Where does bitcoin-qt store it's initial settings I installed bitcoin-qt (v 0.12.1) on Kubuntu 15.10. When starting it the first time the GUI asked me for the datadir. I set it to an external disk.

Where are this settings stored? There is no bitcoin.conf file in my /home/&lt;user&gt;/.bitcoin/ directory.

I know, that I can manually create the bitcoin.conf file. But I'm just curious, where the settings are stored, if no such file is present?
Bitcoin-Qt stores its own modifiable settings outside of bitcoin.conf (which is intended to only be read).

The location and format of that file is platform dependent, but on Linux it is ~/.config/Bitcoin/Bitcoin-Qt.conf.
