Install GeForceNow on Desktop Linux/Non SteamOs devices

Guide for installing GeForceNow on Desktop Linux

With GeForceNow now being available for Linux we can now use the service with optimal performance.

Unfortunately Nvidia only officially supports SteamDeck and during getting this to work on my systems I had to get through some hoops that i want to share here.

First of all the app Nvidia provided is just a normal Flatpak app so the installation is relatively straight forward.
We will not use the official binary that Nvidia proved here, we can install the Flatpak app ourselves.

Just for reference im on PopOs 22.04 but since this is a flatpak it should work the same for everyone.

The guide assumes you have a working flatpak installation.

Installation

Install runtime

First install the runtime that GeForceNow uses, high chance that this is already installed.
The official installer installs this with the --system flag but I find this unnecessary so we install it as user like everything else.

flatpak install --user flathub org.freedesktop.Sdk//24.08

Add Nvidia repository

flatpak remote-add --user  --if-not-exists GeForceNOW https://international.download.nvidia.com/GFNLinux/flatpak/geforcenow.flatpakrepo

Install GeForceNow

flatpak install --user GeForceNOW com.nvidia.geforcenow

That's it you should now be able to launch the app.

Troubleshooting

Some issues I encountered and how I worked around them.

GeForce now encountered a problem and needs to be reinstalled

I encountered while testing this in a VM. The application failed because some GPU features where not available. On real hardware I had no issues. However, if you encounter that check these log files.

cat ~/.var/app/com.nvidia.geforcenow/.local/state/NVIDIA/GeForceNOW/geronimo.log
cat ~/.var/app/com.nvidia.geforcenow/.local/state/NVIDIA/GeForceNOW/GeForceNOW.log

I'm on a full AMD system, I could imagine Nvidia GPUs might make some trouble since the SteamDeck uses AMD.

Logging in not possible (Endless loading spinner)

This is because GeForceNow is failing to open the hosts browser. Luckily Nvidia writes the oauth url it wants to open into a logfile.
You can extract the line with this command.

tac ~/.var/app/com.nvidia.geforcenow/.local/state/NVIDIA/GeForceNOW/console.log | grep starfleet/o-auth | head -n 1

Then paste it into your browser and continue as you would normally.

Network Test Failing

For me the Network Test always failed and claimed there was no connection to Nvidia servers. Even though the app was clearly online. I'm usure why this happens. What I ended up doing is:

• Click the Burger Menu on the Left Top Corner
• Go to Settings
• Gameplay
• Change Streaming Quality Mode to Custom

This will skip the network check.

Window not opening on Wayland

When the GeForceNow App is not opening and you are under wayland try removing the wayland permission from the flatpak to force it thorough XWayland.

flatpak override --user --nosocket=wayland com.nvidia.geforcenow 

End

Thats it, for me it worked flawlessly afterwards. If you have any additional issues and fixes write them in the comments so we can update the Gist.

Does anyone know a way to force or persist AZERTY keyboard layout inside game launchers (Steam / Battle.net) when using GeForce NOW on Linux?

@krxdow Same for me with BÉPO or AZERTY layouts. GFN uses an English version of Steam with a QWERTY layout, and I know no workaround for this. Many people already complained about this in the GFN forum.

Yes, I confirm this is not Linux nor SteamOS specific. https://gist.github.com/Mihitoko/bd76340e56e78ec972c8a1365abb0d55?permalink_comment_id=5812552#gistcomment-5812552 If you find a solution somewhere, please share it here, i will do the same :)

I've just tested again on Chromebook and there is actually an option for keyboard layout that is working !
I think it's the Android client since I also got the same option available on my smartphone (but not tested).

anyone know how I can connect to my epic account? i just get the popup saying a browser tab is open, finish connecting your account. but nothing happens

thanks

Updated script for fedora, with the right geforce client version, the latest update broke everyhting.

Hi guys, installed GeforceNow from here ubuntu but i cannot start a game. become Network Test window and it say that i can not connect to the nvidia server, and iam Change Streaming Quality Mode to Custom already, but that doesn’t help.
What can i do to skip that Network Test Window?

The installation itself works, but I don't have the 4k option and in the terminal, I see: [34:62:2026-01-03/ 18:05:46.916:ERROR:registration_request.cc(291)] Registration response error message: DEPRECATED_ENDPOINT Callback requested, but no callback function provided!
Could it be that the device is still not accepted as a Steamdeck?

