Thanks for the quick help, everyone! I had tried google before, but
obviously not using the right keywords...

As described in the bug report, installing libnvidia-ptxjitcompiler has
fixed things for me.

Pascal, Istvan: Thanks for your input, too! But I had it running
before the upgrade, including the ICD for OpenCL.

Cheers

Quick question: how do I raise a ticket on Redmine? Have looked around 
the website and it's not obvious


Thanks

Just to be very clear.

You want darktable to NOT APPLY any printer ICC.
   => this is possible

You want darktable to NOT DISABLE the CUPS color management.
   => this is not currently supported

This way you can send your image to CUPS with a queue using a specific
RIP to get proper color.

Is that what you want?

If so please open a ticket on our redmine with this conclusion and
assign it to me.

We have two options (at least for now):

1. Add a check-box to allow CUPS color management

2. Or do not disable CUPS color management when no printer profile is
specified.

Maybe 2 is just what we want...

Tobias, how does that sounds?

[darktable-user] OpenCL trouble, NVidia driver 367.44 "could not create context"

[Michael Below]

Hi,

today I did the upgrade to the nvidia driver version 367.44, coming
from 361.xx

After the upgrade, darktable can't enable OpenCL anymore, it says it
"could not create context for device", whatever that means.

Any ideas what to do?

I am running darktable 2.06 on Debian testing.

Cheers
Michael

I quote Ivanov. The behaviour of 1-key could be confusing and error prone.
An example when it fails: let's say I have multiple pictures selected.
some starred 1 and other starred 0. When I press 1 the rating is reverted :(


The colour tag works different. When multiple picture are seleted, first
key set color tag to all selected images (does not erase already selected).
Next key will erase all colour tags.

I think the best is to have coherence, and latter example (tag colour)
is what I prefer.

just my2c
