The Debian Installer doesn't have support for ZFS at all, so it's use to 
rescue for root-on-ZFS systems is limited, at best, regardless of the 
encryption.

Re: Capture d'écran avec wmctrl+import

[Pierre ESTREM]

Bonjour Etienne et le monde libre,

Exact ainsi ça devrait passer.
Ca explique pourquoi "import -window root image.png" fonctionne (la 
capture ne se fait que sur la fenêtre principale).


Il faut que j'adapte ton algorithme  à ma sauce.

Un truc que je ne comprends pas est que "wmctrl -d" ne me renvoie qu'UN 
desktop, alors que j'en attendais 4...


Merci

Où est mon erreur ?

C'est une limitation de "import", le programme ne prend pas en
charge la capture des fenêtres qui ne sont pas rendues à
l'écran.  Une manière de contourner ça serait de rapatrier la
fenêtre sur le bureau courant, le temps de la capture, puis de
la renvoyer à son bureau d'origine, une fois que c'est fini.
Aux fautes de frappe près, ça donnerait un script du genre :

#! /bin/sh
# Identification du firefox
window="$(wmctrl -l | grep -i firefox | cut -f1 -d" ")"
orig_desktop="$(wmctrl -l | grep -i firefox | cut -f3 -d" ")"
# Bureau en cours d'utilisation
cur_desktop="$(wmctrl -d | grep ' \+\* DG: ' | cut -f1 -d" ")"
# Transfert du firefox sur le bureau courant
wmctrl -i -r "$window" -t "$cur_desktop"
# Capture de la fenêtre du firefox
import -window "$window" screenshot.png
# Renvoi du firefox à son emplacement d'origine
wmctrl -i -r "$window" -t "$orig_desktop"
# Fin

D'après mes tests, la fenêtre du navigateur ne vole pas le focus
pendant la manœuvre, donc il ne devrait pas y avoir trop
d'interférences de ce côté là.  Le script n'est pas encore au
top niveau : si le firefox est iconifié, alors l'import va tout
de même planter, mais je crois que l'option -b de wmctrl
permettrait de faire les ajustements nécessaires, s'il y a
besoin de traiter ce cas de figure plus en détail.

Bonne soirée,  :)

I would probably rather start with the existing scummvm package in the

It is passed by dh_auto_configure, see
/usr/share/perl5/Debian/Debhelper/Buildsystem/autoconf.pm.

That is what the Debian package does[1], because scummvm's configure
script is apparently not produced by autoconf.

Building a package for ScummVM 2.5.0

[Christian Britz]

Hello,

I am trying to build a Debian package for the latest ScummVM release for 
personal use and need help.
I have no deep knowledge of Debian packaging, but in the past I had some 
success with applying dh_make to source trees.


This is what I have done in the source folder:

dh_make -n -s -e a...@bbb.ccc
fakeroot debian/rules binary

Output:

dh binary
   dh_update_autotools_config
   dh_autoreconf
   dh_auto_configure
    ./configure --build=x86_64-linux-gnu --prefix=/usr 
--includedir=\${prefix}/include --mandir=\${prefix}/share/man 
--infodir=\${prefix}/share/info --sysconfdir=/etc --localstatedir=/var 
--disable-option-checking --disable-silent-rules 
--libdir=\${prefix}/lib/x86_64-linux-gnu --runstatedir=/run 
--disable-maintainer-mode --disable-dependency-tracking

Running ScummVM configure...
error: unrecognized option: --disable-option-checking
[...]

The configure script seems to be unable to deal with the parameter 
--disable-option-checking. Where is this set? The debian sub directory 
does not contain that string.


Running ./configure manually works fine.

I also played with the checkinstall tool without success, it seems to be 
irritated by faulty git files.

