Is there a way to recover data from un-allocated space? I can send any kind of 
log if required.

Any kind of disk\partition manipulations should begin with data backup, 
but I think you've figured that by now.


In order to recover any data you should first stop using this HDD (don't 
mount it as writable) and get yourself another HDD with suitable size, 
that will serve as destination for recovered data.
You'll have to remove HDD from your notebook and connect it to a PC with 
standard SATA cable along with destination HDD.
With that setup, you have to use R-Studio software (They have free 
version for Linux partitions, IFAIK) to scan source HDD for traces of 
partition table and LBA offset of partition that was "sda8".
If R-Studio will manage to find right offset and recognize filesystem 
then you will be able to start automatic scan for files available for 
full or partial recovery.

Success is solely depends on how destructive was HP system recovery process.

Depending on how valuable your data was you probably will have to resort 
to professional data recovery services, which will do roughly the same 
procedures as I described above and charge substantial amounts of money 
for it.
Since you won't write anything to your source HDD and it is not 
mechanically failing, it is safe to try to recover data by yourself first.
This is a slightly different case, but another tool I found quite 
effective in recovering data from a failing hard disk was ddrescue:

https://packages.debian.org/stretch/gddrescue
You might want to have a look at it.

Maybe this will be a useful clue:

In Stretch, any gettys running on vtty[1-6] are actually agettys.
Files in /etc/systemd/system/getty.target.wants/ are symlinks to:
/lib/systemd/system/getty@service
# ps -A | grep get
 1021 tty3 00:00:00 agetty
 1022 tty4 00:00:00 agetty
 1023 tty2 00:00:00 agetty
 1451 tty1 00:00:00 agetty
 3932 tty6 00:00:00 agetty
12733 tty5 00:00:00 agetty

Why all this would tie up the serial port I don't know.

Re: What is agetty, and why can't it be stopped?

[Miles Fidelman]

agetty is "alternatative getty" - it's the terminal driver that listens 
on each terminal port


it's launched by init (or systemd), most likely in respawn mode - you'll 
need to find the init file (or systemd equivalent) that launches it, and 
change the config


do a "man getty" or "man agetty" and you should find what you need

I use a USB microscope brand name Andonstar, recently bought online.

It works fine in Debian, where it behaves just like a webcam.
The video output appears in cheese, but it is laggy, so I prefer

There is one serious disadvantage: Firefox doesn't support audio

If you don't care about that, then you can certainly play music,
record audio, and otherwise do normal audio-related things
through ALSA.

I got shot of PulseAudio more than a year ago because of serious sound
latency issues (700-1200+ms in VirtualBox/WinXP for some old games I
love).  Using plain ALSA fixed that.

I had already switched to Palemoon as a browser (other problems with
Firefox - not audio relevant) at that point, and now also use Waterfox,
and have not missed PulseAudio or Firefox at all.  As I type this, I am
listening to Saint-Saëns Symphony No 3 on YouTube using Waterfox with no
problems whatsoever.

I don't know of any other desktop applications that actually need
PulseAudio and can't think of any disadvantage(s) to removing it.

Excellent!  :)

Sorry for not having replied a bit sooner, I was still trying to
make sense of the situation.  I confirm the OpenGL library is
made available in my Stretch boxe in version 1.2.0:

$ dpkg -S /usr/lib/i386-linux-gnu/libGL.so.1.2.0
libgl1-mesa-glx:i386: /usr/lib/i386-linux-gnu/libGL.so.1.2.0

Also, if I may add, you wrote:

True, it is not needed.  I guess it may even be unwelcome on CNC.

Re: OpenGL forwarding via ssh session: works on jessie, does not work on stretch

[Simon S]

I think i found the culprit:

I use the debian apt repo for machinekit and the rt kernel:
deb [arch=armhf] http://repos.rcn-ee.com/debian/ stretch main

This repo installs libGL.so.1.0.0 instead of libGL.so.1.2.0.
I forced to use the default debian apt source repo and purged all libgl stuff 
from the rcnee repo.

And now i get: 
> glxinfo|head
name of display: localhost:10.0
display: localhost:10  screen: 0
direct rendering: No (LIBGL_ALWAYS_INDIRECT set)
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4

perfect!

So it seems like the libGL package is somehow messed up or not up to date on 
the repo server I use because of the machinekit stuff.

