 Si lo que quieres es cambiar el entorno de escritorio predeterminado
 por aquí dicen algo:

 The easiest way to accomplish this (the way I actually did it) is to use
 update-alternatives:
 
 # update-alternatives --config x-session-manager
 
 corriendo este comando (que recorde gracias a tu lectura :)) me aparecen
 
 update-alternatives --config x-session-manager Existen 3 opcioens para

Si no te aparece alguna entrada que apunte a fluxblox puedes añadirla 
manualmente (man update-alternatives). 

De todas formas, revisa también los comentarios #7 y #9 donde indican dos 
opciones más para seleccionar el entorno predeterminado en el gestor de

Tienes una aproximación en la wiki de Debian:

 si monto un cluster con maquinas de arquitectura ARM y le agrego los
 paquetes de arquitecturas 32 y 64 bits, ¿puedo ejecutar los programas
 para esas arquitecturas en este cluster?

Hum... con binarios de 32/64 bits no hay problemas porque son 
arquitecturas compatibles pero armel es otro cantar. Compilar creo que sí 
podrías pero ejecutar binarios me parece que no.

Investigando un poco, me topo con que (1), la versión actual de
chrome-chromiun ya no soporta NPAPI, plataforma desde donde se basa la
ejecución de aplicaciones propietarias como Java, Flash y
Silverlight. Paradójicamente, yo actualicé chrome para poder instalar
éste último a través de pipelight, como requisito para hacer unos
trámites gubernamentales...

(...)

La plataforma para declarar y pagar impuestos está fuertemente casada
con Java y Silverlight.

Sí, aquí sucede algo parecido, nuestra agencia tributaria (AEAT) usa Java
pero me parece que la aplicación no se ejecuta como applet sino que se
descarga y se ejecuta fuera de línea y sin intervención del navegador lo
cual es una ventaja.

Es un tema que el gobierno debería de solucionar, pero en definitiva,
la falta de plataformas actuales y seguras, -y, creo, la guerra que
llevan entre competidores google-oracle-adobe- es un tema que no
precisamente abre las puertas hacia una solución adecuada. Si millones
de mexicanos le mandáramos al gobierno una solicitud para cambiar sus
plataformas de declaración y pago de impuestos. ¿que solución
contundente les pondríamos ? nada se me ocurre.

Yo, al gobierno le doy todo lo que puedo en soporte papel :-)

En fin, una buena forma de terminar la semana.

Hay muchos bancos que también usan java para realizar gestiones, y
también se usa para acceder a sistemas integrados (appliances) o
conexiones remotas a sistemas virtuales, no sé si Chrome va a poder
soportar la situación sin java por mucho tiempo porque la opción de
usar una versión anterior que tenga problemas de seguridad no creo que le
haga gracia a nadie.

paradójicamente, Java ha sido la única plataforma capaz de impulsar
todo tipo de operaciones desde, básicamente, su nacimiento.

Por el momento, en lugar de desinstalar chrome y voltear la mirada,
tomé el camino posiblemente inseguro. Instalé la version 34.
Java y Silverlight (pipelight) funcionan, aunque hay algunas páginas
del portal a las que no puedo acceder. Ésas tareas se las voy a dejar
a mi contador, y su flamante Windows XP.

Me llama la antención de algunas opiniones (actuales y anteriores)que
se han presentado en el foro de desarrollo de chromium sobre el tema
(1)

Personalmente, ésas opiniones me parecen poco propositivas para la
comunidad de SO. Si los desarrolladores de los navegadores comparten
ésa opinión, me daría preocupación.

Conectar a dispositivo de mídia (MTP)

2014-05-31 Thread Márcio Vinícius Pinheiro

Caros colegas,

tenho um celular Moto G e não tenho conseguido conectá-lo ao Debian. O
celular me dá duas opções de conexão:
- PTP, pela qual ele funciona como se fosse uma máquina fotográfica. No
Debian, tenho acesso apenas às pastas de fotos, pelo Shotwell ou pelo
Nautilus.
- MTP, pelo qual eu teria acesso ao dispositivo como se fosse um pendrive
(pelo menos é assim no Windows), me dando acesso a todos os arquivos.
Quando conectado por esse método, o Debian sequer acusa sua presença.

Como faço para ter meu celular reconhecido no Debian? Tem como?

