Where Does Qt5ct Store Config on Linux?
Qt5ct config file with colorschemes and stylesheet folders on Linux.
Last updated
Qt5ct centers on one conf file under XDG config. Colorschemes and stylesheets branch into their own folders beside it. Local share mirrors both for good measure.
System trees provide packaged themes with an etc fallback default. User copies shadow everything. That layering keeps distro updates from clobbering custom looks.
Where Qt5ct stores this, by platform
~/.config/qt5ct/qt5ct.conf
Main conf under XDG with colors and qss subfolders. Local share mirrors both. System share trees plus etc fallback default. User copies shadow packaged themes.
Frequently asked questions
How do I back up Qt5ct?
Copy the qt5ct config folder with no Qt apps running. Colors and stylesheets travel inside it. Restoring means putting the folder back before launching apps.
How do theme lookups resolve?
User folders win in order: config colors, local share colors, then system share trees. Stylesheets follow the same waterfall under qss folders. System etc holds the fallback default.
