[gentoo-user] No sound from audacity...

[tuxic]

Hi,

got a strange problem with audacity:
I did:
Load a *.wav file into audacity (it contains sound as visible in audacity 
Menu->Select->Select all
Press play bottom

Nothing

This is printed on the console:

[gentoo-user] Terminal weirdness...

[tuxic]

Hi,

when updateing my repository of neomutt and build it it normally went
fine and the executable can be used. 

This was the case til the release dated 1.5.2020.

Afer that some hotkey commands were no longer recognized - the
keypress itsself was recognized, but either the wrong function
was executed or "key not bound" was displayed.
This is true for ^O for opening a folder of a mailinglist.
^N still works.

I asked people from the neomutt mailing list but the suggested
solutions didn't work:

stty flush undef

or instead

stty discard  undef


Now the next stable version of neomutt was released but
my problem remains.

Yesterday I was playing around with simh and tried
to boot and run some old unix v7 tapes.

While preparing the boot process simh prints
some weird characters on the screen, which were
not diplayed in the tutorial online.

I don't know, wheter this is related.

In the relevant time I didn't changed any terminal related/
language related or such things in my setup.

I simply don't know where to search for what to fix
this.

Any help is very appreciated!

Cheers!

Hi,

Just installed 'ardour' just to see for what this is good, then I saw
your posting.

I reinstalled linuxsampler to post the logs hereand it compiled
fine.

Don't ask me why...

If I come accross some more infos etc...I will post it here.

[gentoo-user] Kind of sample player?

[tuxic]

Hi,

Trying to express what I am searching for:

I have some samples of instruments play one or only a few tones.
For each there is one sample per tone.

I am looking for a software, with which I can play these samples
controlled by a midi keyboard. The samples should be played
in a way, that dynamic of the key and pitch are respected (therefore the
sample need to be modified on-the-fly).

Unfortunately I am neither a musician nor a native language speaker...

The only one I found in portage is 'linuxsampler', which fails to
compile with a lot of "deprecated" messages.

Is there any other software, which may be appropiate for this purpose
in portage?

Cheers!

Hi Tom,

thanks for the info! :)

In the meanwhile I have used Audacity...it has a "Sound finder" and
"Silence finder" tool under the "Analyse Tab", which has some very
handy parameters.

The result will be visualised before any split file is written and can
be manually corrected per segment and to each segment can be listened 
separately 
beforhand.

Cheers!

Re: [gentoo-user] [OT] splitting audio file at points of silence ?

[tuxic]

Hi Dale, hi Ashley,

thanks for all the help and informations! :)

In the meanwhile I found another way to split that file "as is"
(flac remains flac) with audacity.

Audacity contains a "sound finder" and "silence finder" analysis
tool, with which it is possible to set marks/regions in the file,
which mark sound and silence.

The tools are configurable. This way one can tinker with the
parameters until a near perfect match as acchieved and then
write out the files with File->Export->Multiple.

The visual representation of sound and silence is by far better
then test-listening all created files after each iteration with
any cli solution.

Cheers!

[gentoo-user] [OT] splitting audio file at points of silence ?

[tuxic]

Hi,

I want to split an audio file containing crow calls at points
where no crow call is. The "silence" in between is not exactly
"silence" but some low level noise.

Searching the internet for "split audio at silence" and similiar
gives me this link
https://unix.stackexchange.com/questions/318164/sox-split-audio-on-silence-but-keep-silence

which uses a program called "silence" to detect the silence.

Unfortunately I can't figure out, what package contains that program
or from where I can download that program.

The input audio is a flac file  and I don't want to convert this into
any lossy audio format to preserve as much as possible of the signal.

Where can I get this program ?

or

How can I split an audio file at points of defineable 
level of "silence" into several audio files in one go?


Cheers!

[gentoo-user] 100% CPU load is different to 100% CPU load?

[tuxic]

Hi,

yesterday I md5summed my hole system with find.|
xargsmd5sum

With options I set xargs to use all 12 thread and use as much args per
call as possible in one line.

After a while I checked the CPU with glance and it shows, that all
12 cores/threads were "loaded" with 100% each constantly over a
period of about 1h. The CPU temperature rises to about 47°C.

The CPU does not contain a GPU. Graphics goes extra.

Today I created again a CPU load over a comparable duration with
a constant 100% CPU load on each core/thread.

Interesting it does not take more than 3 minutes to reach 65°C CPU
temperature.

Both temperatures reflect the die temperature.

What is the difference between 100% CPU load and 100% CPU load to
create such an difference in temperature?
How is X% load calculated?

Cheers!

Re: [gentoo-user] clone root from HDD to SSD causes no video with NVIDIA driver

[tuxic]

Hi,

if even displaying the console login failed, then the hole display
system has gone nuts...but since the boot process as such (that is:
the bios prompt right after POSTing) is visible, I would say, that
there is no physical problem (that is: cable connected to port 2 of 
the monitor while the monitor is switched to port 1 and such).

I would try this:
Boot your PC, ssh into the PC and download the according
nvidia-drivers directly from NVIDIA of the same version.

quickpkg the installed drivers and remove them

Check whether /usr/src/linux links to the kernel
sources of the kernel version you are booting.

Install the NVIDIA-drivers you have downloaded.

Reboot.

Background:
The portage package does not install nvidia-drivers correctly -
in my case, X and such works fine but RTX/Optix which is used
by Blender was defunc. After installing the original package
and masked the one which came with portage everything works
fine.

