Solution : install thunar

Dolphin is under constant development and their software engineers have a vision how a file manager should work. At some point in time they decided that security wise it is not opportune to open up a file manager — dolphin as root. The potential harm, a user can do, is huge.

The developers have hard-coded into Dolphin that it can not be run as root.

Our best solution for now is to install thunar and use the custom actions from ArcoLinux to open up a folder as root.

See the image above.

Install thunar with

sudo pacman -S thunar

In the video you will see a new folder in dolphin called “root actions”. We installed that in this article.

To get the very last updates for Xfce-Thunar you need to install this package and run the skel command afterwards.

It all depends with what iso you started out whether you need to do this.
This package will install “open folder as root” in thunar.

sudo pacman -S arcolinux-xfce-thunar-git

Plasma Challenge

You can follow our tutorials based on either of two iso's.

1. ArcoLinuxB Plasma (recommended)

We record the plasma video's on an SSD installed from the ArcoLinuxB Plasma iso.
You can either create your very own ArcoLinuxB Plasma iso following this tutorial or download it from Sourceforge. (ArcoLinuxB-plasma-18.11.2.iso of 4.3 GB - games included)

2. ArcoLinuxD Plasma

You can also use the ArcoLinuxD iso and then install Plasma with the help of the github scripts. This will not be an exact copy of the iso.

Learn about the Plasma desktop and enjoy it.
