Font hinting on Linux

[quizynox at gmail.com]

Hello,

Sorry for asking here, but I seem to have tried everything I could find 
on SO/Reddit/JBS etc. Could someone please share what font settings I 
should be using to get decent font hinting on Linux? Please see the 
screenshot.

I'm not very picky, but the font I see is just not suitable for 
presenting app to customers. I've tried enabling and disabling hinting 
and autohinting, using different hinting styles, changing the font 
smoothing type and prism.lcdtext etc. Unfortunately no matter what I do, 
the font hinting is always bad.

Fedora, KDE, all latest versions.
