Linux – How to edit the main menu

You will need to copy the theme from "/usr/share/themes/themename/gtkrc" to $HOME/.config/gtk-2.0/gtkrc and modify it. Please see xfwm4 theme guide on the xfce wiki.

(1) Shadow,

Text shadow

A shadow can be added to the title text by setting the boolean value “title_shadow_active” for the focused window, and “title_shadow_inactive” for the other unfocused windows.

Possible values are “false”, “true”, and “frame”.

(2) Titelbar decorations,

For title bar decorations, xfwm4 uses 5 pixmaps named title-1-active.xpm to title-5-active.xpm with top-left-active.xpm and top-right-active.xpm making up the corners on each end as per figure 2 below.

You have to edit as a root /usr/share/mint-configuration-xfce/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml and comment out or delete this tag:

<property name="Super_L" type="string" value="xfce4-popup-whiskermenu"/>

Then logout and login.