Re: [gentoo-user] clone root from HDD to SSD causes no video with NVIDIA driver

[tuxic]

Hi Raffaele,

may be this could give some insight of was is happening.

You said, you are able to ssh into your PC. 
I would try the following: Boot the PC, ssh into it and disable the
start of X. Boot again: Are you getting the console login
successfully?

Can you check, whether /dev , /proc , /sys and other directories of a
special function are created and filled correctly?
Are the permissions ok?
Is /run available and setup correctly?

Are there any leftovers from the root@hd in /etc/fstab?

If you get to console successfully, is it possible to start X from
the commandline? What is printed on the terminal?
What does X.log say?

Hopefully we will find something to fix that problem!

Cheers!

[gentoo-user] Got a json file from YouTube...

[tuxic]

Hi,

via https://youtuberandomcomment.com/ ->Download all is it possible
to download all comments of a YouTube-Videoas a json file, which
contains exactly one, very long line.

This is exactly the formatting I would prefer to read
threaded comments ;

Is there something in portage, which is recommended to 
reformat/display this json-input into something more 
readable...?

Cheers!

The above setup is for alsa/jack/obs...right.
Since jackd does not start (it crashes) and I am currently not in 
the mood to fix an error which helps to fix a problem which should
fix a problem for an application which in first place was there to
help me to fix an issue to record from Firefox...I will try
pulseaudio -- despite the fact, that I really don't like it.

[gentoo-user] Screenrecording with audio from firefox

[tuxic]

Hi,

To record my screen with audio I installed 
obs and then simplescreenrecoder.

Recording the video stream more or less works (I cannot record a
firefox-window and need to record the full screen).

But recording the audio from the source which will be replayed
by firefox only give me a stuttering sinus tone.

According to different tutorials I watched the recording of
a gameplay works with video/audio which exactly mine setup.

Interestingly I cannot find the regarding options of both
screen recorders any more (the tutorials refer to older versions
of the recorders).

How can I record video and audio from the played source nonetheless?

Cheers!

I have not tested other systems yet.
It works fine with my old computer...but that it doesn't work now, may
be a coincidence in time and not necessarily a logical dependency.
I can't rememember of VirtualBox or one of its dependencies were
updates in the meanwhile...

As said, I have successfully run ReatOS on my old computer.

[gentoo-user] ReactOS with Virtual Box: B.O.D. Black Screen of (?)death(?)

[tuxic]

Hi,

I tried to install ReactOS into my Virtual Box which went fine
so far.
Booting itsself was no problem eitherbut instead of getting 
a desktop I got a simple uniform black screen.
No error messages so far...nothingonly the black void.

bugs.gentoo.org when searched for "ReactOS" or "black screen"
shows nothing related.

In the internet I found one anchient message from glorious
times, when bugs were real bugs ... ...
a message, which is no longer related due to its age.

Does someone run ReactOS successfully with virtualbox
and knows how to circumvent this BOD?

Thanks a lot in advance!

Why is tessdata are not pulled?

Hi,

I want to include "de" (german) to the USE flags for

How can I successfully define the language via USE flags

Hi,

I am a non native speaker -- when I asked using the wrong words.

My question was: 
"Is the bug tracker secureVud somehow against search machine robots somehow or 
via robots.txt or is it me using a foreign language wrongly?"

Hi Neil,

that works! Thanks  a lot.

A more general question: It is not the first time I searched for 
fixes for compilation failures I came accross and I never got a 
link into the gentoo bug tracker. As search terms I used
"handbrake gentoo compile failure".

Is the bug tracker secured somehow against search machine robots
somehow or via robots.txt or is it me using a foreign language
wrongly?

Cheers!

[gentoo-user] handbrake fails to compile

[tuxic]

Hi,

media-video/handbrake-1.3.2:0/0::gentoo fails to compile (I am on
"unstable").

Searching online I found, that running perl-cleaner would fix that
problem which I done:

perl-cleaner --all

 - but without success.

Message was:

 * ERROR: media-video/handbrake-1.3.2::gentoo failed (compile phase):
 *   emake failed

I attached the build.log. If any further information are added I will
be happy to post them.

How can I fix that?

Cheers!

[gentoo-user] How to manage load on the GPU?

[tuxic]

Hi,

sorry for the somehow vague subject line...no native speaker...

With Blender I do a lot of experimenting and tinkering which
involves rendering most of the time.

With rendering comes ... waiting for the result.

Often (I am trying to) watch videos, like tutorial about
what I currently trying to acchieve with Blender.

The problem is, that the video (the audio does not) stutters
in short periods. 

Interestingly it does this not every time but quite often.

And it only effects videos online.

mpv for example is not affected.

Is there any way to configure whatever it is in a way, that Online
videos can be played smoothlessly also?

Hardware:
AMD Ryzen 5 3600
MSI Ventus RTX 2060 SUPER (NVidia)
32 GB RAM

Any helpful idea is very appreciated!
Cheers!

Hi Dale,

Hi Dale,

thanks for your info! :)

I think it is called "Auto" with the MSI bios.
When using this, JEDEC timings and a command rate of 2
instead of 1 are choosen for DDR4 (as an example)...which
isn't optimal.

These "Auto" were the reason for better settings.
I think I have to tweak the bios settings by hand...

Cheers!

[gentoo-user] [OT] BIOS Best settings (no o.c.) for ZEN 5 3600 / MSI Tomahawk max ?

[tuxic]

Hi,

I am trying to figure out the best settings (performance wise) for a
AMD Ryzen 5 3600 with a MSI Tomahawk max motherboard.

