Re: X launch hijack?

I previously wrote in this thread:

The other thing I don't understand is why you need to do that at
all.  X11 programs are entirely capable of having their window be
full-screen size even after a standard xinit/startx startup, so I
would think you wouldn't need to do a special startup to get
full-screen, unless that's an openttd issue.

to which Louis Epstein <le@lekno.ws> replied:

The issue may be with my .xinitrc invoking the window manager,
apparently that was not there before (AND I used a different
window manager).

I replied:

I'd be surprised if it has anything to do with .xinitrc, but not
surprised if some window manager has an always-on-top bar of some
kind.  twm, for example, does not.  As Gerhard indicated, window
managers that have tool bars may also have a way of getting rid of
it, or at least of disabling its always-on-top property.

Louis replied:

I used fvwm2 before and this time it's xfce4.

A Google search turned up the following regarding xfce4, which you could
try:

How do I hide the top bar in xfce4?

   Right click on the terminal, select preferences.  You'll be on the
   "General" tab: Lots of features here, including eliminating the
   scrollbar.  If you click on the "Appearance" tab, in the section
   "Opening New Windows" you can select whether or not to see the
   menubar, the toolbar or the borders.

It looks like that answer comes from
        https://forum.xfce.org/viewtopic.php?id=13350
which discusses the issue in connection with xfce4-terminal.  There's
also a suggestion that "--maximize --hide-menubar --hide-borders" might
do what you want.

If that doesn't work, while reading, I got the impression that one can
have multiple panels, that different panels can have different
properties, and thus that you might be able to create a second desktop
panel that has no toolbar that you could switch to when you want that.

HTH, but I don't know xfce,