Christian

In installations using systemd, targets have replaced runlevels. Selected 
runlevel
numbers are aliased to selected targets. e.g. 3 equates roughly to
multi-user.target, and 5 equates to graphical.target, when used on a kernel
command line or the telinit alias to systemctl:

# ll /sbin/init
lrwxrwxrwx 1 root root 20 Jul 13 13:29 /sbin/init -> /lib/systemd/systemd
# ll /sbin/telinit
lrwxrwxrwx 1 root root 14 Jul 13 13:29 /sbin/telinit -> /bin/systemctl

Bonsoir,

Ben non, ça ne passe pas.
Pourquoi compliquer avec 'awk' ?
Un bon vieux 'cut' fait l'affaire.

L'ID de la fenêtre s'obtient aussi facilement :

Et c'est la commande dessous qui échoue :

Bonjour Pierre,


Pourrais-tu simplement essayer de corriger ton script du fait que tu as
2 occurrences qui se marchent dessus et je suis en train de déverminer ton
script  


En premier je fais un essai pour trouver firefox :

wmctrl -l |grep -i -w  "firefox"

j'obtiens un premier résultat convenable :

0x0480002c  4 antigen 16 exemples de commandes grep pour vous aider dans le 
monde réel - Mozilla Firefox

je continue de vérifier ton script :

wmctrl -l |grep -i -w  "firefox" | cut -f1


j'obtiens :

0x0480002c  4 antigen Zimbra: Répondre - Mozilla Firefox

Je reprends ton script à la base en évitant les erreurs :

wmctrl -l |grep -i -w  "firefox" |awk '{print $1}' |tail -1


et le résultat donne le PID de Firefox :
0x0480002c


Pourrais-tu essayer la commande ?

Ensuite, je t'invite à relire le fil de discussion concernant
tesseract et les documents PDF images qui doivent impérativement
être convertis au format Tiff et non au format png ...

window="$(wmctrl -l |grep -i -w  "firefox" |awk '{print $1}' |tail -1)"
  
import -window "$window" screenshot.png



en tout cas maintenant, c'est opérationnel pour obtenir une image png
maintenant, il te faudra convertir l'image png au format tiff :

convert screenshot.png screenshot.tiff


pour ma part je n'aime pas du tout cette façon de faire du fait qu'il me manque
un point qui peux devenir gênant en en donnant pas un "timestamp" de la capture
dans le nom du fichier

correction :
import -window "$window" screenshot-$(date +%Y-%m-%d-%H-%M).png
convert screenshot*.png  screenshot*.tiff


après il te suffira de passer à la moulinette via tesseract

Merci pour ton aimable attention

Bien à toi

Bernard

What version of Debian are you running?  (cat /etc/debian_version)

What init system are you using?  (ls -l /sbin/init)

If you're using systemd, be aware that the /etc/inittab file is not
used.  It's used by sysvinit.

I don't know what a CTRL+F3 console is, and googling this only hints
that it might be   /xfwm4/custom/F3 workspace_3_key   and
/xfwm4/default/F3 workspace_3_key, whatever that is.

So my first step would be to find out what process it is that you're
typing into when all this occurs.

Ditto.

Ditto, and what's asking for a password with apt-get?

Pinning down the exact process might not be straightforward or
particularly productive. My own attempt (an asterisk occurrence) was
fairly fruitless as the answer appeared to be udisksctl, which under
other circumstances emits no asterisks.

I have a serious problem with this example: it doesn't show what happens
when the number of digits changes.  What if the first (oldest) directory
were number 99 instead of 100?  Would it be named "99", or would it be
named "099"?  When you get to directory number 1000, is there going to
be another change in the number of digits?

Because of this ambiguity, we have to assume the *worst* case, which is
that the number of digits changes over time.  The directory names will
be "99", "1000", and so on.  Not a fixed length.

Why does this matter?  Because when you list the directory names and sort
them by name, you will get a mangled sequence:

unicorn:~$ mkdir /tmp/x && cd "$_"
unicorn:/tmp/x$ mkdir 98 99 100 101 102 103 104
unicorn:/tmp/x$ echo *
100 101 102 103 104 98 99

The names are sorted lexicographically, not numerically.  So, the simplest
approaches are NOT permitted.  They will fail.

