How To Disable GTK3 Client-Side Decorations (Header Bars)

Starting with GNOME 3.10, some GNOME applications have switched to « header bars » or « client-side decorations« . These CSD (client-side decorations) don’t work properly in some desktop environments / shells – for instance, in Ubuntu 14.04, Unity doesn’t support CSD and because of this, some applications look broken. Luckily, there is now a relatively easy way (unofficial) of disabling client-side decorations. Read on!

In Ubuntu, Nautilus and a few other GNOME apps are patched so they don’t use client-side decorations under Unity. However, not all applications were fixed – here are a few examples:

Encrypt DNS Traffic In Ubuntu With DNSCrypt [PPA]

DNSCrypt is a protocol for securing communications between a client and a DNS resolver, preventing spying, spoofing or man-in-the-middle attacks. To use it, you’ll need a tool called dnscrypt-proxy, which « can be used directly as your local resolver or as a DNS forwarder, authenticating requests using the DNSCrypt protocol and passing them to an upstream server« .
I wrote about DNSCrypt before but some things have changed since then (127.0.0.1 can’t be used by DNSCrypt any more on Ubuntu because that’s used by Ubuntu’s local DNS cache, there are no Linux binaries available for download, etc.) so this is an update for Ubuntu users who want an easy way of installing / using it.