I don't want to overclock -- tweaking the bios is for finding
the optimal setting in oposite to waste performance via sub-optimal
settings like not activateing XMP profile and running the RAM at
JEDEC speeds instead of what the vendor guaranties.

Unfortunately, there are quite a view settings to which I didn't 
find any explanation, for what they are good.

Any help is very appreciated! :)

I want to set 'jack' as a default USE flag - bu my system is a

Since the compilation process had run for a while, the logfiles are

Is there a fix known for this?

Is it possible to install the older version of boost somehow "in

[gentoo-user] Sensor readout (new PC)

[tuxic]

HI,

Still updateing/configuring/correcting/completing my new PC...

This time it is the sensors readout via 'glances'

My setup:
AMD Ryzen 5 2600. MSI Tomahawk Max, NVidia RTX 3600 SUPER
Kernel 5.6.11 vanilla
sys-apps/lm-sensors 3.6.0 

Beforehand I did a sensors-detect and answered every item with
"yes".

This is the final result:
|Driver `k10temp' (built-in):
|  * Chip `AMD Family 17h thermal sensors' (confidence: 9)
|
|Driver `nct6775' (built-in):
|  * ISA bus, address 0xa20
|Chip `Nuvoton NCT6797D Super IO Sensors' (confidence: 9)
|
|No modules to load, skipping modules configuration.


The readout via 'glances' looks like this (the temps are higher than
idle...currently a massive update is running... :) :

|SENSORS
|Tdie 63C   
|Tctl 63C   
|Tccd163C

fan1 and fan4 are not used, the readout is ok therefore. But PCH_* is
"0.0° C" as the other "???" marked values from above are.

On the internet I found descriptions of new formulas from the early
times of the Ryzen processors to correct existing readouts...but in
the case above, it seems, that there is no readout at all.

Are the lines marked with ??? "normal" or do I need some additional
configuring?

Re: [gentoo-user] New PC hangs/lacks ?

[tuxic]

Hi Walter,

thanks for your input again.

A said previously: This is not a problem of a high load,
which needs to be handled. This is kinda temporary deadlock.
Even if I would choose the best possible scheduler...the
CPU would not get the chance to execute the code of the scheduler,
because something locks the system. This description is meant to
describe the situation more than to describe the exact technical
background, for which I still search a solution to avoid it completly.

In the moment everything runs fine again, without haveing changed
any kernel configuration or anything else actively. /Something/
must have changed, though.

Cheers!

Hi,

since three days these locks nags me. Now, equipped with
a tablet, a ssh connection and an eye on the interrupts...
...no locks happen anymore.

Grrrmpppfff...

And let me guess: In the moment when I have the least
of an application for those locks...then they will be
back... :(

Sorry, I cannot reproduce the problem anymore.

Cheers!

Hi Mark,

Thank you for your help and ideas.

I will try to convince my tablet to connect to my PC and
will try to lock everyting which may point me into to the
direction of the problem.

To complete, what I previously wrote:
No, the disk is not doing anything beside holidays
in Honulu...so to say ;)

As soon I have something new "I'll be back"... :)

Cheers!

Hi Ashley! 

;)

Short explanation: With blender you can do animation.
For animations you need to "explain to Blender" how 
thing should move. This is done in the so called
"graph editor" which is - amthemtically spoken -
nothing more than a lot of X/Y graphs, where X
is identical to the current frame number - hence
the time axis - and Y is the amount of movement
in direction of one of the Ds in "3D".

Rendering is no problem (ok, the system "lacks"
a little, but that is expected since a lot of
calculation power is drawn).

But if I click into the graph editor to directly
jump to quite different frame than the previous
or next one, everything freezes.

Blender hast to end its calculations and THEN
everything goes back to normal.

In this time the CPU goes not in full load --
otherwise the fans would become very busy (as 
they do when starting rendering).

The problem here is not, that a sudden load is put
onto the system - that is normal and intended - the
problem is, that everyting locks up.

As said, it /feels/ like a lock on a system bus
or whatelse, what will only be released, when
the calculation for the frame jump has been
ended.

Since Linux is a multitasking and multithreading
OS and the PC has six cores and 12 threads, there
should be at least one thread left to handle the 
keyboard while calculating frames - IF the CPU
get the bus at all.

The example with the bus being locked is AN EXAMPLE
ONLY. I have no clue, whether something gets locked
at all and if so, what gets locked.

There is "nothing" else running except for the
usual daemons, the kernel, openbox, a shell, a terminal.
Or with other words: Nothing stressful.

And I /think/ (read: I don't know), I could have something 
to do with the communication with the GPU...:
If I switch of the preview, there are no locks anymore.

And I think my PC is causing the problem (instead of blender)
since the problem arises with three different versions
of blender.
Blender is used quite often, my PC is a combination, which
is used quite often and I didn't find anything (including
the bugtracker of the Blender development), which could
point me to the root of that problem.

On the other hand: I included the gpu-related USE flags
into make.conf and recompiled all related software.
Chances are there, that I would have triggered the problem
with another application if this problem is caused by
a bogus hardware (includind me screwing up some awkward
BIOS setting).

I am NOT overclocking and I am using "stock settings" in the
BIOS (beside the XMP settings for the RAM - but those are
settings quaranteed to work by the vendor of the RAM).

If any reader of the "Book of possible bogus hardware" is
now that confused as I am - you are welcome ! :)

Hi Walter,

Thanks for you help and info!

Buying a new machine is not an option, I bought this one 
a month ago. Take a look the specs.

