Is there an actual practical way to FULLY undervolt a NVIDIA GPU on Linux?
I used to do that on windows and it easily got the temps 10 degrees lower, but I have recently switched and can't find a practical way to do it in full control on Linux.

I'm on Pop!_OS and my GPU is *RTX 2060* with *6GB VRAM*.

I really need to undervolt my GPU since it gets very hot under load while gaming (85 c was the highest I recorded which is quite a dangerous temp for the GPU itself)
On the Windows NVIDIA App, These were my settings :

Power Maximum -> 90%

Voltage Maximum -> 85%

Target Temperature -> 70 c

I have enabled CoolBits 28 (I have also tried its other values as well) and managed to manually set the Power Maximum to 90% and created an aggressive fan curve profile using GreenWithEnvy, but it didn't help quite much it only got 2-3 degrees lower, the Voltage Maximum was the most important part of it which I couldn't find a practical way to achieve. Do you guys have any suggestions for me?

I'm trying to use the Plutonium client for various Call of Duty games but wanting it to launch through the official library page for the game. For example when I click play on Black Ops 2 Zombies I want it to launch the Plutonium client. I was able to get this working on my Windows PC easily but it's a lot harder on a Steam Deck considering Plutonium doesn't support Linux. However there is a workaround to this which is using Plutonium Deck Launcher (this also allows me to play the client offline). However if i try to launch it via Steam Launch options it isn't working since it needs access to the rest of the files.

I tried making dragging the PlutoniumDeckLauncher.exe to the Black Ops 2 Steam folder and selected "Link here" then used this in the launch options.

cmd=( %command% ); cmd[-1]="$STEAM_COMPAT_INSTALL_PATH/PlutoniumDeckLauncher.exe"; "${cmd[@]}"

However it left me with this

Is there any way I can get Steam to recognize all of the files for the Client Launcher via the Launch Options?

I'm not too familiar with Steam Launch options so any help would be much appreciated🙏

PS: Yes I'm aware that I can just add it as non-steam game (which I am doing for now) I just thought it would be nice if I could launch it and have all my playtime connected.

Edit: I also need to add this command to the launch options.

PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%

Just not sure how I would navigate around using multiple commands simultaneously either.

Also I'm needing to use GE-Proton10-25 in the Steam compatibility options which isn't an issue. Just mentioning it as I'm not sure if this will effect anything.

Hey everyone,

I’m part of an unnamed anti-cheat company, and I’m trying to get a better understanding of a recurring sentiment in gaming circles: the idea that any kernel-level anti-cheat is automatically “spyware,” a “rootkit,” or otherwise malicious.

I’d love to hear your thoughts on a few things: 1. Why do so many players assume kernel-level = malicious? 2. Is there anything anti-cheat developers can realistically do to alleviate these concerns?

For context, most kernel-driver logic is kept proprietary not because we’re hiding shady behavior, but because exposing too much info makes life easier for cheat developers. Still, I get why people are cautious, and I want to understand how we could better communicate our intentions without compromising security.

Rather new to Linux beyond my Steam OS on my Steamdeck and a few Ubuntu tests years ago. I wondered if anyone had any thoughts as a gamer and as one who does some college work and such. How's gaming? Bazzite is much easier for this but not as performative, right? Quality of life differences? Performance overall?

I really want to ditch Windows 11 as much as I can but since my GPU is Nvidia, I figure I'll have to dualboot for some programs and games anyhow.

Hi, I use bottles to play ETS2 and I've capped the max fps at 24 using DXVK_FRAME_RATE=24 %command%.

Yesterday, after creating and playing ETS2 on a new bottle, the DXVK_FRAME_RATE=24 %command% no longer works. While other launch options such as -nointro work perfectly.

Help. I AM having trouble with linux on my x17 r1 nvidia 3070. i installed kubuntu neon and it works well when I get into it it boots fine the first time, but the second time it didn't boot and it never can boot right again. I reinstalled a few OS to get here bazzite pop ubuntu etc and kubuntu worked well, but it only boots when I disable the drivers at the grub. I pressed 'e' and changed the line to: "earch --no-floppy --fs-wuld --set=root cd318437-8cf7-4fb7-8788-c408576693d0 /0/boot/vnlinuz-6.14.0-36-generic root=UUID=cd318437-8cf7-4fb7-878a-c40e576693d0ro rootflags=subvol=@ i8042.nopnp=1 i8042.nomux=1 i8042.noloop=1 text linux initrd /@/boot/Initrd.ing-6.14.0-36-generic_"

and it booted back into kubuntu. I checked my nvidia in konsole with success

Admin@x17r1:~$ lspci | grep -i nvidia\ 0000:01:00.0 VGA compatible controller: NVIDIA Corporation GA104M [GeForce RTX 3070 Mobile / Max-Q] (rev\ a1)\ 0000:01:00.1 Audio device: NVIDIA Corporation GA104 High Definition Audio Controller (rev a1)\ Admin@x17r1:~$ \ \

Help me fix this so my computer doesnt get stuck trying to boot anymore. Is this a 535 or a 550 driver kind of problem? Anyone else have this issue?

