The Errors when it succesfully login me via OAuth2 via browser or try to click the retry button

Sending of the message failed.
Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

Login to server smtp-mail.outlook.com with username [my email] failed.

Everything seems to be set up correctly, but for some reason I'm only able to receive emails and not send them through Betterbird, and I find this strange because the same email account works fine on Fairemail (Android), I can send and receive emails there.

I also have a gmail account and it works both ways, this is only happening on outlook, very annoying.

Virt-Manager 3D acceleration + OpenGL fails when trying to start vm with “EGL-Initialize failed: EGL_NOT_INITIALIZED”

I enabled 3D acceleration and OpenGL to improve performance on my Fedora test VM (to test some non-malicious software before fully installing them into my real system), but I got hit by a popup error “EGL-Initialize failed: EGL_NOT_INITIALIZED” and a SELinux alert, that gave me two options semanage fcontext -a -t virt_image_t '/usr/bin/nvidia-modprobe' & restorecon -v '/usr/bin/nvidia-modprobe' or sudo ausearch -c ‘qemu-system-x86’ --raw | audit2allow -M qemu-nvidia & sudo semodule -X 300 -i qemu-nvidia.pp (which option would be the correct one for this?). I tested both separately, but even so, it kept giving the same error:

Selinux Alert:

SELinux is preventing qemu-system-x86 from getattr access on the file /usr/bin/nvidia-modprobe.

*****  Plugin qemu_file_image (98.8 confidence) suggests   *******************

If nvidia-modprobe is a virtualization target
Then you need to change the label on nvidia-modprobe'
Do
# semanage fcontext -a -t virt_image_t '/usr/bin/nvidia-modprobe'
# restorecon -v '/usr/bin/nvidia-modprobe'

*****  Plugin catchall (2.13 confidence) suggests   **************************

If you believe that qemu-system-x86 should be allowed getattr access on the nvidia-modprobe file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'qemu-system-x86' --raw | audit2allow -M my-qemusystemx86
# semodule -X 300 -i my-qemusystemx86.pp

Como eu faço para me livrar do spam da Tim?

Eu tenho um plano de celular da Tim e toda hora eles ficam me mandando SMS sem parar, e se não for SMS, é pelo WhatsApp, ou ate pelas malditas mensagens de broadcast que tomam conta da sua tela e mantém o seu celular com a tela ligada ate você apertar sim ou nao.

É sempre ou spam, bet ou anuncio.

E não adianta bloquear, sempre aparece outro contato aleatório da Tim ou algum número aleatório.

Eu já tenho o filtro de spam ativado e também já criei um modes and routines (Samsung) que fecha imediatamente o aplicativo Sim kit sempre quando ele abre (descobri que as mensagens que sobrepõe a tela vem dele) mas mesmo assim alguns acabam escapando, eu realmente gostaria de minizar muito ou alguma forma de não receber mais esses anúncios da Tim.

(Terceira imagem não é minha mas são esses tipos de anúncios também, esqueci de tirar print na hora, tem dias que aparecem uns 3 e dias que aparecem 5)

I've already checked Opensnitch and my systemd with NextDNS, and neither of them seems to be blocking this operation.

What could be causing this, and how can I find that out? It doesn't seem to be firewalld either, though I haven't checked that yet. Could this be a missconfiguration or something that I'm doing wrong?

Que inseto minúsculo é esse?

Já faz um tempo que eu me mudei pro apartamento novo do meu pai aqui em SP-SP, e desde o primeiro dia até hoje, eu sempre vejo umas bolinhas pretas / marrons andando na parede do meu quarto ou no teto (e as vezes no rodapé), e quando eu me aproximo, dá pra ver esses insetinhos.

​

É um apartamento bem antigo mas que foi reformado do zero, e nos primeiros dias tinha um monte desses andando no teto, mas ao longo do tempo depois de várias limpezas e depois de colocar tudo que estava no meu quarto anterior, a quantidade diminuiu bastante, agora eu só vejo 1-3 andando pela parede anoite ou de dia. Eu já vi duas variações, essa com pequenas asas e outra sem nenhuma asas, e eles simplesmente não reagem quando eu chego muito perto. Uma coisa que eu notei é que no verão eles simplesmente somem, só aparecem na parede e no teto no inverno, quando está muito frio e chuvoso / ou muito humido.

Which version of blender should I switch to with a rtx gpu and to avoid dependency errors or missing and What about the blender from Snapstore? Would that be okay?

I'm currently having some issues with the native version and I've been thinking about switching because the native version only has CUDA and not OptiX (due to how fedora handles closed source software), I have a rtx 3060 so I think OptiX would be better for me.

I know that the tarball version comes with everything (I think) but it doesnt have auto-updates, and I also always install something from the internet / from outside the repos as a last resort, so idk if it'd be a good idea

There is an unofficial flatpak version (or unverified as flathub says) which is maintained by someone / the community and I dont know if it has a ton of issues because of sandboxxing and if it's ok to install it even if it's not supported / reviewed by blender.

And there is also a snap version, which is official and maintained by blender but I dont know if it'd be a good idea to have snap on my system just to install blender, and if doing that comes with many annoying issues.

What version are you guys using?

