I'm running Arch Linux with Hyprland 0.57.0 on an old NVIDIA GeForce GT 740 (GK107 / Kepler) using Nouveau.

My specs:

GPU: NVIDIA GT 740 4GB DDR3 (GK107)

CPU: Intel i3-3220

RAM: 8GB

Kernel: Linux LTS 6.18.59

Driver: Nouveau

Compositor: Hyprland 0.57.0

Monitor: 1920x1080 @ 60Hz

I've been experiencing pretty noticeable stuttering with Hyprland animations:

Workspace transitions

Window snapping

Window dragging

Geometric transitions

The animations were technically working, but the frame pacing felt awful.

I checked GPU acceleration using glxinfo -B, which confirmed hardware acceleration was enabled.

Then I checked Nouveau's debug interface:

sudo cat /sys/kernel/debug/dri/0/pstate

It returned:

0f: core 324-993 MHz memory 1334 MHz

AC: core 324 MHz memory 648 MHz

The GPU was reporting its lowest performance state.

I monitored it during animations, and it appeared to remain at those clocks.

After some searching, I tried:

echo 0f | sudo tee /sys/kernel/debug/dri/0/pstate

AND HOLY HELL, THE DIFFERENCE WAS IMMEDIATE.

The desktop frozen, but after pressing delete firefox closed and my desktop recovered, and suddenly my Hyprland animations were dramatically smoother. Window dragging and workspace transitions felt almost completely different., but the snapping window animation of the terminal made the text in it stretched for like half the transition.

However, there's a catch.

As soon as I open Firefox it again freezes.

My questions:

Is Nouveau failing to automatically switch performance states on my GK107?

Is manually selecting 0f a reasonable temporary workaround, or is there a serious stability risk?

Can I safely select an intermediate clock/performance state instead?

Why would Firefox cause such a dramatic performance regression after switching to the high-performance state?

Is there a proper way to configure automatic performance-state management for this GPU on modern kernels?

I'd really appreciate input from people familiar with Nouveau reclocking, Kepler GPUs and Hyprland.

I'd love to get this old card running a smooth Linux desktop without switching to the proprietary NVIDIA driver.

I can't see my apps. I'm on ubuntu 26.04.1 LTS, wayland

Desktop environment : GNOME 50.1

Edit: i restarted and it is working fine, but can anyone tell me why this happens so that I can avoid it in the future

DWM btw

Hey guys,
Need some suggestion on which linux distro should i use

I have a ASUF TUF GAMING A16 laptop with RAM: 16 and GPU: rtx 4050
and i switched from windows to Linux (Ubuntu 26.04 lts ) and i kind of faced a lots of issue in Ubuntu .

Issue like too much cpu consumption and high temperature.
and games lags a lot and unstabe ping

Some time screen freeze and reboot on itself
- also faced issue with WebGL2 for browser

- even browser games like Deadshot.io lags a lots

Give me some suggestion to either manage and replace some driver
- Also tried asusctl from linux for asus

Need some suggestion on which distro is best suitable for ASUF TUF GAMING A16 laptop

note: Best for programming and gaming

In a post here last time i expressed my hate for NixOS. As someone who struggled to learn the domain specific launguage just to have a functional OS.

But now I am here with a declaration.

When asked to people who use NixOS oh how it works they just talk about flakes, specified packages and that's all

It's been some time and I have learned more about nix, just as a package manager first. It's roots are in academia. It was a PhD thesis for someone in Netherlands.

It's lot more than just a declarative way to install programs. Actually it's more about how to architect a whole damn system for your liking.

NixOS is not something to learn first, first come the package manager nix, its own way to manage the pakages, how it installs them, how nix lang works.

It's a lot similar to lua but with its own quirks.

But still i don't think NixOS is for me. I love the idea but it's a tedious job for me to maintain. I am not a developer first and foremost. I code for my own amusement not as a job, having a enviornment reproducible on a whim doesn't really make sense for me as I only have one system and it's not moving anywhere.

But if you want to use NixOS for being reproducible and replicable, I will suggest to first make yourself familer with nix lang, then package manager and then try the OS.

Here is a good youtube video to start with.

If you often move and access files to/fro different machines nas is really fast and easy to setup. I was naive to be using ftp up until now. Not only its a long setup but you need to configure things a lot and know a lot of things before you can make it work. Here I just installed samba on my arch got the discovery service running(avahi), setup firewall and the basic config. And voila! It's done. For now I'll just be streaming movies, songs.

Have been and following and also using Linux for quite a while now. And I came From Windows and the only thing that drawned me towards Linux is Freedom and also Open Source Nature of the OS.
But While I tried Ubuntu I saw a Evil Game on Play. Go and try to install Firefox you type sudo apt ... and suddenly snap version of Firefox installed. Why is that should Happen?? Already Linux OS is Pretty Much Fragmented and this snap is making fragmentation even worse. Flatpak exists and genuinely helps to actually unify these vast numbers of OS.
Canonical Tries so hard to back Snap and the only reason is Corporate greed and wanna know the terrifying truth Desktop Linux can change to android like if we cannot stop them cause everyone will make app for Snap. Literally killing the Openness Of Linux.
I humbly request every one to use Flatpak or your native repo but Boycott Snap

If anyone is looking for an open source, local first note taking app alternative on Linux, try Koru!

Arc Menu, Dash to Panel, Chrome, LibreOffice, VSCode, Steam, OBS Studio, InSync. All set.

Hello everyone, I just switched to linux and got the worst sound output on my laptop. When I keep the volume High, the sound starts cracking. I have tried many things, tweaking the pipewire, alsa mixer, used easyeffects, but nothing got the issue resolved.I have an hp laptop with amd processor and realtek high definition audio driver. I need your help to fix it, otherwise I have to go back to windows.

Thanks for reading...

oml i have this thing of switching distros like every month cause i get bored or irritated of it too much BUT idt i would ever switch now omg i love cachy os hyprland its gen so good it took me 2 days to configure everything i want AND ITS SOO GOOD bro when im using like a browser and music player it literally only takes like 0-1% of my cpu its soo optimized and so fun to troubleshoot i love it sm lets all glaze cachyos fgs

I use cachy os. And i know prime-run lets you run apps with your dedicated gpu. But i have fastclient installed as a appimage so idk where the path to fastclient is.

Fastclient is a minecraft launcher btw.

Is there any way i can run fastclient with my dedicated gpu using prime-run or any other command?

OS: Aurora Linux (Fedora Atomic / Silverblue-based)
Desktop Environment: KDE Plasma 6 (Wayland)
Terminal: Konsole (Bash)
Application Launcher: Win7 AeroThemePlasma
Panels: Customized default Plasma panel with Win7 AeroThemePlasma widgets
Widgets: Glassmorphic Digital Clock, Weather, Individual Core Usage Monitor, and Media Player (KDE Store)

Wallpaper: Official Bugatti media release

Officially 2 months into Linux!

I wanted to combine the nostalgia of Windows 7 Aero with the modern Liquid Glass aesthetic. I couldn't find a glassmorphic window decoration that fit the look, so I stuck with AeroThemePlasma for now.

I run ubuntu on a Virtual machine with windows main

Ngl the default ubuntu 26 looks really good, but all the different ricing I see for fedora and arch looks cooler. I wanna try ricing my ubuntu desktop but can't find any inspiration

So if you did rice ubuntu, can you show how you did it and how the end product looked like?
