How can I enable the GTK3 header bars on Ubuntu 16.04?
You can enable that by creating new file
sudo nano /etc/profile.d/csd.sh
That contains
export GTK_CSD=1 export XDG_CURRENT_DESKTOP=Unity:GNOME #export GTK_THEME=Ambiance #export GTK_THEME=Adwaita:dark
Logout/Login
Reference: for the new colon format Unity:GNOME
. https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1554878

Tests:
Bharadwaj Raju's solution is the best for now
Using
/etc/profile..
export XDG_CURRENT_DESKTOP=GNOME
gnome-software OK, gnome-calculator OK, nautilus OK (black sharp corners, get smaller if killed then launched again), unity-control-center FAIL (No components, should run with
XDG_CURRENT_DESKTOP=Unity
)Mine (See above):
gnome-software NO, gnome-calculator NO, nautilus OK (black sharp corners, get smaller if killed then launched again they go), unity-control-center NO.
Another try with
export XDG_CURRENT_DESKTOP=""
gnome-software OK, gnome-calculator OK, nautilus FAIL, unity-control-center FAIL.
For specific GTK3 apps
Edit their .desktop
file (Nautilus' is located at /usr/share/applications/nautilus.desktop
)
And add env XDG_CURRENT_DESKTOP=GNOME
just after each Exec=
line. For example, nautilus.desktop
's Exec=
line(s) (It has two, one for opening a new window) will change from...
Exec=nautilus --new-window %U
[… Some other lines, skipping …]
Exec=nautilus --new-window
to
Exec=env XDG_CURRENT_DESKTOP=GNOME nautilus --new-window %U
[… Some other lines, skipping …]
Exec=env XDG_CURRENT_DESKTOP=GNOME nautilus --new-window
NOTE: If you use Unity, do the same to /usr/share/applications/nautilus-autostart.desktop
and/or /etc/xdg/autostart/nautilus-autostart.desktop
.
(You may have to logout/login.)
For all GTK3 apps
Word of warning: Telling all apps that the DE is GNOME may result in side effects.
Edit: Unity fails to start with this.
Edit ~/.profile
and add a line:
export XDG_CURRENT_DESKTOP=GNOME
then all apps will obey this.
