That sounds strange, can't speculate without darktable-cmstest output.
That being said, i only know that geeqie does do color management,
but i don't know about gnome image viewer.

Ok, so I set the method to get the color profile in darktable to "xatom" 
(inspired
by the fact that darktable-cmstest gave the correct profile for xatom 
but not colord.
Now geeqie shows the same colors with "system color profile" as 
darktable does with

system color profile.

Gnome image viewer show more saturated colors, but I guess it's not 
color managed,

so that can't be fixed?

I enabled color management in firefox and installed the color profile
following http://cameratico.com/guides/firefox-color-management/
(i think after enabling icc v4 it automatically picked up on it anyway).

So now I think it's consistent everywhere except for the 
non-colormanaged applications,

which is the best I could hope for, right?

I had a similar problem. Everything looked good on my local devices, but 
images in Google Photos came back looking washed out. The problem went 
away after I set display profile and export file format to sRGB (web safe).

Thank you for your quick reply Roman!

Here's the output of darktable-cmstest:

-> %  darktable-cmstest
darktable-cmstest version 2.2.5
this executable was built with colord support enabled
darktable itself was built with colord support enabled

couldn't locate primary CRTC!

Better check your system setup
 - some monitors reported different profiles
You may experience inconsistent color rendition between color managed

I also did

 colormgr get-devices


as I understood that would give me the settings of colord?

That is correct.

Is your browser color-managed? Most likely not. Also, are you sure the
website does not simply discard the color profile info from the JPG?

This is why the output color profile setting should stay at the default (sRGB).


However, if I set darktable's display profile to "Adobe RGB", the exported

the web and geeqie with color management set to the system profile.
It looks
different on the gnome image viewer,

So i guess it does not do color management. Not a huge surprise.


Given that my main goal is to publish on the web, that's the workflow I'm
using now, but it seems rather strange
to me to set the darktable's display profile to a different profile. Is that
the correct workflow?
And is there a way to make the colors show the same way in the gnome image
viewer?

[Brune Wayce]

Hello,
as you can find here "
https://www.mail-archive.com/darktable-user@lists.darktable.org/msg03683.html;
I had a similar problem.
In the end I bought a 1050ti (Asus EX-GTX 1050 TI-4G) and I'm pretty happy
with the final performance result.

My box:
cpu: intel i5-3450
ram: 8gb
sda: SSD Samsung 830 128GB 2,5"
sdb: Western Digital Caviar Green 2TB 3.5"
video card: NVidia 1050ti 4GB
os: debian 9 (stable)
proprietary driver version: 375.82
darktable: version 2.2.5

I've run the proposed test:

and here are my result:

(11,640 CPU)
without OpenCl: [dev_process_export] pixel pipeline processing took 28,074

Hope this helps.

I did not expect to work with different versions (ppa vs. repository

After installing the ppa version on PC, I observed the expected  behavior.

Thank you all together!

That is the problem. You simply can't take sidecar from newer version
and use it with older version. It might work in some cases, in some
cases you will be having subtle data loss, like in that case.
If you load that sidecar in older darktable, it will even warn you about that.

I can guarantee that with 100% certainty.

the databases change between versions and are not guaranteed backware
compatible.  most probably where your problem arrises.

why don't you match dt version (to the latest) between boxes and then use
*only* the library.db/data.db from one box?

ps: when describing a problem, you would help yourself by providing *all*
pertinent data, ie: op system, pgm ver, ...

By the way, I'm using different versions (PC: 2.0.3, LP: 2.2.5), but the
behaviour should be the same. Does somebody knows for sure that this
cause the problem?

Re: [darktable-user] sidecar handling

I just checked the differences of the XMP files:

(1) When I close darktable at LP this XMP file is written:



 http://www.w3.org/1999/02/22-rdf-syntax-ns#;>
  http://ns.adobe.com/xap/1.0/;
    xmlns:xmpMM="http://ns.adobe.com/xap/1.0/mm/;
    xmlns:darktable="http://darktable.sf.net/;
   xmp:Rating="5"
   xmpMM:DerivedFrom="DSC1630.JPG"
   darktable:xmp_version="2"
   darktable:raw_params="0"
   darktable:auto_presets_applied="1"
   darktable:history_end="1">
   
    
   
   
    
   
   
    
   
   
    
   
   
    
   
   
    
   
   
    
   
   
    
 
 
    
   
  
 



(2) By choosing the 'reload XMP' in the dialoge I get only two differences:

   darktable:xmp_version="2"  >     darktable:xmp_version="1"

   new lines between    
       
       
    
 2
    
   
   
    
 0
    
   
   
    
 monochrome
    
   
   
    
 0040
    
   
   
    
 gz12eJxjYGBgkGAAgRNODESDBnsIHll8ANNSGQM=
    
   
   
    
 7
    
   
   
    
 0
    
   
   
    
  
    
   

  and    


(3) By choosing the 'overwrite XMP' in the dialoge I get only three
differences:

the first two are the same like in (2)

the third is:   
darktable:params="9891cc3f8f1e9e410040"  >   
darktable:params="0040"


Please note that in all versions the monochrome mode is enabled (this
was my criteria to observe the changes). However I do not understand,
when the database and when the XMP files will be used.


I hope this information help you to reduce/identify the problem.

I confirm that the modification time changes when modifications are
applied.

Disclaimer: Pure speculation.
If DT uses timestamps to evaluate whether a sidecar file has changed
since last run and if the two computeres involved does not have a
synchronized clock in general and more specific between the two changes
could be lost.

[darktable-user] sidecar handling

[Sebastian Pfeifer]

Dear users,

imagine the following situation: I have two computers in my LAN, call
them PC and LP. If I am working on LP, I usually mount the releated
folder structure with my photographs from PC via sshfs. Recently I was
working on my LP and switched to PC later, but I could not manage to see
the modifications on PC I previously did on LP.

I already set the core preference 'look for updated xmp files on
startup' on enabled, but neither 'reload selected XMP-files' nor
'overwrite selected XMP-files' resulted in the desired behaviour.

Thanks for your help!

Sebastian
