Ubuntu – How to hide Firefox titlebar in Gnome Shell

Session saving was removed during the development of Natty, so presumably, it's not in Oneiric either.

Here is a notice on what we decided during the Rally: we drop session saving from natty in Ubuntu. The disablement is already effective in natty.

== Why removing it? ==

We saw a lot of side effects during the previous cycles when we started to use multiples session (like in UNE, desktop session and such): - the saved applications contains the list of all running application, including the window manager, the panel and such… Consequently, we got a lot of patches and hack to avoid saving mutter, compiz, metacity, and the panels in lucid and maverick, so that when someone wanted to start a session, the required components from the session will indeed been launched instead of the saved one. - We tried last week to change the desktop order but it went quite wrong with a lot of settings and we had to revert it. - In addition to that, session saving never really worked with all the default applications we have (for instance, openoffice, firefox…) and even with supported applications like gedit: the opened documents weren't started again, making the feature quite useless.

The information above was derived from this source (visit this link for the full details): http://www.linux-archive.org/ubuntu-desktop/478109-gnome-session-saving-dropped-natty.html

Maybe you could suspend your computer instead of logging out? I believe that "saves" your session as well, as everything is there when you bring your computer back from being suspended.

This was achieved using devilspie to start darktable maximised, followed by my linked answer to remove the window decoration.

Note - I tried this with the devilspie "undecorate" command but that just left an annoying blank space where the decoration would be

install devilspie

sudo apt-get install devilspie
mkdir ~/.devilspie
nano ~/.devilspie/darktable.ds

copy and paste the following:

  (is (application_name) "darktable")
    (begin
       (maximize)
       (spawn_sync "/home/dad/decoration.py")
       (spawn_sync "/home/dad/decoration.py")
    )

N.B. substitute /home/dad/decoration.py for the full-pathname to the undecorate script. Save.

Finally, make sure devilspie start in your startup-applications.