What does that leave?  Well, the more complicated approaches, of course.

If we believe Gokan's assertion that the directory names will always be
strictly numeric, or the word "last", then we can use "sort -n" to get
them in sequence.

unicorn:/tmp/x$ printf '%s\n' * | sort -n
98
99
100
101
102
103
104

>From there, it becomes pretty straightforward.  We read these names into
an array, and process all except the last 4.

Here's one way to do that:

unicorn:/tmp/x$ mapfile -t dirs < <(printf '%s\n' * | sort -n)
unicorn:/tmp/x$ n=${#dirs[@]}
unicorn:/tmp/x$ echo "${dirs[@]:0:n-4}"
98 99 100

The dirs array holds all of the names.  We count how many there are, and
then process "all but 4" of them, starting from element 0.  In my example,
there are 7 directory names, so we process 3 of them.

We also want to avoid processing "last", so we probably want a glob other
than * for our input.  We could get fancy and use an extended glob like
!(last) -- or we could simply use [0-9]* to match only the names that
begin with a digit.  In the interest of simplicity, let's do the second
thing.

So, the script might look something like this:


#!/bin/bash
cd /wherever || exit 1
mapfile -t dirs < <(printf '%s\n' [0-9]* | sort -n)
n=${#dirs[@]}
echo rm -rf "${dirs[@]:0:n-4}"


This will *print* a command instead of running it.  If you test it and
see that the command looks sensible, then change "echo rm" to "rm" and
voila.

You could "find" the directories concerned, "sort" by some criteria
(name, or time etc), use "head --lines=-5" to drop the last five lines,
and "rmdir/rm" to remove any remaining in the list.

For fewer processes, you could do a similar set of operations in
shell by constructing an array, removing five elements, and using
any remaining elements to remove the directories (and their contained
files) in the same manner.

Remember to deal with the symlink in whatever manner you choose
(check it, ignore it, etc).

Before I actually used either method, I would test it with "echo"
or "mv -i" rather than removing anything, and before I attempted
the latter, I would refresh my recollections of these pages:

https://mywiki.wooledge.org/BashGuide/Arrays
https://www.tldp.org/LDP/abs/html/arrays.html

BTW your Subject line implies the opposite.

Hi Ibrahim,

Are you subscribed to the list?

I ask only because you asked this on the 6th and got some replies -
look at the thread from 
https://lists.debian.org/debian-user/2021/10/msg00282.html onwards

At this point, Jessie is supported only by the people running ELTS.

You might want to look at https://wiki.debian.org/LTS/Extended and then
contact Freexian who might be able to help. https://www.freexian.com/

Other than that: upgrade and move forwards in time, perhaps.

All the very best, as ever,

He/she might even try to just login into ldap, from the post

Hi,

I run Bullseye and I find it very solid and trouble free. Though I didn't 
upgrade from Buster but instead used to run unstable and switched to stable 
when it released. Bullseye's KDE is very good and I have no issues with it 
other than I don't recommend you to run a Wayland session of it, you should 
stick with X11 for the time being. There exists unofficial repositories by a 
Debian/KDE packager if you wish to get more recent KDE software releases built 
for Bullseye.

Yes, I would never consider running a public web server, I know just
enough about web security to know that I don't know anything like
enough to keep it secure. 

But I don't expose the IMAP server, either, it's internal only. I get
to it by ssh or vpn while away from home. It's less convenient, but
less to worry about.

Ondertussen heb ik het zelfde probleem ook voorgehad. Vreemd.

Ik heb wat terug opgezocht, en dan gevonden dat die "MultiProfile"
setting daar inderdaad voor was -- maar dat werkt dus niet bij iedereen.

In mijn geval leek het opgelost te raken door pulseaudio te herstarten
als mijn headset verbonden was:

systemctl --user restart pulseaudio.service

I wasn't aware of any kind of support for ZFS in d-i.

The Debian ZFS wiki page doesn't mention root-on-ZFS at all and the 
official upstream instructions (for buster) are using debootstrap from a 
live image for installation.
