Where did you read that? That seems like a huge waste of time.

As far as I remember, the idea behind this suggestion is to help the SSD 
firmware detect bad blocks or cells early on and to mask them out. Of course, a 
good firmware with it's wear leveling algorithm 
(https://en.wikipedia.org/wiki/Wear_leveling) should do this by itself.

Re: Orphaned Inode Problem

Hi,

did you take a look at the smartctl output?

Somewhere I read, for maintainance of an SSD all it's cells should be read from 
time to time like this


sudo dd if=/dev/DEVICE of=/dev/null bs=8M status=progress

where device is something like sda or nvme0n1, especially if it was switched off 
for a longer period. At least, it shows the current read performance of the device.
An SSD should regularly be trimmed, if in use. This is to assist it's wear 
leveling process.


What's your opinion?

In this category of computer aided mathematics or computer algebra systems,

octave and scilab bring there own GUI.
sagemath and also python 3 or R can be used via jupyter notebook which is a kind
of browser based GUI.

But these are all way to heavy programs for doing simple calculations.
For that I also use `bc -l`. It has a line editor: you can write your whole

But at the moment I'm lost how this interacts with pulseaudio.
At the same time the /pulse directory is created, there is created an also empty

The /pulse directory is created at boot-time. The pulseaudio process is started
at login on this system. Also, pulseaudio continues to work after removal of
/pulse which is always an empty directory. It has uid 0 and gid 0 an is not
readable for group or others.

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.

No, version 1.17.9-1 of cups-filters recommends imagemagick unversioned.

dummy imagemagick package.

Taking another look at package imagemagick-6.q16 (version 8:6.9.7.4+dfsg-16) it
states that it provides imagemagick. Therefore, I don't understand what's going
on on your system and there's nothing wrong with package cups-filters, I think.

Re: Can imagemagick really be safely purged or removed?

I forgot that you showed the dependency on cups-filters in your original mail.
On testing cups-filters 1.17.9-1 does not depend on imagemagick, it only
recommends it. And I use APT::Install-Recommends "false"; in /etc/apt/apt.conf.
Therefore, on this system imagemagick could be removed.

Since I use a pure 64-bit system, I overlooked that only one of

Re: Can imagemagick really be safely purged or removed?

[Jörg-Volker Peetz]

Take a look which imagemagick packages are installed:

$ aptitude search '~iimagemagick'

Probably there is a line beginning with

i A  imagemagick-6.q16

which shall replace imagemagick. Also see the dependencies of package 
imagemagick:

$ dpkg -s imagemagick

So before purging imagemagick you have to

$ aptitude unmarkauto imagemagick-6.q16

The blog page mainly states a procedure which worked also on other devices like

I'll second this. The ip command is nearly as complex as git. The CLI help
is also usefull, like

$ ip help

and then

$ ip addr help

In the end, may be, you're satisfied with the output of

The file /etc/issue belongs to package base-files (dpkg -S /etc/issue)
There is no newer version of this package in sid than that of testing which is
version 9.8. Therefore, you see "9.0" in /etc/issue.

More helpful is apt-show-versions (from the package with the same name):

$ apt-show-versions | grep unstable

I'm using a mixed testing/sid system and have also experienced such sudden
deaths of icedove with version 45.6.0.
A few hours ago I did the transition to thunderbird. It went really smooth by
upgrading the iceweasel*/iceowl* packages (it makes a backup of ~/.icedove and
generates a new ~/.thunderbird from that), and after using some
unmarkauto/markauto and purge commands there are now only the
thunderbird*/lightning* packages on the system.
In my lxpanel config I had to replace icedove.desktop by thunderbird.desktop,
the firefox Application "mailto" was adapted automatically.
All runs smooth so far.

There's also "make localmodconfig" which builds a kernel based on the current
config and loaded modules. See the "README" in the kernel source directory.

Re: Duplicating a partition's directory structure - How?

[Jörg-Volker Peetz]

In order to separate reading from writing or to store the directory structure
for several writings one can use find and tar:

  find PATH -xdev -type d -print0 \
| tar cf FILE --no-recursion --null --files-from -

The directories will be stored in the file FILE. It can be extracted with

  tar xpf FILE -C DESTINATION

where directory DESTINATION must already exist.