A opção discard é que habilita o uso do TRIM pelo ext4. Portanto se 
você adicionar o discard nas partições do seu SSD (no /etc/fstab) não 
é necessário nenhum parâmetro extra no rc.local nem no cron.

Pois é, parece que a não recomendação de uso do discard é devido a 
alguns firmwares bugados.

Nesta thread é tratado um problema destes no ubuntu:

Aqui tem um post do Ts'o sobre o assunto:

Agora no ubuntu 14.04 tem inclusive um script no cron (fstrim) para 
fazer o trim semanalmente, mas ele só executa nos SSDs Intel e Samsumg, 
justamente devido a estes bugs.


Eu tenho um Kingston SV300S3 e ele tem funcionado normalmente com o 
discard, apesar de que eu não faço uso pesado de gravação nele.

 Between those extremes are things like LXDE, which provides quite a few

 and applets built from the ground up to interact with it.
 
 If I stretch, I could even make an assertion that a DE is a document

 add to your OpenBox. The document could tell how to install
 suckless-tools and then add dmenu_run as a hotkeyed option for quicker

 I guess what I'm saying is this: I know KDE is a Desktop Environment,

Prevent upstream packages from replacing locally modified packages

2014-05-31 Thread drupsspen

Hello.

I have created a local package repository that I access over my local
network using NFS. I have so far used this repository for managing packages
that I want to install but that are not distributed with Debian. This works
fine but I have now run into a situation where I want to take a package
that already exists in Debian, change it and rebuild it and distribute on
my own machines. This creates a potential problem:

The potential scenario is that I rebuild the source package with my changes
and installs it on my own machines. Some time later the version of the
package in Debian is updated slightly. My machines see that there is an
update in Debian and installs it, replacing the custom package including my
changes.

Is there a way for me to configure Debian so that if a package is installed
from my local repository then updates to those packages should only be
installed from that same repository?

Thank you!

Try the following commands:

This command will search and remove packages and his configuration with no  
dependencies. But maybe you like/ need the package


$ deborphan

Prints (default option) a list of libraries which are unused. You can  
remove these packages with

$ sudo apt-get remove --purge `deborphan`
(deborphan can also search for programs that are orphaned, but I will get  
a lot of false positives)

Cruft search for files on your system which doesn't belong to a package.

 1.5GB isn't bad. But if you have just 1GB, or 768MB, or 256MB, or
 whatever figure, can you still run a default Debian? How low can you
 go, without fiddling around enormously?

Debian performs nicely with 512 MB RAM in my experience if the CPU and 
video card can keep up.

 It's a bit more than just playing videos; it's a set of related tools
 for managing them, controlling playback remotely, etc. Not huge, and
 I'm sure I could create a massively cut-down system (is it possible to
 run VLC on top of X without a window manager??) and fit the same tasks
 into far less memory and a far less powerful CPU, but that would
 require a lot more fiddling.
 
startx /usr/bin/vlc

 Hmm, not sure that default Debian performs as well. My first
 Linification of that hardware was with Debian Jessie as of whenever it
 was I did it (earlier this year sometime), running Xfce with all the
 defaults. Playback, while immensely smoother than it had been under
 Windows, still glitched fairly often on largeish files. Now, with
 AntiX, the glitching is only on the highest of bit-rates, again with
 basically all the defaults, so I'd say there is a performance
 difference between the two. What the cause of that difference is,
 though, I can't say.

Xfce might be a bit much, depending on your processor and video card 
(you still didn't mention them). LXDE or just plain OpenBox should 
perform better.

Re: Create backup of system-connections on a USB stick

On my system the files under /etc/NetworkManager/system-connections/ are

Probably simplest is to switch to root an copy the files to the stick. 
Be careful what you do with that stick, those files are protected for a 
reason (they might contain passwords or so).

Also if the stick is FAT32 you will loose all information about

interpreting Gkrellm charts

I'm running Debian/Jessie on an AMD64 system using KDE. My system 
periodically grinds to a halt for a minute or so then resumes as if 
nothing had happened. This only happens when I'm running KDE. Gnome and 
xfce work properly, even with the same applications open.


I recently installed Gkrellm (using default settings) to see what is 
happening when my system grinds to a halt. The only unusual part I see 
in it is that the procs box has the brown line climbing to the top of 
the chart.  Interestingly, the slope of the brown line continues 
throughout the slowdown, which suggests that whatever it is measuring is 
continuing to increase.


