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 :))

Hello and welcome to this new community for talking about Kakoune !

I am by no means an expert on kakoune, but I love using it. I created this community, exactly because I am not an expert, and I wanted some place to learn more and talk to other people who like kakoune :))

If you want to ask a question about kakoune, share your kakrc, your favourite plugins or your workflow using kakoune - please do so here :))

If you're not (yet 😉) using kakoune, you're also welcome to participate and ask questions :))

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.

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 ? :))
