I installed Ubuntu with several Desktop Environments, including Unity, KDE and LXDE.
I am struggling to change the background tooltip color which is black and causes displaying problems in Eclipse.
I managed to do this in Unity as explained here: How to change tooltip background color in Unity?
I was unable to do this in LXDE. However when I changed the tooltip background color from KDE GUI settings (System Settings -> Application Appearance -> Colors), the change was also reflected in LXDE, so I assume there must be a configuration file from which all desktop environments read this information.
Where are theme settings stored?
