Theme is not affecting Client Side Decoration of HeaderBar? #636

Closed luxe closed 7 years ago

luxe commented 7 years ago

Once installing the theme, I noticed that it was only affecting some of the Ubuntu windows. It seems that applications have their own window paneling, that I am unable to change through the theme.

For example:

Notice how gedit has the default Ubuntu buttons, while the GNOME file manager is using the applied numix theme:

theme

Is there a way I can get gedit and other applications to match my existing theme?
I want all the windows to look the same.

Reading more into it, I found a relevant post:
http://stackoverflow.com/questions/28650646/what-is-client-side-decoration However, I have been unable to fix the problem.
Looking at other screenshots from issues in this project, I can see that this isn't a problem for other users.
Any thoughts on what I can do?

Additional info:
I am on Ubuntu 16.04 LTS, and have gone to the gnome-flashback. I'm also using the gnome-tweak-tool to apply the GTK+ theme.
It seems that I'm on GTK 3.0 (at least that's what I'm changing in the numix theme to see relevant changes).

That's strange. Actually gedit is one of the apps the Ubuntu folks patched so as not to use client-side decorations. The gedit window is actually server-side decorated. Nautilus (GNOME Files) is another one they patched so I wonder why it does use CSDs (a headerbar) in your screenshot.

Anyway, have you got some other themes installed in order to check whether it is a Numix-only issue?

I've tried some other themes now (Adwaita, HighContrast, Orion, Radiance).
They all have the same problem. I suppose its something to do with my ubuntu configuration, although this is a fresh install with minimal changes made.

Are most applications suppose to inherit changes from the theme?
Most of my applications do not:
gnome-terminal, firefox, calculator, dconf-editor, to name a few.

Programs that are changing seem to be:
file-manager, gnome-tweak-tool, syslog

I'm no expert in Ubuntu questions so I'm at a loss as to why that's happening. However from what you tell the theme is only applied to CSD apps.

Can you fire up dconf-editor and navigate to /org/gnome/desktop/wm/preferences/ and look up what's the value for theme? Same for /org/gnome/desktop/interface and the value for gtk-theme?

Under org.gnome.desktop.wm.preferences, the attribute states
DEPRECATED: This key is deprecated and ignored.

It was set to Adwaita, but changing it to Numix had no effect, so I assume it is indeed being ignored. The property at org.gnome.desktop.interface gtk-theme, and it already set to Numix.
The gnome-tweak-tool is changing that property.

I finally found the problem:
org.gnome.metacity.theme was not being set.
I'm not sure how to change this property without doing it through the editor manually, but changing it to Numix has adjusted all my remaining windows.

These are the two places it seems I needed to apply the theme for it to affect all the windows: 

gsettings set org.gnome.desktop.interface gtk-theme 'Numix';
gsettings set org.gnome.metacity 'Numix';

Thank you for your help.

Ah OK, so that's a general issue with gnome-tweak-tool not being able to change the metacity theme (which in turn is only relevant for the gnome-flashback session which GNOME doesn't officially support).
