c - How to open a non-decorated fullscreen window on Ubuntu -

what trick open non-decorated fullscreen window on ubuntu? used alter _net_wm_state property _net_wm_state_fullscreen accomplish while working fine on kde doesn't seem work on ubuntu (gnome; tested 12.04 lts). launcher on left , title bar still there , appear above non-decorated fullscreen window not want.

when switching fullscreen mode in firefox, however, firefox's fullscreen window covers finish screen including launcher panel , title bar must possible somehow open windows cover entire screen, including ubuntu's launcher , title bar.

could explain how accomplish behaviour using plain x11 without middleware?

thanks!

i've found problem. setting _net_wm_state_fullscreen not enough. 1 should set override_redirect attribute true prevent window manager intercepting configure , map requests seems gnome doing on ubuntu putting launcher panel , title bar on fullscreen window. setting override_redirect true prevents this.

c unix x11 xlib