A nice tool for reading man pages as well the info pages is emacs.

For info pages, start emacs and do "Ctrl-h i". Then you can navigate the info
pages with the mouse-pointer and -buttons. You can do a local search in the
current page with the emacs-typical "Ctrl-s" and even a global search through
all sub-pages with just "s" and entering the search term.

Man pages can be displayed with "Esc-x man Ret" and entering the name your
searching a man page for. The name can be completed with "Tab".

Thinking about it, I would even reduce it to

gparted

and add packages still missing one by one.

Re: Manually installed packages

[Jörg-Volker Peetz]

Speaking of aptitude, it does remove automatically installed package if no other
package depends on it, or recommends it. This behavior can be changed by
configuration entries in /etc/apt/apt.conf, /etc/apt/apt.conf.d/*, etc.

To show any installed packages that aren't "auto" and which are dependencies or
recommendations of other packages, in short, packages that aren't marked "auto"
but could (should?) be, order

  aptitude search '~i!~M(~R~i|~Rrecommends:~i)'

Go through this list and, as root, mark the ones you don't need with

  aptitude markauto PACKAGE

When done,

  aptitude search '~g'

shows what can be purged from the system.

Regards,
jvp.

Re: Manually installed packages

[Jörg-Volker Peetz]

Here you have the answer to your own question.
Use apt-mark to mark the packages you want to keep and all "required" packages
as "manual"ly installed. Then mark all other packages as "auto".
Then let
  apt-get autoremove
do its work.

After that, use e.g. aptitude to remove remaining configuration files with
  aptitude purge '~c'

jvp.

The number of installed packages can be counted with aptitude as

  aptitude search '~i' | wc -l

As others have explained the search with '~Astable$~i' does show packages which
are installed and are available in "stable" but maybe not with the same version
which is installed. Therefore, you probably counted some packages multiple.

Or just with aptitude:

aptitude -F "%p" search '!~Atesting!~Aunstable~i'

At least on my system it produces the same list of packages.

This needs a correction, if I'm not mistaken:

aptitude -F "%p" search ~i | sort | \
(aptitude -F "%p" search ~Aunstable ~Atesting | sort -u | \
 comm -23 --nocheck-order /dev/fd/3 -) 3<&0

All installed packages should be checked, not all available from stable.

All three archives have to be present with the names used above in your

This is due to the last hardening changes in gcc-6 after 6.2.0-7 see bug reports
#841368, #841500, and #841533.

Re: Partial Success [was: Re: Problems with upgrade from Wheezy to Jessie]

[Jörg-Volker Peetz]

Hi Hans,

so the radeon driver seems to work but maybe needs some tweaking.

1) Let's have a look at Xorg.0.log.
 grep -i chipset /var/log/Xorg.0.log
 grep -i render /var/log/Xorg.0.log
   (Maybe, append the file to your message)
2) Is there a file /etc/X11/xorg.conf?
3) Take a look at the man-page of "radeon" (man radeon)

Regards,
jvp.

Re: : Problems with upgrade from Wheezy to Jessie

[Jörg-Volker Peetz]

Hi,

I also saw the other e-mail exchange with Brian where you concluded to purge all
"fglrx"-related packages. Similarily, there seem to be "nvidia" packages on your
system. Try

 dpkg -l | grep -i nvidia

Purge them also. Then have a look which xorg-video drivers are left:

 dpkg -l | grep xorg-video

Leave only xserver-xorg-video-radeon on the system.

And have a look if there's still an "glx-alternative" package left, like
glx-alternative-mesa. This could also be purged.

Regards,
jvp.

Is this file really present on your system? What does

  ls -lF /usr/lib/xorg/modules/linux/libglx.so

show? Is there a link somewhere in this path?

  ls -lF /usr/lib/xorg/modules/linux
  ls -lF /usr/lib/xorg/modules

According to Xorg.0.log it should belong to some NVIDIA package.

What does

  dpkg -S /usr/lib/xorg/modules/linux

print out?

You used '~U' in the first and the last command, not '~ahold'.
This last command could also be written shorter:

  aptitude -y -v -s full-upgrade '~U' | ...

There's also the switch '--remove-user-tag':

  aptitude -y -v -s --remove-tag hold full-upgrade | ...

Does this what you want?
