  So, it looks like a duplicate of
  but this was on KDE in 2009 and I doubt it would have anything to do
  with it...

  Anyway, here is how to reproduce the problem:
  - Go to network-manager settings GUI (network indicator -> Network connections)
  - Edit current connection (wlan0 in my case)
  - Go to IPv4 settings
  - Select DHCP (addresses only)
  - Set a DNS server, say (it's the first server from OpenNIC project)
  - Click save
  - Click disconnect
  - Click connect

  In the summary, you can see the DNS server you just typed. But if you
  # cat /etc/resolv.conf
  then you see the DNS server provided by your DHCP server (in my case

  So the only way to bypass DHCP's DNS settings is to hard-code the DNS
  in /etc/resolvconf/resolv.conf.d/head

  Since this can lead users to believe that they are using their
  favorite DNS server while they get answers from their ISP/Hotspot DNS,
  I checked the 'Security' box.
