179043 - Fullscreen does not work anymore in most window managers

Status: RESOLVED WORKSFORME

(SeaMonkey :: UI Design, defect)

Description

[Olli Pettay [:smaug][[e-mail]]]

When entering fullscreen mode, the chrome changes to the 
right one, but window titlebar and borders remain visible and
the window is not even maximazed.

This used to work fine. 
Maybe a regresssion of Bug 176640?  

Using Moz2002110721trunk

Confirming the regression. F11 to trigger fullscreen now changes window chrome,
but not window size.

Comment 2

[Olli Pettay [:smaug][[e-mail]]]

The fullscreen works with moz20021105.
Bug 176640 was checked in 20021106,
and moz20021107 does not work.

We might want to check what version of the WM spec the WM supports and use the
correct method accordingly.

... or disable fullscreen mode entirely if it doesn't support the fullscreen
hint (this is what hp suggests in
http://bugzilla.mozilla.org/show_bug.cgi?id=126685#c85 )

You don't want to check version, just check if _NET_WM_STATE_FULLSCREEN is
supported, as with gdk_net_wm_supports()

So, I think this bug is INVALID (since it's not up to us to fix it -- KDE needs
to implement this hint in the window manager).  I filed bug 180863 for this.

But fullscreen used to work well enough in KDE and most (or at least many)
Linux users use KDE.
So I'd rather have "an almost working fullscreen mode", than
a mode which work perfectly in Gnome2 (Bug 176640), but not in KDE.

Actually, it's not just KDE. This bug also applies to Window Maker, fvwm2, and
even Gnome 1.4 with Sawfish window manager. And probably many others.

So, it would seem like fullscreen mode is now broken everywhere except Gnome2
with Metacity...

It should work with any WM that implements the new specs.
WMs that generally track the EWMH spec include 
fvwm2, kwin, blackbox/openbox, icewm, sawfish, metacity, at minimum.
I'd expect latest versions of most of those to have fullscreen mode 
or to add it shortly.

Before adding _NET_WM_STATE_FULLSCREEN to the spec it was 
basically impossible to implement a reasonable fullscreen mode
on X (it's going to be inherently somewhat buggy/broken in the 
absence of that hint), so disabling it makes sense to me.
Otherwise the mozilla developers will get a continuous stream 
of bug reports about basically unfixable little problems with 
the mode.

You should be able to download/install a new WM version as easily as you can
download/install a new Mozilla version.

-> bryner for a look

[Nick Blievers]

This occurs on OS's other than Linux (IRIX for eg), and it did used to work.
If its not going to be fixed for all Window managers (eg ones with out
_NET_WM_STATE_FULLSCREEN), then the option should be removed or grey'd out. 
Otherwise you get a very wierd response (eg the fullscreen UI without any change
in window size).

Comment 15

[Gabriel Baines]

If it's not going to be fixed in Mozilla, could someone with a solid
understanding of the problem be so kind to file a bug against KWin in KDE's
Bugzilla?

Or maybe the problem has already been reported as
http://bugs.kde.org/show_bug.cgi?id=42911 ?

Thanks.

I can use full-screen mode under IceWM.  Is it time to close this bug?

Comment 17

[Rolf Leggewie]

no further comments, somebody please close this bug.

[Lorenzo Colitti]

Marking WFM based on lack of activity. If someone still sees this with a recent WM, please reopen.
