[Message part 1 (text/plain, inline)]

Hi,

I've noticed surprising behavior on a fresh install of GuixSD v0.10.0
when using XFCE.  In XFCE, in the "Appearance" section of the settings,
under the "Style" tab, if you select an alternate style (e.g.,
"Xfce-kolors"), the color scheme does not actually get updated.  I
expected the colors of the windows to change, but they did not.

Is this expected?  Perhaps I'm missing something that needs to be done
to apply the change, but it seems like it just isn't working.

Currently GTK themes installed outside ~/.themes aren't found. There's a few
patches on the mailing list waiting review from a month or so ago.

Here’s what worked for me:

* install gnome-themes-standard into the system profile
* set GTK_DATA_PREFIX to “/run/current-system/profile”

The problem here is that GTK_DATA_PREFIX is not a list of directories in
which GTK+ should look for themes; it is just a single directory.  We
need to patch GTK+ to search through a list of directories instead.

Can it be arranged for these two things to be done automatically in the
installation image?  I think it would be simple to add
"gnome-themes-standard" to the sample desktop.scm file we provide, but
I'm not sure how we would ensure that GTK_DATA_PREFIX gets set up
correctly.  Is there a mechanism in GuixSD for adding such environment
variables to /etc/profile, for example?

Definitely.

I’ve tested that with this patch changing colors under the “Style” tab
in Xfce does have an effect.

I’ll commit it shortly if there are no objections.

Thanks!

This fixed the issue for me.  Thanks!

I heavily disagree with this approach for two reasons:

1) It doesn't work with user theme installs.
2) I have a patch that fixes this problem completely.
3) The fix I provided has been duplicated upstream in GTK+.

I suggest reverting this and applying my patch and read the full breakdown of
the issue and solution here:

https://lists.gnu.org/archive/html/guix-devel/2016-03/msg00492.html

This was the patch I suggested earlier but seem to be ignored or missed.

Jookia.

Oh!  Thank you for the link.  Ludo, what do you think about Jookia's
comments?

Right, it’s mostly a hack to fix the immediate issue, which probably
covers many use cases since ‘xfce-desktop-service’ and
‘gnome-desktop-service’ install things globally.

Oh, I had overlooked this one, sorry about that!

Ricardo raised some concerns in that thread, namely that the patch
hard-codes a specific profile name as well.  Did you have a chance to
look into it?

Thanks for the heads-up, and my apologies for overlooking it!

The patch I linked has no hardcoding (it's PATCHv2), it uses XDG_DATA_DIRS.

No problem.
