lock screen before hibernate

English Applications
1

First off I’m using gnome 3 and opensuse 12.2 on my laptop (not my desktop signature). I have Ubuntu, opensuse, windows 8 beta, and Kubuntu on it.
I wanted multi-hibernate my laptop so I switched my swap from my swap partition (/dev/sda5) to a file on /dev/sda6. I changed my /etc/fstab, I then changed my grub2 statement
to
resume=/dev/sda6 resume_offset=whatever running swap-offset myfile was
Then I noticed hibernate button doesn’t work
so I switched to the kernel method and wrote a script

#!/bin/bash
echo shutdown > /sys/power/disk
echo disk > /sys/power/state

Then I made a keyboard shortcut to F11
gnomesu my_hibernate_script

Works very nicely
but my screen won’t lock b4 it shutsdown
I’ve tried editing my script to include:

su <myname> -c gnome-screensaver-command --lock &

all combinations of such
to no avail

so my question is if its possible to lock it b4, whether there is some other place to signify this

and what do you think about my hibernate setup anyway. AFAIK the kernel method is the only way to hibernate to a swap file, if not can you point me in the right direction
(pm-utils etc). Would be nice if I could use the already made button under the menu for powering down/logout.

Thanks for any help

hopefully you are not running GNOME as root, right?

so, when you are running GNOME as yourself and want to manually lock the
screen, do you have to do that as root, or can’t you do it as yourself?
(i ask because i’ve never seen GNOME3 running, so i have no idea if
‘they’ made it so that a simple users can’t lock their own screen–but i
doubt it)…

well, if you can lock your GNOME screen, then i see no need to provoke
“su” in a script to do the same thing (wouldn’t doing so tell the system
to lock root’s screen–when he shouldn’t even have a screen to lock!!)…

so, also think about maybe you should lock your screen in a script owned
and located in your /home and executed by you, which then (somehow)
launches the next phase of your hibernate sequence…which probably does
need root powers.

and, if you do it that way for all your various linux distros: each user
could invoke the correct way to lock their screen and then hand off
the hibernating task to each distro’s unique way of doing that (do NOT
assume that all linux distributions will react the same way to the same
script:

If you have seen one Linux, you have seen one Linux.

and, for next time: in my opinion your post, and especially this
question “and what do you think about my hibernate setup” should be in
our programming & scripting forum, here: http://tinyurl.com/5v695w4

[that is where the scripting gurus seek such questions…they might not
ever look into your thread in the applications forum–hmmmm, is
‘hibernate’ an application?]

anyway, if sudoers were so set, wouldn’t it be “sudo <myname> …”

well thanks for pointing me in the direction of scripting and programming forum. I thought maybe the gnome interface and such would constitute an application, but I’ve been wrong before. What I really want is to use pm-utils , so I can use the hibernate button, but I don’t believe it works with a swap FILE.

wellllll…perhaps i missed the main thrust of your thread when i
decided you ‘just’ needed help to perfect the script which would lock
the screen prior to hibernate (as in the subject line) i now see that
was probably not what you really needed…that is, perhaps the script is
not the thing here to be ‘fixed’…maybe it is your entire approach to
the problem, and yes maybe you need a gnome guru to point the best route
(and not a script guru)…

having last run gnome (on Red Hat) last century, and i’m not a script
guru either…so, i’m sorry i made any posts in this thread at all.

i guess Malcolm Lewis might have a trick to make you smile…
