Why do I get "Permission Denied" after installing flatpak?

Nyxt

I've installed the flatpak on NixOS 23.05 and I get a blank screen and this:

applications installed by Flatpak may not appear on your desktop until the
session is restarted.

I installed like this.

flatpak --user remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install flathub engineer.atlas.Nyxt

Which command are you using to start Nyxt?

Can you show me the output of flakpak list?

If you're on NixOS, I'd recommend installing Nyxt via nix instead of the Flatpak. Nonetheless, @jmercouris is able to run the Nyxt Flatpak on NixOS so the issue is probably coming from your side.

To start, I use:

flatpak run engineer.atlas.Nyxt

flatpak list | tee
Nyxt    engineer.atlas.Nyxt     3.9.0   stable  user
Mesa    org.freedesktop.Platform.GL.default     23.2.1  23.08   user

GNOME Application Platform version 45   org.gnome.Platform              45      user
[b0ef@ximian:~]$

I also don't want to use Nix to install, cause latest version there is .7

It seems related to your Nvidia hardware. What happens if you start via flatpak run --env=WEBKIT_DISABLE_COMPOSITING_MODE=1 engineer.atlas.Nyxt?

I'd strongly recommend requesting an update from the nix maintainers. Email one of the maintainers (NixOS Search).

Yes, that works;). Thanks. I will ask about why it's so far behind in the NixOS forum;)