Hello,

I have a rx 9070xt in my system running the latest version of bazzite. The general consensus seems to be that HDMI 2.1 and with it 4k 120hz isn't possible on linux with AMD GPUs because of licensing issues.

Somehow I can select 120Hz with a 4k resolution when using my LG B4 over HDMI though. How is that possible? When playing it definitely feels like a 4k signal with at least 60hz. I tried to check that maybe chroma subsampling is the cause of this but so far my googling didn't return any answers on how to check that.

Maybe someone here has an idea what is going on?

Hello! I really eant to try out linux, and have been reading that some distros are not as good as others for nvidia support. What distro should I get to have maximum use/power/performance from my gpu?

Games I play: Rainbow 6 Siege Gta 5 Cities Skylines Garden Warfare 2 Minecraft

If some games are incompatible, thats fine, im planning to dual boot an unactivated windows for engineering studies and anticheat games

Thank you!

i tried using terminal to see and that's what it showed

qt.qpa.xcb: could not connect to display

qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb, eglfs, wayland, vkkhrdisplay, minimal, offscreen, vnc, minimalegl, wayland-egl, linuxfb.

Does anyone have a problem with constant jitter in CS2?

The game runs just fine, except for the lagging, it's always around 20ms with packet loss reaching 10%.

Everything works fine on my system, network and drivers work flawlessly for everything except CS2.

I'm on Arch, with kernel 6.17.9, using Niri (Wayland).
Steam is the native version, not flatpak.
Mesa 25.2.7

I play a lot of games on ironman mode or single save modes or pvp games and have alt f4ed to save myself on countless occasions or just get out of the game.

How can I disable alt f4 in some way either in certain games or on my whole computer.

I tried keyboard shortcuts and disabled it but nothing changed. I'm on pop os

I'm playing FIFA 13 through Lutris on my SD. I looked through the c drive and couldnt find a folder for my in game settings and saves even though I have them when I play. Anyone know where it is? I'm just trying to update the squads to the last update for the game. Found a link here to the update. Where would I place it in the c drive? Thanks

I relied on AMD Eyefinity on Windows for years, especially for triple-monitor gaming. When I switched to Fedora Linux (Wayland + KDE Plasma), I discovered that:

Eyefinity doesn’t exist on Linux, Wayland doesn’t support a “single large surface”, and multi-monitor fullscreen gaming is nearly impossible.

… but after a lot of testing, debugging, and configuration, I finally reproduced Eyefinity-style triple portrait gaming under Linux using gamescope — including:

• 3360×1920 resolution across 3 portrait monitors
• proper fullscreen behavior
• no window borders
• no screen cut-off
• correct mouse input
• stable framerate (VSync 60)
• Unity Engine games working (Universe Sandbox)

Since this was hard to figure out, here is the full solution.

✅ My System

• Fedora Linux 43
• KDE Plasma 6.5.3 (Wayland)
• AMD Radeon Pro W5700
• 3× Portrait Monitors, combined resolution 3360×1920
• Gamescope (nested compositor)
• Example game: Universe Sandbox (Unity)

✅ Steam Launch Options

In Steam, set:

~/bin/gamescope-wrapper.sh %command%

🛠️ Create the wrapper script

Create:

