To make the Xfce Window Buttons applet (or simply the Taskbar, as all of us are used to call it) multi-row, add the following to ~/.config/xfce4/gtkrc (create the file if it doesn’t exist):
include "/usr/share/themes/greybird/gtk-2.0/gtkrc" # Change 'greybird' to whatever Xfce theme you're using style "xfce-tasklist-style" { XfceTasklist::max-button-length = 192 XfceTasklist::max-button-size = 16 # Make sure that this value is at least two times less than the panel size XfceTasklist::ellipsize-mode = PANGO_ELLIPSIZE_END XfceTasklist::minimized-icon-lucency = 50 XfceTasklist::menu-max-width-chars = 24 } class "XfceTasklist" style "xfce-tasklist-style"
After you relogin, your panel should look like this
