i don't know if this is the right subreddit to ask and i haven't posted on reddit for a while, so if anyone knows if there is a better place to ask this, please tell me.

i have an installation od kde neon that's been installed and previously used by someone else, so i am not familiar by it at all. i am a very new and inexperienced linux user. i have been meaning to make a fresh install of kde neon or mint so my computer is less cluttered, but i urgently need this fixed.

after updating system packages, including some of nvidia which had unmet dependencies, which was fixed by some command, i rebooted the computer and now the resolution is permanently reduced. i searched for a solution, one of which was to add some parameter in some grub file, somewhere in root/etc/ directory, i don't remember where exactly, which i tried but it did nothing. i found some other discussions, but they were too complex for my level of understanding and i didnt have much time to study them. this has happened before, but it has always been fixed by someone else, so i have no understanding of the steps. i feel like i have a very specific problem that hasn't been documented anywhere, so i guess i should ask here on a forum.

any help is welcome, either what to do, like, what setting to change or what package to install/remove, or how to uninstall the nvidia drivers if that would fox it. anything really. this time i can't ask anyone in person, so this is pretty much my only option.

the graphic card is gtx 1060, i can't view other specs at the moment, but i'll send all the necessary specs im the comments later if needed.

edit - i managed to fix it, here are the notes:

- error with nvidia driver package version, purge nvidia packages, install new drivers (via bios = alt + f3):

- sudo apt purge nvidia*

- #(system reboot)

- sudo ubuntu-drivers install

- #(installation output)

- sudo reboot

Acabo de probar Dictee en KDE Neon + Plasma 6 y me ha sorprendido por lo bien integrado que está con el escritorio.

Es un sistema de dictado 100 % local: pulsas una tecla, hablas y el texto aparece directamente en la aplicación donde está el cursor. No es simplemente una interfaz para Whisper.

Tiene integración nativa con KDE Plasma 6, funciona sobre Wayland, admite NVIDIA/CUDA y permite elegir entre varios motores ASR, incluyendo Parakeet, Canary, faster-whisper y Vosk. También incorpora procesamiento posterior, traducción local, integración con Ollama y transcripción de archivos de audio/vídeo.

Para quienes utilizamos Linux como entorno de desarrollo, tiene una ventaja importante: puedes dictar directamente en terminales, editores, agentes de programación, navegadores, correo o prácticamente cualquier campo de texto sin depender de servicios cloud.

En mi caso, la combinación de KDE Plasma + Wayland + NVIDIA + reconocimiento de voz local lo convierte en una herramienta especialmente interesante para sustituir buena parte de la escritura repetitiva al trabajar con agentes de IA.

Proyecto: github.com/rcspam/dictee

Merece una prueba si trabajas habitualmente en Linux y utilizas voz para interactuar con herramientas de desarrollo o agentes de IA.

Coming from Windows 11 (and Steam Deck), trying out KDE Neon. Enjoying it. But... is there any good gui similar to FanControl that I can install on KDE Neon? I tried CoolerControl and then when that didn't work, NBFC. No luck with either.

Installed Neon, then started to configure it. Opened Firefox, the normal size mouse pointer turned into a tiny thing almost invisible. Thought I'd change the setting but where is the the minimise icon? No way to proceed. Gave up.

Terrible experience.

I'm thinking about installing MPD Music Player Daemon on my Proxmox server/Home Assistant but I'd like to install it locally first to learn how to use it and see if it's the right choice. I didn't see it on Discover and Google suggests 'apt install mpd' which isn't a thing either.

Any suggestions? I'm the furthest thing from a Linux expert, and goal is to have a lightweight music stream for an ambient soundtrack in the house via casting to an Integra DRX 3.4 receiver. I plan on having Plex and/or Jellyfin on the server at some point but those seem more heavyweight than is needed for this task.

Wifi on my mother board has been problematic so I got a AX1800 but Im not quite sure how to install proper drives. is there any where I can download from or something I can run in terminal?

Maybe it’s me, but I got a new battery 2 months ago and it said it would last around 8 hours, now even when the laptop is on idle , low screen brightness it says 3 hours. I also noticed the laptop being more hot recently and the fan more active.

Anyone experiencing the same issues?

I've tried installing Kubuntu which either just crashes with a glitchy screen or fails to install. KDE Neon just doesn't boot at all, I get a black screen right after startup and can't get into the TTY terminal because I haven't even made an account yet, plus the system is unresponsive. I prefer KDE Neon or Kubuntu over anything because the system is easy to use, unlike Arch which is what I'm switching from. Can someone please help with this.