I contacted the owner of the repo and I will wait for his reply.

Maybe so.  But why doesn't it query the printer for its abilities instead 
of defaulting to the lowest common denominator settings which are 
apparently not adjustable?

Then give us a configuration utility that works when I tell geany to 
print something. I have 3 different configs for that printer, one for 
single sided photo on glossy paper from tray 1, one for duplex on copy 
paper from tray 2, and one for hand fed 11x17 paper.  Yes, this 
MFC-J6920-DW is a bigger than your average bear printer.  And after 3 
years of living with it I do know how to run it.

Your choice. I can't afford the tickets to get there anyway.  If it has 
to be configured before use, where is the help to guide one to do it 
correctly? I didn't really search for it, but it wasn't obvious either.

Re: Re: Debian standard installation media packages

[Jacques Toerien]

Hi, thank you for the response. 

> Which image exactly are you using ?
Please tell the download URL and a checksum after download (MD5 or some
SHA*).

This is the image I’m now using. (see note below at end of message re. Buster)
https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/buster_di_rc1+nonfree/amd64/iso-dvd/
 


So, firstly, I made a mistake when I downloaded the image, I managed to 
overwrite the full DVD image with the netinst one (but kept the name), hence 
the missing packages - My mistake completely. I’m currently running Buster RC1 
and the installed system works fine. But...

> But first you should try to find out why you don't get the software
of build-essential. Then you can ask the right questions about a remedy.

OK, I have a done a full install using the expert install method, selecting in 
this instance Gnome as a DE. I have also selected the standard utilities. There 
is no way in the installer to selecting anything else, apart from the various 
DE/WM builds, ‘print server’, ‘ssh server’ etc etc. There is no option to 
select ‘build-essential’ or ‘Development Tools’. The installer finished by 
installing ~1366 packages. 
The installed system boots fine, I log in and do a 'dpkg -l’ to list all 
packages and there is no trace of any development tools. On my installed system 
I’m missing ‘g++’, ‘make’, ‘dpkg-dev’, ‘fakeroot’ and everything else 
associated with the ‘build-essential’ meta package. I don’t have any kernel 
headers either. I have ‘gcc-8-base’, but that is all in reference to build 
tools.
The 'build-essential’ package is on the install USB image, I just cannot find a 
way to install it directly to my machine without getting sucked into dependancy 
hell. 

I still don’t understand why the installer won’t allow you to select 
‘Development Tools’ as an option when you select packages? Surely it’s a key 
package to have if you don’t have net access while installing the OS? Is this 
to be taken up with the debian-cd list?


Anyhow, I sorted the install image so I can hopefully move forward now. 


PS - The reason I’m using Buster and not 9.8/9.9 is the older installer on 
9.8/9.9 gives an unreadable display on the HP 6470b laptop I’m installing on. 
On Buster I can pass ‘gfxpayload=keep’ in the grub command line and it allows 
for a readable display. This is a known issue with this older range of HP 
laptops.

For the benefit of -user readers who might stick with this thread, note
that the installation of cups-tea4cups is the choice of a user. On being
installed it does nothing and requires configuration. We do not have a
glimmer of what it is being used for and what was put in tea4cups.conf.

Re: OpenGL forwarding via ssh session: works on jessie, does not work on stretch

[Simon S]

Hi!

Thanks for testing it out!

I was wondering if it had to do with an user beeing logged in to lxde.
I think autologin might be enabled on the jessie system.
Unfortunately this does not help. Still the same problem on stretch.

I have some additional info. Without exporting the inderect rendering flag it 
does not work on ssh either:
> glxinfo|head
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
Error: couldn't find RGB GLX visual or fbconfig
name of display: localhost:10.0
...

With the export still the same issue:
>export LIBGL_ALWAYS_INDIRECT=1; glxinfo|head
Error: couldn't find RGB GLX visual or fbconfig
name of display: localhost:10.0

And there are no X error messages in the log either.

I was wondering if it has to do something with the gl libs on the armhf build.
Does your stretch based image have 
/usr/lib/*ARCH*/libGL.so.1.0.0
or
/usr/lib/*ARCH*/libGL.so.1.2.0
installed?

On jessie i havce 1.2.0, on stretch 1.0.0.
The 1.2.0 seems to be in a "transitional package" that does not install 
anything useful?!
Not sure if this is meaningful as glxinfo runs under lxde just fine.

