Dolphin
⤧︎
Disambiguation: Not to be confused with Dolphin Emulator.
Dolphin is the KDE desktop's file manager. When using dolphin without KDE, you may want to install some optional dependencies.
Troubleshooting
Open with menu fix
When using dolphin on other Desktop or Window Managers, the Open With menu may not show any applications.
A comprehensive solution can be found with rumboon's dolphin-overlay, but a more straight-forward fix would be to add the following line to your configuration file:
❄︎ /etc/nixos/configuration.nix
environment.etc."xdg/menus/applications.menu".source = "${pkgs.kdePackages.plasma-workspace}/etc/xdg/menus/plasma-applications.menu";
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 # needed since 25.11
kdePackages.kio-fuse #to mount remote filesystems via FUSE
kdePackages.kio-extras #extra protocols support (sftp, fish and more)
];
Install
❄︎ /etc/nixos/configuration.nix
environment.systemPackages = with pkgs; [
kdePackages.dolphin # This is the actual dolphin package
];