Nice will also not help, since it is kinda "lock" that suddenly
kicks in. This is only an example: If a programm acquires the
system bus and hold it due to a programming error, the system freezes.
A nice would not help, since no one, who probablu could help to 
get out of this situation will get no processing time.

Sorry if I made myself not clear enough in this regard...I am
no native speaker.

[gentoo-user] New PC hangs/lacks ?

[tuxic]

Hi,

while rendering with Blender the system performance (especially
graphic related stuff) lacks. That's not nice but it seems that this
is the way it is designed.

What makes me a little nervous are freezes of several seconds. It not
onlu freezes but the whole graphical interface of everything locks
down (I couldn't find a corona computer virus, though).

In the Xorg log I found this:

[  2808.761] (WW) NVIDIA: Wait for channel idle timed out.

which possibly match such a moment of a freeze.

My setup:
Blender 2.90a (alpha) and Blender 2.83 (beta) and 
Blender 2.82a (stable).
All Blender versions show the same problem.

X11/Openbox

NVidia 484.82 as delivered by NVidia, since the Gentoo
package does not install all files of the driver which 
are needed for Blender (for example to support Optix).

No other application, which heavily uses the GPU was
running at that time.

MSI RTX 2060 SUPER
Ryzen 5 3600
32GB RAM
MSI Tomahawk MAX 

Does everyone has the same problems probably already solved
or any idea how I can those freezes?

Any help or idea what causes this freezes is very appreciated! :)

Cheers!

Hi Mark,

in the meanwhile I installed quite a few pulse-related applications
and pulseaudio itsself includeing pusleeffects.

For the first, the equaliser problem is kinda solved -- I haven't
checked, whether the settings will survive a reboot.

I don't know of the quality of the sound processing of the
equaliser...but it is definetlu a step in the right direction.

Hopefully all related applications I use will cooperate... ;)

Thanks to all of us who helped! -- very appreciated!

HI all,

thanks for the repsonse.

I am using waterfox, which is not in portage. The mentioning of 
Forefox was onlu to make its heritage clear.

I already have some "experiences" make, when it comes to other things
for audio than alsa.

Background to my question:
I am still searching for a equalizer solution, which does not
uses the eq provided by the hardware (I am using a DAC, which
does nothing else, than converting PCM into an analog signal.
No processing whatsoever.

So the eq has to have some sort of DSP funktionality build in.

And it should be made for background processing.

Anu helpful alsa-based idea is very appreciated...

Hi Wol,

Hi Dale, 

I am now running kernel 5.6.9 (vanilla) and nvidia-driver 440.82-r3.

Again, Blender cannot find the Optix related parts of the driver.
This package still does not work for me. As far as I can see,
the non-Optix specific things are fine, though.

So I will reboot, remove the portage package of the driver and
install the original by nvidia and this will fix the issue
with Optix...

Cheers!

Hi Dale,

hopefully I understood your question correctlu...

I am running currently the nividia 440.82 (not that one which 
portage...more in a second) with Linux kernel 5.6.8 and a
RTX 2060 SUPER jsut fine.

I few minutes before I had compiled kernel 5.6.9 but hadn't
rebooted my Linux yet.

I am using Blender, which starts to support Optix based rendering,
which is faster than "normal" GPU rendering.

Unfortunatelu "something" is broken, when using the portage version
of the driver. So I removed that driver and installed the same
version as offered by nvidia directlu and that worked.

This problem effects only Blender...as far as I know.

And: I haven't tried nvidia-440.82-r3 which is quite new. Will
try that when booting the new kernel and report later.

HTH!
Cheers!

Ok, the other way around: Does GPT hurt more than MBT on a external HD

Recently a BIOS update deleted all UEFI entries and the system no
longer boots. With rEfind from a USBstick I was able to boot
the sustem nonetheless and the reinstallation of grub solves
the problem.

Hi Raphael,

as far as I know, the hibernation mechanism of the kernel uses swap
as storage place for an RAM image.

If you plan to use hibernation, I think you need swap space in the
size of your RAM.

Hi Wolf, hi Andrea, hi Peter,

*Partition type '83':
I changed the type to 83 using fdisk and this worked fine. Now
/dev/sdb1 is recognized again.
Just to confirm this...
I think, I feel better if I repartitioning/reformat both drives,
though.

*GPT/MBR
>From a discussion based on a "GPT or MBR for my system drive" in

My question was meant not so much as "MBR or GPT?" 
but more whether there are some variants of GPT (with 
protected MBR for example -- which was completly new to me),
which I should use or avoid.

But: Are rescue systems for USB-stick more UEFI/GPT aware nowadays
or "traditionally" based on MBR/BIOS-boot?

One thing I found is really handy: An USB-stick with an rEfind
installation. As long as your PC supports UEFI (or can switched to it)
rEfind is able to boot "everything" without prior configuration.

Some rescue-system which really shines and with which you have made good
experiences?

Hi Andrea, hi Wolf,

this magic one liner does the trick indeed!  I have my data back and
copied it to my new system spread over four separate partitions, which
are currently still empty. No error while copuing and both disk
matched.

A very *#BIG THANK YOU#* for all the great help, the research and
the solution. I myself am back in "normal mode" :)

Wol has suggested to run mdadm on the bad harddisk to see, whether
this tool is able to fix it -- which I will next. Since I have
my data back on the PC internal disk, this is no problem at all.

One thing remains...
I want to prevent this kind of hassle in the future... ;)

Perhaps it is a good idea to re-partitions the disk to get rid of
any bogus bit, format the partition and copy back the data then.