There is also a sudden increase in disk activity. The two seem to be 
related as the disk activity does seem to happen only when the computer 
gets slow.


The slowdown ends when the brown line in the proc box starts dropping. 
I'm not sure what the line is supposed to be showing. Simultaneously the 
disk activity drops dramatically. Usually the disk activity is measured 
in k but when the computer slows down, it jumps up to M.


Iotop output doesn't show any particular process doing anything unusual. 
The same goes for top. Even Gkrellm doesn't show any significant CPU 
activity.


I have 16G of ram so the swap partition is barely used. Turning it off 
seems to have no impact on performance.


Any ideas on what would be causing a periodic slowdown in KDE? Or any 
suggestions on how to identify the source of the problem?

I don't care and btw. I don't claim that JWM is a DE. The discussion

about a fast GUI performance. After a while lightness in the sense
of how much RAM is needed for the WM/DE became the topic.

It's important to distinguish the RAM space of a WM that only does
handle windows, with a DE where already the desktop is a comfortable
file manager, at least to take care that the lightweight WM does need
more additional things that will need additional RAM.

Correct, JWM e.g. provides a panel by default, OTOH JWM anyway needs
less RAM than many other WMs and nobody is forced to use the panel, IOW
comparing WMs and DEs by the minimal needed RAM is tricky. A user should
compare the RAM usage, performance, stability by monitoring it for the
user's individual work-flow in combination with often needed apps.

If you need plugins other than PepperFlash, forget Chrome. Too bad.

Possibly not. Sorry, I'm actually using the prev theme, not the

the number of procs as a number. The number remains fairly steady over 
time. Under xfce (which I am currently using - this KDE problem is just 
too annoying), the (proc) brown line floats around a bit while the blue 
chart shows lots of spikes. Under KDE, the brown line goes well above 
the blue spikes. On the disk chart, the brown and blue charts show 
spikes in xcfe but jump to a solid high level under KDE during the 
slowdown - although I do have one saved screenshot where the disk 
activity shows a high number but the brown and blue charts are both at a 
low level.





There is also a sudden increase in disk activity. The two seem to be
related as the disk activity does seem to happen only when the computer

It could be swapping.
top will show swap useage. anything about about 1% of the swap memory
used suggests things have gotten swapped out, which means your memory
filled up and that will certainly slow things down (disk is about 1/1000
the speed of real memory)

I thought about that too, but it's not.

OK, so swapping is not the problem.

Also it could be that various helper programs (msec, akonida,
updatedb) are reviewing stuff in your computer.
Probably, but with top and iotop not showing any significant activity 
for any process, how can I track down which one?





Any ideas on what would be causing a periodic slowdown in KDE? Or any
suggestions on how to identify the source of the problem?

debian-user: Help and discussion among users of Debian

A lot is going on in the world outside Debian. Every user of Debian
should be free to raise any topic that (s)he believes is important to
the Debian 'mission', which heavily invested in the proposition that
software is and ought to be open and free (as in freedom). This is
what 'discussion among users of Debian' means to me.

The subject of the OP is Assange and NSA. NSA has been accused of
somehow infiltrating Debian and enslaving it. Assange is a celebrity,
well known to almost everyone in the computer world, for innovative
use of the internet to publish 'leaked' information. 

Any news event involving both, together, should be mentioned here,
because of the nature of Debian, what it is and what it stands for. 

I have found that the commercial news channels in USA do not report
this type of news very well or very quickly. How much discussion this
report deserves is up to us to decide, but only after we hear about
it.

This is pure guess, not a valid troubleshooting diagnostic test, but
back in the days when I had KDE libraries on my machine and used Kmail,
occasionally a KDE-initiated dbus-daemon process would go rogue and
consume upward of 95% of my CPU, sometimes 99%. I Cured the problem
with a script that hunted down long-running (5 seconds or more) 95% plus
dbus-daemon instances. Nowadays I have no KDE libraries or programs, so
I no longer use my script.

Top or htop would show what's burning up your CPU, or perhaps memory.

If it turns around it's rogue dbus-daemon processes, I can give you my
script.

They should be anti-aliased and all that.
You can select default fonts and stuff in the rc.xml file or with obconf

Re: interpreting Gkrellm charts

xfce work properly, even with the same applications open.

I recently installed Gkrellm (using default settings) to see what is
happening when my system grinds to a halt. The only unusual part I see
in it is that the procs box has the brown line climbing to the top of
the chart. Interestingly, the slope of the brown line continues
throughout the slowdown, which suggests that whatever it is measuring is
continuing to increase.

