Configure OpenVPN with the KDE connection editor

Some VPN providers like NordVPN already provide OpenVPN configuration files (*.ovpn). The configuration files for NordVPN can be downloaded here.

This is the easiest way to configure a VPN. Just download the .ovpn files. Open the KDE Connection Editor, Add a new Connection an click on “Import VPN”.

Select one of the .ovpn files you downloaded, click OK, and if it asks you if you want to add the certificate, click Yes.
Edit the new VPN-Connection, change the connection name and enter Username and Password of your Account (if you can’t enter your password, click on the symbol to the right of the eye in the password-field, it maybe is set to “Ask for password every time”).

Sometimes you have to change the Settings in the IPv4 Tab too — this depends on your Distribution.
You will have to change Method to “Automatic (Only addresses)” and manually set the DNS-Server (8.8.8.8 is the Google DNS-Server, you may want to use another one).

Now your VPN should work 🙂

Fedora – Dark KDE-Theme and GNOME-Applications

If you select dark Themes like Breeze Dark (Color and Symbols) in the KDE Systempreferences, you will notice that it will not work out of the box with GNOME (gtk) Applications like Firefox and GIMP. While GIMP and most other gtk-Applications are still useable – they just don’t really fit in and are still light-grey –  it is really horrible with inkscape:

Notice that the symbols on the left are not identifiable.

To fix this, you will have to change the gtk-theme too. The options to do that are not enabled per default, you will have to install kde-gtk-config (and if you want the Breeze theme, also breeze-gtk) with

dnf install kde-gtk-config breeze-gtk

. Now you have a new entry named „GNOME Application-Style“ in the Systempreferences.

Change everything to Breeze-Dark, make a restart and your GNOME-Applications should be fixed.

If there are still some flaws, you will have to edit ~/gtkrc-2.0 (for gtk-2.0 applications) or the theme in /usr/share/themes/<Your_Theme_Name>/Gtk-3.0/gtk.css (for gtk-3.0 applications) manually.
For example, if you add this in ~/gtkrc-2.0, it will change the tooltip color:

style "gnome-color-chooser-tooltips"
{
bg[NORMAL] = "#FFFFAF"
fg[NORMAL] = "#000000"
}
widget "gtk-tooltip*" style "gnome-color-chooser-tooltips"
