I have a window in Gnome whose titlebar I would like to remove. This was easy in FVWM2: I just set the window style to include NoTitle. In Gnome there does not appear to be a similar option.
I recently learned to use wmctrl to modify EWMH-compliant window options, but it also has no method to remove the titlebar (that I can see).
There must be some way to do this, however, because applications like Audacious can tell Gnome not to display window decorations.
Googling, I found some pages that discuss the issue of removing the titlebar with wmctrl, but in each case the solution was simply to fullscreen the window, such that the titlebar moved off the screen altogether. (That's not what I'm looking for!)
Thanks for any help.
It occurred to me to try Googling for hide 'window decorations' instead of titlebar, and I believe I've found some more options.
Specifically, the Window Decoration section of the CompizConfig Settings Manager allows one to specify rules for displaying decorations, which includes the titlebar.
I still think there's no way to perform this modification using plain vanilla Gnome (and I haven't looked into wmctrl any further), but since the only reason I'm using Gnome in the first place is the easy integration of Compiz, this solution works for me.
