Ubuntu GNOME 13.10 cannot change window border theme

I installed Ubuntu Gnome 13.10 and when I change GTK theme using Gnome Tweak Tool, only theme of widgets changes, theme of Window border remains same.

Can somebody help me to fix this issue ?

Solution 1:

To change to theme Adwaita, open a terminal and do:

gsettings set org.gnome.desktop.wm.preferences theme Adwaita

Solution 2:

Thanks to the solution linked by user62716: https://bbs.archlinux.org/viewtopic.php?id=167309, let me type it out here.

cd /usr/share/pyshared/gtweak/
sudo gedit gsettings.py

Insert this before line 37:

if schema_name == "org.gnome.desktop.wm.preferences":
    schema_filename = schema_name + ".gschema.xml"

Now it should look like:

def __init__(self, schema_name, schema_dir=None, schema_filename=None, **options):
    if not schema_dir:
        schema_dir = gtweak.GSETTINGS_SCHEMA_DIR
    if schema_name == "org.gnome.desktop.wm.preferences":
        schema_filename = schema_name + ".gschema.xml"
    if not schema_filename:
        schema_filename = schema_name + ".gschema.xml"

Save, and exit. Open Tweak Tool, go to "Theme", and for "Current theme", select your desired theme.