That is the number of processes that are running
The blue/green things there are how many forks there are within some
process.

Possibly not. Sorry, I'm actually using the prev theme, not the default
one (right-click on the header, select theme | prev). This shows the number
of procs as a number. The number remains fairly steady over time. Under xfce
(which I am currently using - this KDE problem is just too annoying), the
(proc) brown line floats around a bit while the blue chart shows lots of
spikes. Under KDE, the brown line goes well above the blue spikes. On the
disk chart, the brown and blue charts show spikes in xcfe but jump to a
solid high level under KDE during the slowdown - although I do have one
saved screenshot where the disk activity shows a high number but the brown
and blue charts are both at a low level.

My interest in reading and helping with the specifics of your problem
pretty much evaporated when you persist in using brown and blue as
identifiers, even after you realise that the colors change depending
on the particular theme you are using. I think you are more likely to
receive help if you make the effort to learn what all the gkrellm
plots represent and present your problem in those terms instead of
talking about the pretty colors. That will both improve your
understanding of what is happening, and make it easier for people to
help you.

In the gkrellm configuration for the proc builtin, you can read the
info tab that explains more about that. Also in the setup of the proc
builtin I have entered this format string
\w1000\e$p\f procs\w1000\e$l\f load\n\e$u\f users\w1000\e$f\f forks

It gives more information, but nowhere near what running 'top' offers.
I guess that the gkrellm curve you care about is load, so you
probably need to look at the load average numbers in top. Searching
for information on this will find useful links like these:

https://www.linux.com/component/content/article/174-tutorials/42048-uncover-the-meaning-of-tops-statistics

http://www.linuxjournal.com/article/9001

Also 'iotop' can tell you what process is doing disk read/writes, this
might be helpful if you feel that the slowdown is correlated with some
process that is disk-intensive.

Once you have the process ID numbers, you can use a tool like 'pstree
-p' to better see what initiates the offending process.

I have no idea about KDE.

If you right-click on the proc plot you can discover that one curve is
load and the other is forks. The fact that one may or may not be
above the other is irrelevant because they both autoscale
independently.
Actually I don't discover that at all. That information is hidden away
in an info tab when I right-click on the Proc name bar, not in the plot
area. The name bar doesn't respond to left-clicks, just to right clicks,
while the chart area responds to left clicks by turning the procs and
users info on and off.

It takes a fair amount of interpretation to guess that the line is
reporting forks while the vertical bars are possibly procs (or
vice-versa) since the the line graph goes up and down while the number
of procs reported stays constant. Similarly the spikes in the vertical
bar chart don't seem to reflect the stable number of procs being reported.

It would be helpful, but would require a larger interface, to have
on-screen labels for the various graphs, such as a tool-tip style popup
telling you what the line or bar is measuring.

My proc setup was \w88\a$p\f procs\n\e$u\f users. When I try yours, it shows
two more numbers in the right side of the chart area. The top number goes
between 0.6 and 0.8 from time to time while the bottom number jumps around
between 1 and 6.

Unfortunately, neither top nor iotop identifies a process as doing
anything remotely strenuous. However, iotop does confirm that the total
i/o going on when the computer is rather a lot. This is what GKrellm
also shows in a nicer format. The processes that iotop shows as doing a
little disk activity are the same whether the computer is running slow

 The potential scenario is that I rebuild the source package with my changes

 Is there a way for me to configure Debian so that if a package is installed

 installed from that same repository?
 
 Thank you!

As already pointed out, you can use APT-pinning. Another solution could
be to increase the version number of your package so that it will always
be above a Debian version and therefore ``updates'' will only be
considered if they have a greater version, i.e. are updates to your
modified version.

 cd /path/to/dir/you/want/to/copy/
 tar --exclude=file_that_should_not_be_copied -czf  
 /pa/th/backup_file.bak.tar.gz * .hidden_file

The asterisk * is appended to backup_file.bak.tar.gz or .hidden_file?

What is .hidden_file?

 You should read some howtos about how to use tar, e.g. how to restore data

Where is a reliable source for such info for Debian platform?

 Tails - Privacy for anyone anywhere
 - [T]he [A]mnesic [I]ncognito [L]ive [S]ystem (based on Debian)
 - this is a TOR project.

How is Tails relevant to answering my question?

Are you a troll?
