I have recently upgraded from Ubuntu 16.04 (Unity) to 18.04 (GNOME 3).

I am trying to recover some Unity features I enjoy, such as switching between windows with just scrolling the mouse wheel over the app icon on the launcher or Ubuntu dock, making a sort of Alt+Tab effect, and if there are several windows for a same application (e.g. several .pdf opened at once), it switches between them (sort of Alt+œ effect).

I have been mentioned the

$ gsettings set org.gnome.shell.extensions.dash-to-dock scroll-action 'cycle-windows'

command, but it has basically no effect on my computer. I just get

GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings will not be saved or shared with other applications.

which I don't really understand. I was told to install dash-to-dock and to run

sudo apt install dconf-gsettings-backend

but it did not change anything (to me) either (dconf-gsettings-backend was already installed).

Fyi, I also tried, since it is in the same vein, to run

gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize'

I get the same output as above, and it does not seem to do anything either.


Additional information: As suggested, I tried

user@xxx : /etc/ld.so.conf.d$ ls
cuda-9-0.conf  fakeroot-x86_64-linux-gnu.conf  i386-linux-gnu.conf  libc.conf  x86_64-linux-gnu.conf  zz_i386-biarch-compat.conf

I also tried:

$ which gsettings
/home/user/anaconda3/bin/gsettings

Hope this helps :)

  • I have seen this but since it is quite old I wasn't sure it was relevant. Plus, I don't understand much of what the OP answer, and I don't get similar results, thus I don't know how to apply the fix proposed. (see edited question) I also run which gsettings, as suggested by 2nd answer, and got /home/user/anaconda3/bin/gsettings, I guess this is an interesting point, but I am not knowledgeable about PATH and comments suggest to not mess with it. – Hoetre Oct 3 '18 at 12:17
  • I obtain error: 0-5:unknown keyword it appears that I have no /org/ repo at the root level. – Hoetre Oct 3 '18 at 13:25
  • It works, answer accepted ! Thank you very much ! – Hoetre Oct 4 '18 at 13:11

If you're having trouble with gsettings try using dconf command instead. For example, in place of

gsettings set org.gnome.shell.extensions.dash-to-dock scroll-action 'cycle-windows'

run

dconf write /org/gnome/shell/extensions/dash-to-dock/scroll-action "'cycle-windows'"