How does Snap work on Fedora? Is it okay to have it on my system, or could it break something or cause a lot of errors / headaches?

C6 Bank acusando o meu celular de ser inseguro e proibinando o meu acesso [S23 - Android 16]

A 1 semana atrás eu acordei e me dei de cara com essa mensagem, simplesmente do nada, a dois dias atrás estava funcionando perfeitamente, e eu já tentei de tudo

  • Reinstalei o aplicativo.

  • Tirei do Secure Folder / Pasta Segura (ambiente isolado do Samsung que age como um segundo celular e segurança top de linha, sempre deixo aplicativos sensíveis lá dentro, como bancos, e nunca me deu problema) e testei fora, continua dando o mesmo erro.

  • Desinstalei vários aplicativos e fui testando para ver se o c6 não estava cismando com algum deles (todos os aplicativos foram instalados pela Playstore, não tem nenhum de fora).

  • Opção de Desenvolvedor sempre esteve desativada.

  • Celular não é rootado, original (comprado diretamente pela Samsung) e certificado pela play protect.

  • Celular está com as atualizações mais recentes.

Mesmo apos tudo isso continua me dando esse problema, eu simplesmente não sei mais o que fazer, não consigo ver meu saldo nem nada. E eu estou começando a achar que ou é culpa da Samsung (teve a atualização para o OneUI 8.5 recentemente e a do patch de segurança mais recente) ou do proprio c6 bank, alguém que tenha um Samsung está sofrendo a mesma coisa também?

Celular: S23 (base)
Modelo: SM-S911B
Android: 16
OneUI: 8.5

Eu simplesmente estou a dias sem conseguir acessar esse banco e não sei mais o que fazer, e infelizmente não tenho outro celular para testar e não quero formatar do zero, por conta de tanta coisa que tenho aqui (e vai que mesmo formatando continue com esse problema). Eu tenho muita raiva desses bancos que tem esses sistemas de segurança muito restritos, eu tenho outro banco digital no mesmo lugar que o c6 e ele está funcionando perfeitamente, eu sei que a culpa não é do meu celular.

Pelo visto vou ter que tentar ligar pra eles ou fazer de outra forma, já que eu não tenho mais acesso ao chat (já que não consigo mais entrar no aplicativo), a última vez que tentei entrar em contato com o c6 eu quase perdi meu dia tentando conseguir um atendente humano em vez da porcaria da IA.

How to backup system before a clean clean install to remove mess or fix issues?

I have Fedora KDE Plasma on my computer, and I still haven’t figured out a good way to back up certain configurations (Blender, for example), a list of the Flatpaks and RPMs I’ve installed, and a custom Flatpak installation on my secondary SSD. How do you guys backup your stuff before performing a clean reinstall? Is there any kind of automation or command for it, and you dont actually need to wipe your secondary drives when reinstalling linux, right?

My system:

500gb nvme -> fedora, rpm, system flatpaks
1tb ssd -> flatpaks(custom installation=ssd1), rpmfusion steam games, appimages
1tb hdd -> vscode + blender project files

I'd like to achieve a way to backup some package configs, system configs (custom flatpak, fstab that with my secondary ssd and hdd) and other stuff, a quick way to reinstall rpms and flatpaks installed by me (system & custom install), I also have some systemd configs for my rclone + koofr setup (I use rclone to sync all my hdd files to the cloud, but that's the only thing I've been doing so far).

System Monitor only displaying the “Name” column - Fedora 44 with KDE Plasma

The system monitor isn't showing any columns other than the “Name” column; the columns work, but the headers are missing, with the exception of the “Name” column.

I’ve already tried editing and re-adding them, but they still don’t show up.

Is anyone else experiencing this bug?

This is happening with the application and process display style.

I don’t remember changing anything, and it seemed to be working fine until two days ago. Do I need to do something, or is this really a visual bug and something broke after an update?

Official Appimage or Community Maintained flatpak? - Fedora Linux

Lately I’ve been using the official Obsidian AppImage, but I wanted to try Flatpak because of its sandbox (which improves security a bit more when it comes to plugins) and see if it works well on my system. The website says that Flatpak is maintained by the community, is it still supervised by the Obsidian devs, or not?

Do you use the flatpak version or the AppImage version?

And I know you can isolate the AppImage with Firejail, but I haven't had time to learn how to use it yet, and maybe Firejail would break Obisidian

Corsair Frame 4000D annoying gaps and build quality

Hey, so I got a Corsair Frame 4000D because of the fact that it has a much better space than my previous one (gamemax bufren C1) to hide all the cables and not make a total mess (funny non-modular psu), it's extremely easy to reach stuff and clean inside the case thanks to its modularity and also because it's still not that heavy company to my friend's case that is 2x bigger than mine.

The case is awesome (and I got it with a pretty good discount) but the only thing that is annoying me are these gaps and those other slightly odd parts that should be properly aligned but aren't.

Especially the large gap under the tempered glass, I was installing a brand new ssd that I got and I didn't realize that until I put the tempered glass back in, annoyed I tried to remove it and put it back again but it stays like that, I never released it, a ton of dust can get inside with a gap like that.

Does your Corsair 4000D case have these too, or did I just get a bad batch?