Adding iglx to the config on the BBB allows me to run glxinfo with DISPLAY=:0 
(otehrwise I get  X Error of failed request:  GLXBadContext).
But it did not change anything for running gl stuff on a remote screen.
I also think the xserver on the BBB should not be necessary for running stuff 
via ssh -X on a remote screen. I think I killed the server on jessie once and 
ssh -X still worked fine.

My ubuntu box is running with iglx. In addition running indirect GL stuff works 
for the jessie box on windows too. Again it does not work on stretch.

That would be very difficult to achieve with systemd, your best option

Not an option for boot messages, but journalctl has some advanced 
filtering options that one can use, e.g. '-b -u ssh' will show only the 
messages from the current boot and from units matching the pattern 
'ssh'.

If you only care about possible problems -p (priority) could also be 
useful.

It shouldn't be very difficult to script something based on that.

No idea what this hardware is, but if it is USB, it would work as any

I installed some time ago from mozilla.org version is 63.0.1 and there is no
alsa in the about:buildconfig. Actually neither alsa nor PA.

I have heard that after investing so much time in PA they decided to
obsolete it, but it has been adopted by so many applications that it is
hard to go back now.

I've been following PA recently (since v.8) and should admit that 12.2
(which is in buster - I think actually it is 12.4, but not sure anymore) is
the best version ever. I compiled debian packages at 12.2 for stretch and I
must admit all my use cases work.

tea4cups=printer screwup

[Gene Heskett]

Greetings all;

I just removed tea4cups, totally.  Why? It totally screws up a print job.

First, it prevents the use of a printers duplex ability, thereby doubling 
the use of paper.

Second, it spits out the single sided job it does print, face up so the 
stack requires a hand sort to put page 1 on top of the stack.  Sheesh.

Surely the printer folks can do better than that. So its gone. Nuked. 
Removed. Deleted.

Any kind of disk\partition manipulations should begin with data backup,
but I think you've figured that by now.

In order to recover any data you should first stop using this HDD (don't
mount it as writable) and get yourself another HDD with suitable size,
that will serve as destination for recovered data.
You'll have to remove HDD from your notebook and connect it to a PC with
standard SATA cable along with destination HDD.
With that setup, you have to use R-Studio software (They have free
version for Linux partitions, IFAIK) to scan source HDD for traces of
partition table and LBA offset of partition that was "sda8".
If R-Studio will manage to find right offset and recognize filesystem
then you will be able to start automatic scan for files available for
full or partial recovery.
Success is solely depends on how destructive was HP system recovery process.

Depending on how valuable your data was you probably will have to resort
to professional data recovery services, which will do roughly the same
procedures as I described above and charge substantial amounts of money
for it.
Since you won't write anything to your source HDD and it is not
mechanically failing, it is safe to try to recover data by yourself first.

Recover data from unallocated space

[Vipul]

I had a dual booted PC ( Windows and Debian in HP notebook with 1 TB hard-disk) 
and from few months Windows cannot starts ( because one day I was in hurry 
change size of two of partitions using "gparted' and to fix this I had many 
solutions but failed) so, yestarday I decided to fix it by using HP system 
recovery option. When I run system recovery whole system was freezed for more 
than half hour so, I decided to forcefully shutdown machine by pressing power 
button after that I power on my machine BIOS message shows "No operating system 
found" ( all EFI files are deleted even which are in HP folder) and I ended up 
with like this

/dev/sda1  567296  158795775 158228480 75.5G Microsoft basic data
/dev/sda2   158795776  159942655   1146880  560M Microsoft basic data
/dev/sda3  1920552960 1953513471  32960512 15.7G Microsoft basic data
/dev/sda42048 567295565248  276M EFI System


And an un-allocated space of 839.4 GB. I mainly concerned about data in Linux 
partition data (which was in sda8).

Is there a way to recover data from un-allocated space? I can send any kind of 
log if required.

Any help would be greatly appreciated. Thanks.

This might as well be selection bias: folks avoiding Pulse are in for
it and may be readier to Know What They're Doing (TM).

I never installed it to begin with.  And my primary browsing has been in
google-chrome-stable for quite some time now, mostly due to the fact that
at the time I switched over, Firefox's javascript performance was simply
too slow for the kinds of web games I was playing.  Firefox's unilateral
out-of-nowhere decision to stop supporting the vast majority of user
add-ons wasn't a plus, either.