What is the most reasonable setup here:
GPT without any hybrid magic and ext4 because it is so common?
Any other, possible more robust configuration, which is also
common with rescue tools and -distributions?

I have to say it once again: Thank you very much for solving
the hassle puzzle! :)

Cheers!

Hi Wol,

thank you for the link! I have installed mdadm (its on portage) but I
have not used it, since there is another soultion for this, which I
tried first. 

Andrea posted this wonderful line:

mount -o ro,offset=512 /dev/sdb /mnt/xxx

which mounts the filesystem by skipping the partitiontable completly.

Currently I am rescueing the data. If all is safed, I will tru
mdadm...

Thank you very much for your help!

As soon as there are more information, I will report back.
Maybe this can also help others with similiar problems.

I had booted into my old system, attached the disks and both show the
same behaviour: Only the device itself (/dev/sdb) was recognized.

'file' shows the following output:

file sdb-data
sdb-data: Linux rev 1.0 ext4 filesystem data, 
UUID=2f063705-0d3a-4790-9203-1b4edab7788c (extents) (64bit) (large files) (huge 
files)

Looks better than I have thought...or?

I will take a deeper look tommorrow...I am too tired to
"fix partition tables manually" this evening!

Read you tommorrow! :)

Hi Andreas,

thank you very much for your analysis! :)

when doing a gdisk -l /dev/sdb I get this Rocky Horror Picture Show:

I have two external disks of that kind, same product, nearly the same

Three weeks ago...about...guessed...with my old system.
Because these were backup disks I *NEVER* touch them with
any partitioning tool whatsoever...

It is complete unknown to me, what could have destroyed the
partitioning...

YES! These drives were used as backup and as backup of the backup. I
NEVER touched them with any partitioning tool after I had put a
filesystem and data on it.

Windows? no thank you...all my windows here are transparent and
open,.. ;)
Joke aside..
No Windows (tm) here. The disks are used only with my Linux box using
ext4 as filesystem.

With my new PC (my old MBR-based system was 12 years old and needed to
be replaced. My kernel became "GPT aware onlu with my new PC.
Everything before was based on MBR.

My new PC can read GPT disks...my system is based on it.

I copied the first 230GB of that disk to an empty partition of my new
system and run "testdisk" on itafter the analysis it came back
with "this partition cannot be recovered" but did not sau. whether the
reason is a partition table, which is broken beyond repair, or simply
due to the incomplete image file...

Hi Wol,

thank you for your posting! :)

I switched to my new PC around 31.3.2020...
so there is no change "over the years" involved here...I think.
Where in the kernel this update is made?
I cannot remember to have configured such a thing manually...

Changing the partitiontable in any way is risky to the data 
I think...I am very unsure to do this.

I have access to an old kernel / system and can boot it.

But than I have the same problem another way around: I can
no longer access my new system ... due to the different 
sector size

Are there any other ways to fix this problem?

Cheers!

[gentoo-user] Trouble with backup harddisks

[tuxic]

Hi,

recently I switched from the old MBR-scheme to GPT on
my new PC.

I have two external USB-harddisk, which were partioned/formatted with
a MBR-scheme/MSDOS partition (but were never used to boot from. They are pure
data containers).

When I connect these to my new PC, only the device is shown:
/dev/sdb, /dev/sdc.

The kernel is configured (beside other things) as follows:

#
# Partition Types
#
CONFIG_PARTITION_ADVANCED=y
# CONFIG_ACORN_PARTITION is not set
# CONFIG_AIX_PARTITION is not set
# CONFIG_OSF_PARTITION is not set
# CONFIG_AMIGA_PARTITION is not set
# CONFIG_ATARI_PARTITION is not set
# CONFIG_MAC_PARTITION is not set
CONFIG_MSDOS_PARTITION=y
# CONFIG_BSD_DISKLABEL is not set
# CONFIG_MINIX_SUBPARTITION is not set
# CONFIG_SOLARIS_X86_PARTITION is not set
# CONFIG_UNIXWARE_DISKLABEL is not set
# CONFIG_LDM_PARTITION is not set
# CONFIG_SGI_PARTITION is not set
# CONFIG_ULTRIX_PARTITION is not set
# CONFIG_SUN_PARTITION is not set
# CONFIG_KARMA_PARTITION is not set
CONFIG_EFI_PARTITION=y
# CONFIG_SYSV68_PARTITION is not set
# CONFIG_CMDLINE_PARTITION is not set
# end of Partition Types

CONFIG_BLOCK_COMPAT=y
CONFIG_BLK_MQ_PCI=y
CONFIG_BLK_MQ_VIRTIO=y
CONFIG_BLK_PM=y

dmesg shows this:
[14617.672363] usb 2-2: New USB device found, idVendor=1058, idProduct=25a2,

[14619.748918] ...ready

I tried different USB ports in a desperate hope of success...
...no, same problem.

Interestingly fdisk shows the following:

host> sudo fdisk -l /dev/sdb
Disk /dev/sdb: 931.49 GiB, 1000170586112 bytes, 1953458176 sectors
Disk model: Elements 25A2   
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x16f2a91f

Device Boot StartEndSectors   Size Id Type
/dev/sdb1   1 1953458175 1953458175 931.5G ee GPT

The type is shown as GPT...but the drive has a MSDOS partition table.

Reading my (old) internal harddrive with an external USB docking
station is possible without any problems, though.

Unfortunatelu I have no space for 1T image of that drive -- otherwise
I would have made an image copy and experiment with that.

So better ask, than sorry ;)

Is this fixable or did I lost my backups?

