The application can't open epub files anymore - Arch Linux about foliate

It's a WebKitGTK/Nvidia problem. See

Adding the kernel parameter nvidia_drm.modeset=1 fixed the problem for me.

I've tried adding that parameter and I get a different error now, and a different Foliate behaviour. It still doesn't show the eBook, though, but it doesn't hang. It's just blank.

Is it still Nvidia's fault?

I'm using foliate-git from AUR, maybe you can try that.

Thanks, using foliate-git works. Albeit in a weird way, as in I can't access any preferences, I can only switch from light to dark mode and that's it. ALso the gtk buttons look different (which I don't care but still). At least the books are readable.

I'm not sure this is an Nvidia bug at this point. If it is, it only manifests itself with Foliate.

I will have to look for an alternative.

It's probably a WebKitGTK bug on Nvidia.

I don't have Nvidia, and v2.6.4 works for me on Arch Linux.

I can't access any preferences, I can only switch from light to dark mode and that's it.

If you're talking about the "Preferences" item in the main menu of the library view, that indeed doesn't work, as it's not implemented yet (among other things that are still missing from the GTK 4 rewrite).

There are some preferences, though, that you can change in "Font & Layout Settings" in the view menu.

ALso the gtk buttons look different

That's just GNOME's new Adwaita stylesheet for GTK 4, which looks different from the GTK 3 version.

Fair enough. Thanks.

Starting foliate with WEBKIT_DISABLE_COMPOSITING_MODE=1 fixed the problem for me.

I ran into this issue trying use webkit2gtk on arch linux (with an nvidia card) and I was able to fix it without setting WEBKIT_DISABLE_DMABUF_RENDERER=1.

Here is how I fixed it:

1. Check if you have modesetting enabled via

    cat /sys/module/nvidia_drm/parameters/modeset
   

2. If you see printed N then you need to enable it with

    echo options nvidia_drm modeset=1 | sudo tee /etc/modprobe.d/nvidia_drm.conf
   

3. Restart your computer