When I do youtube stuff in google-chrome-stable, it just works, and I've
never had to mess with anything other than un-muting and raising the
volume through alsamixer.  At least not on my last couple systems.
(Before those, I had a system with on-board audio and a sound card, and
ALSA had to be beaten over the head to tell it which device to use.)

So, ALSA is definitely not perfection, but I've heard far more horror
stories from Pulse Audio users than from ALSA users.

For the record, .bash_profile is only read by login shells, so your
suggestion only works for situations where one logs in with a shell
(Linux virtual console logins or ssh), not where one logs in with a

As does firefox-esr 60.6.3esr-1 in buster, it seems.  I didn't know about
about:buildconfig before.  Handy.

I don't know the exact story, but I've heard pieces of it over the last
year or two.  Apparently at one point upstream decided not to support
direct ALSA any more, but they left the code in place, just not enabled
in the default compile-time configuration.  Debian's packages re-enabled
the option to turn on ALSA support.  I was also told that, at some later
point, upstream actually removed the ALSA code from their source tree,
or was planning to do so.  I don't know if Debian is patching the ALSA
code back in, or if the versions we have just haven't been neutered by
upstream yet.

No, I don’t think so.
IIRC: In the beginning of ALSA you needed a soundcard with hardware 
mixing capabilities. Later, ALSA got a mixer plugin itself.


So, you don’t need Pulse to have multiple audio sources.
And if you only have one soundcard, PulseAudio is overkill. Besides, 
PulseAudio lies on top of ALSA.


The advantages of PulseAudio are:
- more than one soundcard, maybe even changing (onboard, USB soundcare, 
 headset, etc.)
- you want to move the application from one soundcard to another without 
 reconfiguring the application to the new soundcard

- network capabilities

Shade and sweet water!

What miffs me is that no-one in this thread seems to really care
enough to go check the sources. But then, some still seem to care
enough to go ballistic and complain loudly.

As I said, I'm happy with my Firefox having no sound (it hasn't;
actually I do prefer it that way), so I haven't done any research
into why.

What is your distro's version? What is your Firefox's version?

Anyone out there care to download the Debian source package and
check what the compile options are? This *must* be visible in the
Debian-specific patches, right?

But I believe I can perfectly wait with taking action until it becomes
necessary and decide then what to do.

And when everyone seems to say that there is no sound in firefox without
PA, it appears to be definitely not true for now, at least with debian
stable.

Hmm, I just uninstalled PulseAudio and Firefox audio still works, so I
guess Debian are still enabling ALSA in their builds. As others have
pointed out, this is likely to not be the case in the long run.

Think I may have installed PulseAudio as an effort to get Google
Hangouts video chat working in the Chromium browser. Just tried that
and with ALSA, I can't seem to get it to use headphones even when they
are selected explicitly by name.

unattended-upgrades downloaded package information only from the sources in sources.list.d directory ignoring sources.list file

[Martin T]

Hi,

in order to test unattended-upgrades I downgraded yesterday(4.06)
packages iceweasel, qemu-utils and thunderbird:

# # "apt list --upgradable" command below was executed on 4.06
# apt list --upgradable
Listing... Done
iceweasel/stable 60.7.0esr-1~deb9u1 all [upgradable from: 52.9.0esr-1~deb9u1]
qemu-utils/stable 1:2.8+dfsg-6+deb9u6 amd64 [upgradable from:
1:2.8+dfsg-6+deb9u5]
thunderbird/stable 1:60.7.0-1~deb9u1 amd64 [upgradable from: 1:60.6.1-1~deb9u1]
#

As expected, the unattended-upgrades ran today(5.06) morning, but it
reported, that "No packages found that can be upgraded unattended and
no pending auto-removals". Indeed, when I checked for example "apt
policy iceweasel", then the apt saw the installed version as the
latest one:

$ sudo apt policy iceweasel
iceweasel:
  Installed: 52.9.0esr-1~deb9u1
  Candidate: 52.9.0esr-1~deb9u1
  Version table:
 *** 52.9.0esr-1~deb9u1 100
100 /var/lib/dpkg/status
$

