gtkqtthemes
When I start any Qt app, I get this message in the terminal, and the Qt app doesn't use the same theme as my Gtk apps:
QGtkStyle was unable to detect the current GTK+ theme.
How do I make QGtkStyle detect my current GTK+ theme?
It seems that LXDE is using a settings daemon, and there is no gtkrc-2.0 file in my home folder.
Want to edit the desktop colors? No graphic way to do it in Ubuntu 11.10/12.04.
gksudo gedit /usr/share/themes/Ambiance/gtk-2.0/gtkrcselected_bg_color. Feel free to change the other colors using HTML colors.This should set the background color for Chrome/Chromium.