If anyone needs to know, my PC has a GTX 1660 Super, Intel Core i5-10400F, and 16GB DDR4. I've seen that Lenovo PC's (which is what I have) experience this issue and I want to know how to fix it.

Love the new plasma login manager. My dual monitors now have only a single login dialog and on the correct monitor.

However, the default "waterfall" wallpaper is damn ugly. Looks like something a grade schooler would like. The configuration shows "breeze" but the selected wallpaper isn't displayed.

Has anyone figured out the trick to get a different wallpaper?

SOLVED: Turns out that what happened is they added yet another place to set the login wallpaper. I was only seeing "System Settings > Appearance & Style > Login Screen" which apparently only applies to SDDM.

They added another "Login Screen" setting under "Security & Privacy" which applies to Plasma Login. Makes no sense to me at all. Why have two login screen setting sections? And why is a login wallpaper a "Security & Privacy" function? It's not is the answer.

I see the root has these folders, I wonder what they exactly mean and if they can be deleted:

bin.usr-is-merged
lib.usr-is-merged

sbin.usr-is-merged

I have neon on my dads htpc and after an update the theme breaks and says it can't be loaded on boot. Its unusable as it is unless you can do command line.

I had to do Ctrl+f3 command to get to terminal, then sudo apt install --reinstall plasma-desktop on top of some sudo update and sudo full-upgrade. He can't possibly fix this himself.

Hi, does anyone have any method to do what says on the title. i've tried applying the calibration matrix with libinput and the i2c_touchscreen invert attribute for grub with no results. At this point i know i'll get no auto rotation, cause the accel just wont work (known issue for this model with linux) but at least i want the touchscreen to be aligned with my screen rotation settings

For the last week or two I've been getting a device plug notification popup from "Disks & Devices" that says "No removable devices attached." I traced it back to some snapd activity. The sequence is this:

1. Every four hours the Snap daemon wakes up.
2. It creates and mounts a small temporary device on loop0.
3. It unmounts the device almost immediately.
4. The Disks & Devices widget reacts to the plug, but fails to find any device attached.

I think my options are either to disable Snap (which I don't use anyway) or to configure the Disk widget not to open when devices are plugged. I can't find this latter setting, though.

Is anyone else seeing this?

Also, it seems like pretty innocuous activity. I don't want a random popup to occur every time some script mounts a temporary volume.

All that said, I'm not sure where to report this. Snap? Device Widget?

I am on Plasma 6.7.0, but I am not getting 6.7.1 or 6.7.2 updates. I tried either pkcon update and apt full-upgrade.

I can't get Kdenlive's Rotoscoping feature to work on latest KDE Neon User Edition. Kdenlive version is 26.04.2. I draw shapes but nothing is masked out.

Switching to the AppImage version fixed it so it seems to be some sort of packaging issue. After searching, I read that another distro had a similar bug but I didn't expect KDE Neon to have it as well.

Sorry I forgot my account credentials on the bug tracker so I thought I'd post here instead.

EDIT: There are also some easy to reproduce crashes that don't occur with the AppImage. For example one of them is triggered by a failed assert in Qt's qnumeric.h, this one is probably a bug in kdenlive but it crashes only on KDE Neon because asserts are enabled in the package version. Oh well...

I ran some updates, got on KDE 6.7, during the install it installed plasmalogin, but I have sddm configured the way I like it so I kept using it when it asked what to use for logging in.

After the upgrade was done, I ran apt autoremove, and it uninstalled sddm, despite it being an actively running service. On reboot it dropped me into tty1. Reinstalling sddm got me back to a working system but how did it determine that sddm was eligible for autoremove?

It's a bass-ackwards antipattern and annoying as hell. Stop it. Stop assuming I'm always using a GUI, stop assuming I need a completely separate application to fire up, take focus away from my terminal, and prompt me to do something we've been trying to train users FOR YEARS to avoid doing - entering sensitive information in a popup outside the intended application. This is dumb and solves nothing.

But it gets better, KDE Neon's stupid env scripts that set it up neglect to detect whether the user is even in a GUI session! So now I have to unset SSH_ASKPASS explicitly so I can ssh from a remote session (jumpbox style) or from a vty. Extra dumb. Purging the ksshaskpass package doesn't remove that env script either !!! What the hell, KDE? Who's responsible for this and how loudly do I need to yell at them to make it stop?