nano ~/bin/gamescope-wrapper.sh

Paste:

```

!/bin/bash

systemd-run --user --scope --quiet \ gamescope \ --force-grab-cursor \ --mouse-sensitivity=1.05 \ --borderless \ --rt \ -W 3360 -H 1920 \ -w 3360 -h 1920 \ -- "$@" ```

Make it executable:

chmod +x ~/bin/gamescope-wrapper.sh

🧩 Why this solves the problem ✔ Gamescope simulates a “virtual Eyefinity monitor”

Wayland does not allow treating multiple monitors as one. Gamescope can, and creates a virtual 3360×1920 display the game believes is a single monitor.

✔ --borderless

Avoids native fullscreen logic (which restricts to one monitor) → Gives a clean fullscreen-style window without decorations.

✔ --force-grab-cursor

Fixes the major Unity issue: Cursor disappearing or becoming invisible when crossing monitor boundaries.

This makes the mouse stable across all 3 portrait screens.

✔ Realtime scheduling (--rt via systemd-run)

Improves frame pacing and input smoothness.

Optional, but recommended:

sudo setcap cap_sys_nice=eip $(which gamescope)

🖥️ Important KDE Setting (must be disabled for gaming)

KDE Plasma has mouse “edge barriers” enabled by default. This makes the cursor stick when moving between monitors.

Disable it:

Right-click desktop → Display Configuration → Screen Edges

Set:

• Top-left corner: No Action
• Corner Barrier: Off
• Edge Barrier Size: 0 px

This lets the mouse move freely across all three monitors.

🧭 KWin Rule (fixes incorrect starting position)

If the gamescope window appears only on monitor 2+3 instead of all 3:

Add a KWin rule:

• Window class: gamescope
• Position: Force → (0,0)

This ensures the window always anchors to the far-left monitor.

🎮 Final Result

• True triple-monitor gaming on Linux (similar to Eyefinity)
• Working mouse input (no disappearing cursor)
• Stable 3360×1920 rendering
• Clean fullscreen without borders
• Unity games work
• KDE edge behavior fixed
• Realtime scheduling for smoothness

This is probably the closest thing to Eyefinity on Wayland right now — and it actually works surprisingly well.

Good luck replicating my setup — I hope this helps someone out there.

Hey there, I have been struggling to re-install Battle.net onto my Linux system which is running Linux CachyOS. I have updated all the software, tried different software (see below photos of each program) with no success. Is there any fix to any of the programs, whether it be Lutris, Faugus Launcher or Bottles?

I was able to have it installed through Faugus Launcher yesterday, but now it just isn't working. I tried opening it multiple times with no success, then I uninstalled it and (attempted to) reinstall and have been encountering this issue repeatedly.

Faugus Launcher when trying to install Battle.net. Unsure why this is popping up. Does the same with Rockstar Games, EA Games and everything else. I have attempted downloading Faugus Launcher through Flatpak command and the KDE Discover Store.

Lutris gives me this error, despite uninstalling and reinstalling the application.

With Bottles, this happens. There have been the occasional times where I could open the application, but it gets stuck on the Update Agent has gone to sleep.

Hello. I've been using different Linux distros ever since I wanted to switch from Windows. I still struggle to understand the real differences in gaming between distros.

For example, I am currently using Kubuntu. Steam works fine in it, and I can play all games I have. Why would I switch to a more gaming-oriented distro like CachyOS? What would the differences even be?

And To be honest, the only real-world differences between distros are the Desktop Environments, in my experience

Hi guys!

I got bazzite installed on my computer and its working great. The GPU is Nvidia so I cannot use game mode due to some glitches so I have settled on booting to desktop then auto launching steam big picture. Does anyone know a way to have the dock hidden when booting?

Right now steam big picture is launching but the desktop is in like an overview mode until I click on steam.

I am using gnome.

Thanks in advance!

Garry's Mod is one of my top games, it's a ton of fun, and I knew that there were issues with it relating to Linux. I already had it at 64 Chromium, installed GMPatchtool, and also did that thing with the autoexec which gives you more performance.

However, for some reason, if I spawn into a map with a lot of stuff in it, the game tanks in FPS and basically becomes a slideshow. I know that my PC is capable of handling the demanding maps, yet since I got into Linux, once I enter the map, the WHOLE game lags, even if I go to a different map. Sometimes I quit out and the game returns to normal, and most of the time if I try that map again, it runs fine, but then I try another map and it lags again.

Is there a step I missed in making GMOD work good on Linux? Please help!

I have no clue if this is the best sub to ask this maybe but, since almost all searches on "vesktop reddit" turn to this sub and there's no official vesktop subreddit maybe I should try asking here (if there are better subs tho please advise me)

My country has in the past few months approved some stupid law like the OSA in UK, to go full in effect by March, so I decided to grab Mullvad to protect myself and my data from it, but it seems Vesktop simply refuses to work with it.

when starting my system, if Mullvad is on the application doesn't even start, but after disconnecting from Mullvad it goes through, but if I try connect again (and honestly, ahving to disconnect in the first place defeats all the purpose) simply NOTHING works, messages on any chat/server fail to load, can't switch between alts nothing.

I've tried 3 servers so far to see if it was a problem with the servers and seems it isn't.

am I doing something wrong?