I found the issue. In the install script, geforce now is installed with the user flag. However on Debian, the downgrade to the version you need root permission, which is why running flatpak update --noninteractive -y --user --commit=0d56... did not actually downgrade the version. For me it worked installing and then downgrading with the --system flag and not the --user flag.

Updated script for fedora, with the right geforce client version, the latest update broke everyhting.

Hi Dear, can u please create script for ubuntu?

Thank you

I found the issue. In the install script, geforce now is installed with the user flag. However on Debian, the downgrade to the version you need root permission, which is why running flatpak update --noninteractive -y --user --commit=0d56... did not actually downgrade the version. For me it worked installing and then downgrading with the --system flag and not the --user flag.

Hi Dear, after downgrade over terminal i become working version without network problem, but with no 4k and 120hz option , max 1080p60hz , iam ultimate user.

Can u modify ubuntu script with right (working 4k and 120hz version) please?

@d4vid1 For me this worked:

Installing:

flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install --noninteractive -y --system flathub org.freedesktop.Platform//24.08 || true
flatpak install --noninteractive -y --system flathub org.freedesktop.Sdk//24.08 || true
flatpak remote-add --system --if-not-exists GeForceNOW https://international.download.nvidia.com/GFNLinux/flatpak/geforcenow.flatpakrepo

flatpak mask --system com.nvidia.geforcenow

Then I start geforce now with this script:

#!/bin/bash

echo "Starting GeForce NOW with SteamOS os-release file and SSL certs..."

flatpak run --system --command=bash com.nvidia.geforcenow -c '

That's really all I did. It is really important that you use the flatpak update to downgrade the app, otherwise it will still be on a newer version. Afterwards you can use the mask command to fix the current version to avoid auto upgrading. Hope that helps.

Hi bro,

i follow ur howto, but i become this

LANG=C flatpak update --noninteractive -y --system --commit=0d56051d6c9c81177f685a988d666fa12b647ca25f994e9bb378d4c9305b10c2 com.nvidia.geforcenow

Nothing to do.

i think that commit doesn’t exist more..
it will not downgrade version.

thnx in advance

Hopefully GFN will natively support Linux soon 🙏 https://videocardz.com/newz/nvidia-geforce-now-to-gain-native-linux-support

Hey, does this updated version of the script work to get 4k 120fps on Fedora with the latest app version? If so I'll update it in my gitlab repo :)

By the way, apologies to everyone if I'm slow updating https://gitlab.com/anthrgk/geforcenow-installer-linux
I know the batocera and fedora version are outdated there, but I only use Arch so I rather be cautious before updating the installer (unless someone here provides the full script and explicitly confirms that it works with the latest app version AND with 4k 120fps)

Apologies

yes, it's already written by me there: https://gitlab.com/anthrgk/geforcenow-installer-linux/-/tree/main/ubuntu

I'm having a screen tearing issue on Ubuntu tried messing with vsync setting but all the same result it usual one or two lines a top half of the screen

somebody able to run these app on integrated intel VGA?

as 8 Jan 2026 I have intel HD 530 (integrated gpu) and it work out of the box but I have a screen tearing issue on 60hz monitor with fps set to 60 and tried all vsync settings but no luck.

Does anyone have any fixes to the scrolling issue? It seems that now scrolling doesn't work and also if you use two monitors it doesn't capture your mouse inside of the game unless you do the virtual keyboard & mouse through CTRL + G.

You can fix this with the --force-grab-cursor in the gamescope command

Hopefully GFN will natively support Linux soon 🙏 https://videocardz.com/newz/nvidia-geforce-now-to-gain-native-linux-support

GeForce now is now officially supported on linux desktops by Nvidia 🎉 You can download the beta here.
It works perfectly on my Ubuntu 25.10 machine. Just do a flatpak uninstall geforcenow before launching the Nvidia setup if you already installed the binary following this gist instructions.

@Mihitoko Thanks for this gist, it has been very useful 👍

Tip: you can remap controller buttons (specifically to swap A/B and X/Y) by setting the SDL_GAMECONTROLLERCONFIG environment variable. The example below is for the 8BitDo Pro 3 Receiver, but you will need to generate a unique mapping string if you are using a different controller (eg. with jstest-sdl)

Note: GeForceNow uses an embedded version of libSDL2.so. So, the mapping string required here might differ from strings generated, if your tools use SDL3 or an SDL3-to-2 shim.