Hi John,

what graphicscard you want depends heavily on what you want to
do with your PC...
What are the tasks, which put a heavy load on your PC/graphicscard and
which you are do regularily?
Do you do a lot of rendering (Blender for example) or video
(re-)encoding? Do you AI related things (tesorflow for example)?
Or is gaming you main application?

Furthermore: You CPU must fit your graphicscard performancewise.
It makes no sense to choose "a performance beast" and to combine
it with a "entry level being".
The fastest graphicscard can onlu as fast, as data are coming from
the CPU and vice versa.

On the internet you find a combination of the Ryzen 5 3600 with
one of the nvidia RTX 20[678] SUPER cards. The RTX 2060 SUPER
comes with 8GByte of video ram instead of 6 GBYte of the RTX 2060.

"Linus Tech Tipps" and "Tom's Hardware" are probablu to look for.

HTH!

Hi Peter,

Hi Kent,

Thank yopu very much for your research and your explanations! :)

Due to some statements I found online I did a interesting little
experiment:

fstrim
fstrim
reboot
fstrim 

Reported amount of data for each fstrim:
200.2GiB
  0.0GiB
--
200.2GiB

The reboot seems to be worth the same amount of fstrimmed
data as one week of daily updates and recompilations. ;)

(By the way: This all happens on a ext4 filesystem).

Background according to the reports I found online:

The kernel is keep track of all, which already has been fstrimmed and
avoids to retrimm the same data.
This knowledge gets lost, when the PC is powercycled or rebooted.

I think, the value of the amount of fstrimmed data does not reflect
the amount of data, which gets physically fstrimmed by the SSD
controller.

The kernel onlu throw the information of "possible candidates for
being fstrimmed" towards the SSD controller, which is real master
behind all this.

And as you wrote: The maximum amount of "possible data for being
fstrimmed" is all free space of the filesystem.

Slightly related: 
Do you know the purpose of this value (smartctl -a ):
Data Units Read:656,599 [336 GB]
Data Units Written: 702,251 [359 GB]
Host Read Commands: 4,316,042
Host Write Commands:3,080,180

Are these the raw amount of data, I have send to the SSD?
Looks like a lot...

Hi Rich,

thanks for the explanations again.
But I think it is better not to implement a feature at all as via
printf.

For a dry run I had expected, that some checks had been implemented,
whether a non-dry run would be successfull.

For example:
When submitting 

fstrim -n /

as normal user I get:
/: 0 B (dry run) trimmed

Doing the same without dry run set I get:
fstrim: /: FITRIM ioctl failed: Operation not permitted

When doing a 

fstrim -n /home/user

as normal user, I get the same behaviour as above --
despite that /home/user is on a harddisk with no
fstrim functionality at all.

If fstrim cannot implement the above correctlu, it would
be better not to implement it all...I think.

Cheers!

Hi Rich, 

thanks for explanation.

My observations does not fit with your explanation, though.

Early in the morning I did a fstrim, which results in the
200GiB of freed data.

Base on you posting I did a fstrim now with no
wait in between:

host:/root>fstrim -v /
/: 3.3 GiB (3578650624 bytes) trimmed
host:/root>fstrim -v /
/: 0 B (0 bytes) trimmed

This time the first fstrim reports a small mount of trimmed
data and second one no fstrimmed data at all.

The SSD is a 
ADATA Technology Co., Ltd. XPG SX8200 Pro PCIe Gen3x4 M.2 2280 Solid State 
Drive (rev 03)
(cut'n'paste from `lspci`)

host:/root>df -h /
Filesystem  Size  Used Avail Use% Mounted on
/dev/root   246G   45G  189G  20% /

Hi Alan,

NOW I am no longer feel alone with all my fstrim/SSD related
questions! :)

I exactly fall over this before.

It looks like fstrim would take its "dry run" really seriously
and does NOTHING - it even does not communicate with the SSD.
Therefore there is no responds from the SSD how much has been
trimmed...or "0 bytes" in other words.

If you start it with no "dry run", it will send the the SSD
informations, what parts, which still keep data, can be freed,
because this data is no longer linked to anything.

Fstrimming "does harm" ;) in the first place. It will cause
some kind of writing, which is -- in the purest sense of
the word -- "bad" to the SSD. 

But fstrimming is good for the SSD in the more global context, since
all freed blocks now are available for wear leveling to the SSD
controller again.

I cannot say anything in the context of LVM, since I 
don't use it.

But I don't *think* (read: don't know for sure), that
it would harm, since you are dealing with data, which
already has been flagged for "can be overwritte" by
the filesystem.

Since the SSD controller handles chunks of data one
level lower (the controller does not know anything
about filesystems), fstrim tells it, which data
can be overwritten from the filesystems point 
of view.

BUT: Any undelete operation is made impossible
after a fstrim.

Some inside view to the status of the ssd can be taken
by this command:

sudo smartctl -a 

This command only reads from the SSD.

[gentoo-user] "Amount" of fstrim? (curiosity driven, no paranoia :)

[tuxic]

Hi,

jyst out of curiosity:

I have a 512 MB NVMe SDD drive installed, which I had (currently)
formatted with one 256 MB root partition.
I bound /var and /tmp to hardisk.

Currently I am doing one Gentoo update a day and I am running
unstable.

Just to get a feeling, how often I need to fstrim / I do it
currently by hand once in a week.

Fstrim reports about 200 GiB of trimmed data.

>From the gut this looks quite a lot -- the whole
partition is 256 GB in size.

