Dolphin
Dolphin is the KDE desktop's file manager. When using dolphin without KDE, you may want to install some optional dependencies.
Troubleshooting
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)
];
