#261610 — automate resumption of session

I am a writer.  I use Emacs and LaTeX markup on a Debian/XFCE system.
On a typical day, I have in progress three or four articles.  I may
work for several days on a given article.

Each article is in a separate XFCE workspace.  The text for each
article resides in its own directory.  For each article, I keep open
an instance of emacs, a terminal window from which I execute latex and
xdvi, and the xdvi window.

When I leave the office for the day, I typically shut down the
computer.  The next morning, the first order of business is to
recreate the previous working environment or ``session.''  For each
article, this entails:

(1) Click on the appropriate workspace button.

(2) Open an instance of emacs.

(3) In the emacs window, use the mouse to click on the icon to resize
the window.

(4) In emacs, open the file in the document directory.

(5) Open a terminal window.

(6) In the terminal window, use the mouse to click on the icon to
resize the window.

(7) In the terminal, cd to the document directory.

(8) In the terminal, execute ``xdiv ... &'' to display the document.

I would like write a script to automate the process, so that I need
only boot the computer and type RESUME; but my efforts have been
unsuccessful.

I wish I had that option.  But I live way out in the country, and now
and then there is a power outage.  My computer is running on a UPS,
but UPS batteries die after being run down more than a few times, and
battery replacement is expensive.  And then there are lightning
storms...

Same here, I always just suspend.

For those computers where I'm not coming back to them the next day,
I hibernate them, so they're truly "off" and a powercut is perfectly
harmless, but when I turn them back on I get back to where I was.

I have been using Debian since A.D.2000, but I never have been clear
on the use of suspend and hibernate.  If I am going to power-down the
computer, hibernate sounds good; but how do I resume?

Reboot as you always do. Hibernate uses swap space to preserve portions
of RAM. As the system boots, it will examine the swap space and read
the data back into RAM.

You may wish to reboot from time to time. I observe some of my laptops
get crankier the more I hibernate them.

Don't do that. Open one instance of emacs, then use multiple frames,
one (or more) on each workspace. C-x 5 2. C-x 5 0 to close one. Even
today emacs is a resource hog. You can then open all the files you
want, in multiple frames or multiple windows within each frame. Also, I
suspect that the next step won't work with multiple instances of emacs,
without some serious and quite unnecessary finagling.

Now, to preserve all that across sessions, use emacs' desktop mode.
https://www.gnu.org/software/emacs/manual/html_node/emacs/Saving-Emacs-Sessions.html,
https://www.emacswiki.org/emacs?action=browse;oldid=DeskTop;id=Desktop
You may have to manually save emacs' desktop once, but after that emacs
will save the desktop for you on exit, and restore it on launch.

Those two changes should get rid of a lot of your morning routine.

For the rest, look at XFCE's ability to save sessions. Applications ->
Settings -> Sessions and Startup. For example, preserving XFCE
terminals includes preserving the working directory.

Also recall that Bash (and most other shells) reserve a history of
previously used commands. Instead of typing, e.g.,

vlc ~/Music/playlist.m3u &

I find it much simpler to type

^Rvlc

or some such.

Noted and now being implemented.  Many thanks, Charles.

If hibernation can work reliably on your system it would seem to meet
your requirement.

FWIW, hibernation should usually work "on any system".

Usually if it doesn't work it's because the system's boot setup doesn't
accommodate it rather than because the hardware (or Linux) doesn't
support it.

The more common way to make it work relies on using a swap partition,
and an initramfs boot step that is able to find that swap partition, for
example.

Don't close/exit your running applications on the XFCE desktop, leave
them open/running and choose "Shutdown" from the XFCE exit dialogue.

On next login in to the XFCE desktop, XFCE will start all applications,
which have been open at reboot/shutdown time. Works for me with Debian
Bullseye/XFCE. Just try and test it with Bookworm/XFCE.
