read a few guides on how to build a pc, but they haven't given me any information on how to identify broken parts.

I'm interesting in a guide, but I'll also post my specific problems, if any of you know how I might fix them ^^

the problems I'm experiencing are the following:

the screen will sometimes glitch out with black areas when watching movies, but only when in fullscreen. The problem usually disappears for some time when exiting and re-entering fullscreen mode.

The computer won't run certain drivers and sometimes when powering off, the computer will use a long time closing certain applications, but will fail in the end and I have to power it off manually. Also, it will sometimes reset my settings. Back to factory wallpaper and factory everything. it remembers my users and my applications.

I've grouped them into two paragraphs, because I have an idea, that the graphical problem might be caused a bad GPU.

I have no idea, what's causing the stuff in the second paragraph 😅

also, I hope this is the right community for this question - I couldn't find any communities specifically for computers.

any help is welcomed ^^

//EDIT:

Thanks for the help :))

I removed the gpu and now only use the integrated graphics in the cpu, and the visual glitches are gone :))

I've run some tests on the computer (from the boot screen), and it seems the memory is fine. The only driver I know to be a problem is the driver for my WiFi usb. I'll try to work on that, or maybe I'll buy a WiFi card and pray that works better ^^

thanks for the help :))

//EDIT2:

All my problems are fixed now ^^

the wallpaper change was because I am a doofus and forgot that I had made a new user on the computer, which of course had the default wallpaper 😅

the driver problem was only with my WiFi adapter, and I fixed that by removing the current driver (rtl8812ub) and installing another driver (rtl8811au), which fixed the problem :))

thanks for the help :))

I just saw somebody on mastodon share this fact, and I wanted to share it here too :))

It can be explained by the follow:

2025 = 2024 + 1

2025 = 45²

45 = 1 + 2 + ... + 9

(1 + ... + n)² = 1³ + ... + n³

and since 1³ is just one, we get the above equation for 2024 :))

This also means that next year will be even nicer, as it will include the 1³ :))

Do you have any other interesting facts about 2024 ? :))

The best name I've found for the last formula is just "Sum of consecutive cubes". I had never heard about that relation before, it really is bizare how math is connected sometimes :))

hello :))

I hope this post is okay. I just wanted to share, that I've created a new community on lemmy for talking about the modal text-editor Kakoune (inspired by vim).

It is located at [email protected] and you're welcome to join whether you're using kakoune already or just want to learn about it :))

Hey :))

I'm trying to get smooth scrolling to work with Vi bindings in Zathura. It works out of the box with "" and "". I found a solution on the internet saying you could map j and k to "" and "", which I've done by writing the following in zathurarc:

map j feedkeys "<C-Down>"
map k feedkeys "<C-Up>"

And it works :))

the only problem is - every time I press either j or k, it writes the following error to the terminal:

(org.pwmt.zathura:112248): Gdk-WARNING **: 08:53:50.919: Event with type 8 not holding a GdkDevice. It is most likely synthesized outside Gdk/GTK+

Is there a better way to get smooth scrolling with vi bindings in zathura ? ^^

// This post has been a hell with formatting, sorry

hello :))

I have problems with the WiFi adapter on my new pc, and in order to troubleshoot I need to use some utils that are not on already on the computer.

is it possible to just copy the binaries from a computer with internet connection onto a usb drive and move them over that way ?

And in that case, how do I make sure to also copy all the dependencies ?

or is there a smarter way do to it all together ? 😅

I hope this is the right community for this question :)) I couldn't find any community specifically for Linux tech support.

I've played klondike for most of my life, but I've recently started exploring some other variations and I really like them :))

My favourite at the moment is Free Cell :) I'm a major fan of the fact that (almost) every deal is solvable. It is also an open solitaire, meaning that all the cards are face-up from the beginning. This means, that if you lose a game of Free Cell, it is likely because you could have planned better ahead. Sometimes I find this a bit too stressful and I resort to playing other Solitaire games, with more luck involved :p

I do still play klondike from time to time, but after experiencing playing Free Cell, the amount of games that go nowhere can sometimes annoy me. I think it is a nice way to pass time and I like the adaptive nature of the game, having to change strategy depending on which cards are revealed. I also feel very nostalgic about this variation, since it's the one I've been playing most of my childhood.

Pyramid and Aces Up - I really like to play these variations, when I'm very tired and just looking for something easy to play. I have yet to win a game of Aces Up even though I've played over 100 games. I can't figure out, whether I'm using a wrong strategy, or the odds of winning just are that low 😅

I've played a lot of Spider solitaire in the past, but at the moment I prefer Free Cell, when I'm in the mood for a 'complicated' solitaire. Spider is the only solitaire I play, which uses 2 sets of playing cards. Though I mostly play on my phone, I've actually bought a set of Solitaire playing cards, that are very small. The times I've played Spider solitaire with regular playing cards, they've taken up a lot of space. The small cards help a lot with that issue :))

This community is not very active at the moment, but if you stumble across this post, feel very welcome to share your favourite solitaire variations in the discussion :))

Hey, I hope this is the right community for this question :))

I volunteer at a local place, but they only communicate through a facebook group that I never check. My question is -

Is there a way to get a notification, whenever there's a new post in the group, hopefully through some FOSS :))

//Edit: It's a SAS drive. thanks for the help :))

I bought two of these a long time ago, and I recently tried to connect them to a SATA III connector without luck. The size seems to match up, but the block between the two pin segments seems to block it from connecting with SATA III.

Can you help me figure out what kind of adaptor I need ? :))
