Dolphin
Dolphin is the KDE desktop's file manager. When using dolphin without KDE, you may want to install some optional dependencies.
Troubleshooting
Wayland
By default, dolphin by itself is not packaged with wayland support. This may cause you to get an error like this:
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
To get wayland support, add the following package:
/etc/nixos/configuration.nix
environment.systemPackages = with pkgs; [ kdePackages.qtwayland ];
Icons
By default, dolphin by itself is not packaged with support for svg icons. This may result in blank icons.
To fix it, simply add the following package:
/etc/nixos/configuration.nix
environment.systemPackages = with pkgs; [ kdePackages.qtsvg ];
KIO-Fuse
If you need to mount network shares you can use KIO-Fuse:
/etc/nixos/configuration.nix
environment.systemPackages = with pkgs; [
kdePackages.kio-fuse #to mount remote filesystems via FUSE
kdePackages.kio-extras #extra protocols support (sftp, fish and more)
];