Smartclt report for the drive:
Data Units Written: 700,841 [358 GB]

Each week 200 GiB fstrimmed data for a partition of
256 GB in size and since the beginning I have written
only 358 GB to it.

How does this all fit together?

Cheers!

[gentoo-user] new hd: Security / hdparm / differences

[tuxic]

Hi,

In my system there is a 3T Winchester digital blue 

Model Number:   WDC WD30EZRZ-00GXCB0
Firmware Revision:  80.00A80


I bougth a second one for backyp purposes

Model Number:   WDC WD30EZRZ-00Z5HB0
Firmware Revision:  80.00A80

Looks pretty simiiar to me...

The first one is in use for a month or so, I received
the second one just two hours ago.

I want to disable the security feature and the spindown-if-idle
feature of the second drive as I did with the first.

First step was to compare the output of 'hdparm -I ' of the
first with that of the second one.

Differences ( I will skip identical parts ):

First:
Standards:
Used: unknown (minor revision code 0x006d) 
Supported: 10 9 8 7 6 5 
Likely used: 10

Second:
Standards:
Supported: 9 8 7 6 5 
Likely used: 9



First:
Formfactor 3.5inch

Second:
Not mentioned

First
Commands/features:
Enabled Supported:
   *DMA Setup Auto-Activate optimization
Device-initiated interface power management
   *Software settings preservation
unknown 206[12] (vendor specific)
unknown 206[13] (vendor specific)
   *DOWNLOAD MICROCODE DMA command
   *WRITE BUFFER DMA command
   *READ BUFFER DMA command

Second:
Commands/features:
Enabled Supported:
DMA Setup Auto-Activate optimization
   *SCT Write Same (AC2)
   *SCT Features Control (AC4)
   *SCT Data Tables (AC5)
unknown 206[12] (vendor specific)
unknown 206[13] (vendor specific)
unknown 206[14] (vendor specific)



"DMA Setup Ayto-Activate optimization" is enable for the first drive,
for second one it is not. The section about this feature in the
manpage says "use with extreme caytion" and I cannot decide, whether
that what is written there is still valid or some sort of cry
from the past.

I am unsure about to think about these differences...?

The second thing are the security settings. I want drives with no
security settings and no way to manipulate them without user
interaction. I want these settings stored in the drive instead
of setting them at each boot since the second drive will be
temporarily used in a docking station "past boot".

The current security settings for both drives are:
not enabled
not locked
frozen
not expired: security count
supported: enhanced erase

(I have frozen the settings for the second drive just a minute ago and
it will forget the settings (going "not frozen" then) as soon I switch
the docking station off and on again.)

If I remember correctly I did this for the frsit drive with:
freeze security setting
lock security settings

and I did this without using any password.

On the second drive "freeze" works as exspected, but "lock"
wants a password.

After startpageing for a while I found a site with "Master passwords
for some drives"...and I am unsure of what I have found there
(reliability-wise ... it was not via the TOR network, though... ;)

Currently there are no data on the second drive. So accidentally
wiping it off doesn't matter as long the drive remains intact.

I would prefer to have both drives in the same state.
I didn't changed any DMA-related settings for the first drive by the
way.

How should I handle the DMA differences between the frist and the
second drive?

How can I handle the security issue with the second drive?

Cheers!

Hi,

I /thought/ that /etc/portage/package.mask is a file and using it

Also the docs are of that opinion, too:

Hi Mark,

thanks for the links!

for the first I want to avoid propietary / closed software if
possible.

The problem, which I tried to mention in my initial post was, that
alsamixer displays a control for pcm volume only. I also reffered
to the suggestion to run alsamixer -D equal, which fails on my
side - which was the reason for my initial posting.

I need a equaliser, which -- as said -- processes the audio data
and implements the equaliser functionality by itsself.

Cheers!

[gentoo-user] Audio Equalizer for a DAC ?

[tuxic]

Hi,

Finally I got a FIIO E10K DAC running with my Gentoo Linux and ALSA.

Alsamixer displays a volume slider for PCM only. I can play several
audio sources - so far so nice.

Then I installed media-plugins/alsaequal, which installs fine.

I changed my .asoundrc to:

ctl.equal {
type equal;
}

pcm.plugequal {
type equal;
slave.pcm "plughw:0,0";
}

pcm.equal {
type plug;
slave.pcm plugequal;
}

(alsamixer displays the DAC as soundcard 0 - I have deactivated the
audio of the motherboard via BIOS settings) 


Starting for example 'alsamixer -D equal' results in an error:

ALSA lib 
/var/tmp/portage/media-libs/alsa-lib-1.2.2/work/alsa-lib-1.2.2/src/control/control.c:1379:(snd_ctl_open_noupdate)
 Invalid CTL equal
cannot open mixer: No such file or directory
[1]5304 exit 1 alsamixer -D equal

...seems logical to me, since I have only a volume slider in
alsamixer.

The FIIO establishes this USB device:

Bus 005 Device 002: ID 1852:7022 GYROCOM C Co., LTD DigiHug USB Audio


Does anyone on this list uses a FIIO E10K / E10 with Linux and got
more than a simple PCM/volume slider with alsamixer ?

Is there any equaliser software available, which processes the audio
data instead?

Is my configuration still incomplete?

Cheers!

Normally I do a cleanup after each upgrade/compilation/install like
so:


emerge --selective=n  @preserved-rebuild && emerge --depclean -va && 
eclean-dist -C -d -v && eix-test-obsolete

which removes 

virtual/w3m

then. Next upgrade, which looks liek:

eix-sync ; emerge --update --newuse --deep --with-bdeps=y --tree 
--keep-going --backtrack=30 -v --verbose-conflicts -1 @world

it installs 

virtual/w3m

again.

