For Chrome 44 and higher:

chrome://flags/#enable-new-profile-management no longer works, and probably won't be fixed in future too. But there is workaround:

If you want a temporary solutions (that works only for a 'session', you can start chrome from terminal with the --disable-new-avatar-menu flag as in:

google-chrome --disable-new-avatar-menu

If you want a permanent solution:

1. Edit your Chrome .desktop and add the parameter --disable-new-avatar-menu. So:

   
   
   

   sudo nano /usr/share/applications/google-chrome.desktop
   
   

   
   
   

   and edit the Exec line as follows:

   
   
   

   Exec=/usr/bin/google-chrome-stable --disable-new-avatar-menu %U
   
   

   
   
   

   My .desktop file for chrome looks like this:

   
   
   

   [Desktop Entry]
   
   Version=1.0
   
   Name=Google Chrome
   
   GenericName=Web Browser
   
   Comment=Access the Internet
   
   Exec=/usr/bin/google-chrome-stable --disable-new-avatar-menu %U
   
   Terminal=false
   
   Icon=google-chrome
   
   Type=Application
   
   Categories=Network;WebBrowser;
   
   MimeType=text/html;text/xml;application/xhtml_xml;image/webp;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/$
   
   X-Ayatana-Desktop-Shortcuts=NewWindow;NewIncognito
   
   
   
   [NewWindow Shortcut Group]
   
   Name=New Window
   
   Exec=/usr/bin/google-chrome-stable
   
   TargetEnvironment=Unity
   
   
   
   [NewIncognito Shortcut Group]
   
   Name=New Incognito Window
   
   Exec=/usr/bin/google-chrome-stable --incognito
   
   TargetEnvironment=Unity
   
   




2. Restart Chrome

   
   
   

   

For Chrome 43 and lower:

1. Copy/paste the following into the omnibox: chrome://flags/#enable-new-avatar-menu


2. Set the value to "Disabled"


3. Restart Chrome