"apt policy" listed only the repository configured in
/etc/apt/sources.list.d/digitalocean-agent.list while ignoring the
ones in sources.list:

# apt policy
Package files:
 100 /var/lib/dpkg/status
 release a=now
 500 https://repos.insights.digitalocean.com/apt/do-agent main/main
amd64 Packages
 release o=. main,a=main,n=main,l=. main,c=main,b=amd64
 origin repos.insights.digitalocean.com
Pinned packages:
#

After executing "apt update", the rest of the repositories were again
seen in the output of "apt policy" and for example, the iceweasel was
again upgradable to 60.7.0esr-1~deb9u1:

$ sudo apt policy iceweasel
iceweasel:
  Installed: 52.9.0esr-1~deb9u1
  Candidate: 60.7.0esr-1~deb9u1
/* output removed for brevity */
$

Looks like the "apt update" or equivalent ran by unattended-upgrades
ignored the /etc/apt/sources.list file and used only
/etc/apt/sources.list.d/digitalocean-agent.list as a source for
repositories.
What might cause this behavior?


thanks,
Martin

Straight from the Horse's Mouth:

  "ALSA support was dropped starting Firefox 52.0 and later.
   Some Linux distros may have delayed this change with their
   own third-party Firefox packages to use ALSA until more
   recently.

   You could compile Firefox yourself with --disable-pulseaudio
   --enable-alsa

   Keep in mind that if you do this you will not get updates from
   Mozilla as it will be a third-party build."

(see e.g. [1]). Checking what options your distro compiled it
with is left as an exercise to the reader :-)

Now don't expect your distro maintainer's to continue indefinitely
maintaining your firefox's port in a non-standard configuration.

This is significant work, so if you care about it, do step in.

really? Here I can play back a video in firefox and play another video
from harddisk in vlc and the sound tracks are happily mixed by alsa (not
that it's an enjoyable experience, but it works :)

is that actually true? Here I can watch videos on yt or vimeo for example
in firefox with sound perfectly intact without pulseaudio installed.
In which situations does sound in ff not work?

Re: Date format for Thunderbird 60.7 -- partial success in changing it

[Jörg-Volker Peetz]

As user of thunderbird you best set the environment variable LC_TIME in your
profile, e.g. via ~/.bash_profile . Check it with the command

$ locale

You have to log out (from desktop and from computer) before changes in
.bash_profile get applied.

I ended up with a following wrapper:

$ cat /usr/sbin/sendmail
#!/usr/bin/env bash

# As header fields are at the top of the message, then following substitutions
# should work reliably.
sed '0,/^Subject: =?utf-8?q?apt-listchanges=3A_changelogs_for_vps?=$/

Andrew,

I guess it works for you because bsd-mailx depends on virtual packet

Because... Reasons. What is a "modern GNU/Linux OS" anyway?

This ain't very helpful. More detailed: if you want your Gnome
desktop environment to work "out of the box" and your (newer)
Firefox to have access to sound, you're better off with Pulse.

If you don't care about those things -- or are in for some
fiddling -- by all means, drop Pulse, and tell us others about
it!

See? I'm happy my browser has no sound, at last :-)

Thing is... if you ban pulseaudio, you should know that many "desktop
environments" and other so-called "modern" [1] software rely on it.
So you should know what you're doing or you should be willing to learn
things.

In that case, it can be quite rewarding.

In a nutshell, I'd say: if you want to *just* use your distribution
as a tool that Just Works (TM) and tend to opt for "the defaults",
just use PulseAudio. If you want to tinker and learn (which doesn't
mean that your distro will be useless!), dropping one or two of these
migth be a rewarding avenue.

Thanks to Debian and to all of you hard-working DDs and other Debian
folks for making both avenues possible! [2]

Cheers

[1] The problem with "modern" is that it carries with itself a value
   judgement, as a stowaway, so to speak. If you ain't "modern", you're
   a luddite or something. That kind of thing makes communication hard.
   It's difficult to listen, with all that shouting.

Re: Authentification failure

[Eric Degenetais]

Il y a 5 ans déjà, je constatais des scans à longueur de journées sur l'ip
publique serveurs sans nom de domaine, dès leur première journée. Il y a
clairement une exploration systématique de certaines plages IP à la
recherche de serveurs à subvertir.

Like Firefox, that was the reason I relented and installed Pulse Audio
(to listen to online video).
