Hello Guix!

I tried to add (service colord-service) to my config and I got a
error back :-(. I reduced my system to the minimum but the problem is
persist.

Here's the backtrace I get with the colord-system.scm config attached:

```

Do you know what's going on?

And now attached with the correct mime type... sorry! :-)

Oh, I just realized (colord-service) is in %desktop-services
already... ooops my bad!

In gnome's settings it tells me that there are no devices that can be
colour managed, I had assumed that was because colord was missing from
the config but that's probably not it. Is it working for other people?
If so it's probably just my hardware (ThinkPad x220).

Sorry for the noise!

I think it is not able to manage devices because the Argyll CMS dependency 
[0] is missing in Guix. Unfortunately, it seems to also depend on the 
discontinued Jam build tool [1], so there is a little bit of work to be 
done.

I did spot another issue with colord since the recent core-updates merge: 
https://issues.guix.gnu.org/issue/37843 It seems like it is no longer 
being started automatically via dbus?

Hope that helps,
Jack

Indeed, stracing dbus-daemon while going to the GNOME settings panel,
“Color” tag, I see:

--8<---------------cut here---------------start------------->8---
459   sendmsg(48, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="l\3\1\1\213\0\0\0\3\0\0\0m\0\0\0\6\1s\0\5\0\0\0:1.95\0\0\0\4\1s\0'\0\0\0org.freedesktop.DBus.Error.AccessDenied\0\5\1u\0\2\0\0\0\10\1g\0\1s\0\0\7\1s\0\24\0\0\0org.freedesktop.DBus\0\0\0\0", iov_len=128}, {iov_base="\206\0\0\0Connection \":1.95\" is not allowed to own the service \"org.freedesktop.ColorManager\" due to security policies in the configuration file\0", iov_len=139}], msg_iovlen=2, msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL <unfinished ...>
--8<---------------cut here---------------end--------------->8---

So something somewhere is unhappy.

I diff’d the ‘org.freedesktop.color.policy’ files of colord 1.4.3 and
1.4.4 and there are no functional differences.

Commit 33f9778bc83086837b99e5c5e99cd514cb0d154e fixes this and colord
now starts correctly again.

I believe that should also fix the “night light” feature in GNOME.  I
tested it in a VM but it was hard to tell if it was working.

Could you confirm, Jack?

Thanks,
Ludo’.

I can confirm it's working for me on GNOME on my thinkpad! I can use the
night light settings and the laptop screen was detected in the "Color"
section of the settings. And I can see the colord daemon is running.

This is awesome, thank you!

Marking 37911 as done, I'll let Jack close 37843 if he's happy with it.

Probably related to my recent colord update to fix simple-scan. 
I'll take a look.

Thanks!
