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 :)