And so on.

How can I stop this?
Are the commands I use fishy?
What is the reason of this loop -- other parts of the system will not
be reinstalled over and over again ?

Hi,

ssh catches the tty so no password will be shown (but processed).

What happens if you paste the password, ignore, that "nothing" happens

Hi Rich,

these [CENSORED] filenames are mainly copies from the contents of
usbstick, which were previoysly filled using machines, which were
neither UNICES nor Linuxxes nor MacOSxxes ... you know what I mean.
I myself stick to sane filenames. 

Detox is known to me. But for certain reasons I cannot change the
filenames now...I have to process them first.

Hi Neil,

is this the "Bothwick effect" ?

This was the first I tried after my script failed...and it failed
again after adding the "".
I tried it again...and now it works. 
Only difference: I did it from the commandline (using zsh).

I am baffled.

But it is better, I don't completely understand, whu it is working
now than vice versa ;)

[gentoo-user] Question about handling filenames with "illegal" characters...

[tuxic]

Hi,

a loop like this

for fn in asd* ; do
do_something $fn
done

fails, when a file is named like this:

List of OSses allowing spaces in filenames.txt

.

Normally I would replace the asd* with the according

find . -name 'asd*' -print0 | 

but I got in trpuble, because "do_something" 
now misunderstood the whole thing.

Is there a way to express $fn in a way, so that
do_something get one filename at a time and
whole thing does not is torn apart by some
not so nice filenames?

Hi Ian,

I only switched the kernel. Anything else remains the same. I will

[gentoo-user] Sudden case fan problems by switching to new kernel...

[tuxic]

Hi,

The configuration for kernel 5.6.3. (vanilla) works fine.for me.
Then I changed to kernel 5.6.4 using the same configuration.

Suddenlu the fan at the back of my PC case never stops from
rotating at its highest speed.
Changing back to kernel 5.6.3. and the problem is gone.

On the internet I found one report of a fan problem after
an upgrade of Ubuntu...but that was 5 years ago...

I compared the entries in /sys/devices/platform/nct6775.2592/hwmon/hwmon1/*
between the two kernels but found nothing obvious.

The CPU temperature was around 45° C in both cases.

Waiting does not help also...
(in case kinda 'settling time' has changed...or so...)

Is there any other place to investigate?
What could be the root of this?

Cheers!

Hi all,

thanks **a lot** for all this great information! :)

Since I have a NVMe drive on a M.2 socket I would
be interested at what level/stage (?word? ...sorry...) 
the data go a different path as with the classical sata
SSDs.

Is this just "protocol" or there is something different?
On the internet I read, that the io-scheduler is choosen 
differentlu by the kernel, if there is a NVMe driven detected,
for example.
(I think, the io-scheduler has nothing to do with the fstrim
operation itsself (I think...) -- it is there only as an example...)

I think, due to the corona lockdown I have to fstrim my hair
myself  :) 8)

Hi Rich, hi Michael,

THAT is information I like...now I start(!) to understand the "inner
mechanics" of fstrim...thank you very much!!! :::)))

One quesion -- not to express any doubt of what you wrote Rich, but onlu
to check, whether I understand that detail or not:

Fstrim "allows" the drive to trim ittself. The actual "trimming" is
done by the drive ittself without any interaction from the outside
of the SSD.

For me (due my beginners level of knowing the "behind the scene"
things) this is kinda contradictionous.

On the one hand, the SSD drive keeps track of the information, what
blocks are used and unused. And trimming is done by the drive in
itsself. On the other hand trimming is "just giving the drive more
information about"

What kind of information does the commandline tool fstrim transfers to
the SSD beside the command "fstrim yourself" (an ioctl, I think?),
which is needed to fstrim the blocks and what kind of information is
the SDD collecting itsself for this purpose?

Hi Michael,

thank you for replying to my questions! :)

My question are more driven by curiousty than by anxiety...

...but it neither explains why to do so nor does it explain the technical
background.

For example it saus:
"For most desktop and server systems a sufficient trimming frequency  is
once  a week."

...but why is this ok to do so? Are all PCs made equal? Are all
use cases are equal? It even does not distinguish between SSD/Sata 
and SSD/NVMe(M2 in my case).

These are the points, where my curiousty kicks in and I am starting
to ask questions.

For example: Take an SSD with 300 GB user-useable space. To
over-overprovisioning the device the user decides to partitioning
only the half of the disk and format it. The rest is left untouched in
"nowhere land".
Now the controller has a lot of space to shuffle data around.
Fstrim only works on the mounted part of the SSD. So the used blocks
in "nowhere land" remain...unfstrimmed?

To not to use all available space for the partitions is a hint I found
online...and then I asked me the question above...

If what I read online is wrong my assumptions are wrong...which
isn't reassuring either.

Unused blocks with data cannot be used for wearleveling. Suppose you
have a total amount of 100 block, 50 blocks are used, 25 are unused
and empty, 25 are unused and filled with former data.

In this case only 25 blocks are available to spread the next write
operation.

After fstrim 50 blocks would be available again and the same amount of
writes could now be spread over 50 sectors.

At least that is what I read online...

Performance is not my concern (at least in the moment ;) ). I try to
fully understand the mechanisms here, since what I read online is not
without contradictions...

To technically overthink problems is a vital part of my profession and exactly 
what
I am asked for. I cannot put this behaviour down so easily. :)
