I have Kubuntu 12.04 (KDE 4.8.4). I also have
ubuntu-desktop installed. I am using the Oxygen, which I like very much except for the scrollbars. I have written a scrollbar theme (based on Gmail scrollbar theme for Firefox). How can I make sure that every window uses my scrollbar theme instead of Oxygen's? I found some CSS files in
/usr/share/themes/oxygen-gtk/gtk-3.0/. Is there something I can edit there?
My scrollbar theme can be found here, if anyone is interested.
