Oh sorry yeah I use the open drivers from here:

cat /etc/yum.repos.d/cuda-fedora43.repo

These are the components I have installed:

Hi @asrieldashie and @exist2resist
I have just released version 25.1.5 and added so that Xlibre also provides the same ABI version as Xorg and Xorg on the specific architecture. Can you try Xlibre with the Nvidia driver now?

I’m now able to install xlibre without issue. However, the nvidia driver (prop/open from Fusion, prop from official site) doesn’t seem to work properly for me, results in black screen when running anything that requires hardware acceleration.

24

You need to override it

Section "ServerFlags"
    Option         "IgnoreABI" "True"
EndSection
25

This unfortunately did not help for me in my case.

26

This shouldn’t be necessary anymore since it has become the default.

27

It looks like you have a dual GPU setup with both an Intel iGPU and an Nvidia dGPU. Is that correct? If yes, is there a specific reason you want to use the Nvidia DDX driver instead of the modesetting driver?

EDIT: I was researching a bit and this seems to be related to your issue: https://github.com/X11Libre/xserver/issues/1588

28

It seems that I’m having a same (or similar) setup with the author of the issue, I’m using a laptop with both kind of gpu. But disabling TearFree does not solve the issue for me, neither does setting it to use modesetting driver.

xorg.conf 
Section "Device"
    Identifier "nvidia"
    Driver "modesetting"
    BusID "PCI:1:0:0"
    Option "TearFree" "false"
EndSection

Section "Device"
    Identifier "intel"
    Driver "modesetting"
    Option "TearFree" "false"
EndSection

Also setting it to modesetting stop my internal screen from displaying anything after reaching the graphical interface.

29

Your cmdline has garbage in it

[2026-04-30 03:12:51] Kernel command line: BOOT_IMAGE=(hd0,gpt2)/vmlinuz-6.19.14-200.fc43.x86_64 root=UUID=f7915202-6c06-4bbb-a78b-254e86865666 ro rootflags=subvol=root rhgb quiet,nova_core,nova_core rd.driver.blacklist=nouveau,nova_core modprobe.blacklist=nouveau,nova_core

change

quiet,nova_core,nova_core

to

quiet

also install nouveau, it’s required for nvidia fallback

30

Try without any Xorg config. With modesetting it should find both cards automatically.

If you want any custom settings then only use Intel - no nvidia section. You can see my config here as example: my-ostree-OS/etc/X11/xorg.conf.d/20-modesetting.conf at main - anders/my-ostree-OS - PC-Rytteren: Source code archive

Kernel modesetting needs to be enabled to use the modesetting driver. You can check if it’s enabled with this command: cat /sys/module/nvidia_drm/parameters/modeset

31

I ran without any configs, the system boots but there’s no output on external display. Some games and applications seem to run with nvidia gpu, while some refuses to work. Picom crashes with glx backend, Muffin (on Cinnamon Desktop) doesn’t display anything and hangs the system or not drawing any window.

That fixed it for me with the latest open driver, thank you.

Sorry for the late reply.

I think it’s something that needs to be reported to upstream. It doesn’t seem to be an issue with the rpm packages but rather a bug in Xlibre itself. GitHub - X11Libre/xserver: XLibre Xserver · GitHub

34

@andersrh I attest that this COPR functions perfectly on Fedora 44 as of 06JUN2026. I presume that being on a Xorg-forward Fedora spin was the reason why it was so painless.

sudo dnf copr enable @xlibre/xlibre-xserver
sudo dnf --refresh update -y

Executing the above automatically swapped out all my Xorg packages for the equivalent XLibre packages. Reboot for safety’s sake (definitely not needed), log back in, and everything functions as expected. Tested out some Steam games, they work fine. GOG titles via Heroic, works fine. Cheers for the excellent work.

QUESTION: How closely does this COPR track with upstream XLibre on GitHub? I had some rough experiences daily driving XLibre long-term on Linux Mint because the third-party repo kept changing.
