To activate/enable all extensions every time at startup:

1. Create a folder for your own scripts:

   
   
   

   mkdir ~/bin




2. Create a script file: gnome-shell-enable-all-extensions.sh:

   
   
   

   nano ~/bin/gnome-shell-enable-all-extensions.sh

   
   
   

   With contents:

   
   
   

   #!/bin/bash
sleep 2s # just in case
cd ~/.local/share/gnome-shell/extensions
array=($(ls -l --time-style=long-iso | egrep '^d' | awk '{print $8}')) # get only the folder names from current path
ext_list=$(printf "'%s'," "${array[@]}") # rebuild the string
ext_list=${ext_list%,} # Remove the final character of the variable
gsettings set org.gnome.shell enabled-extensions "[${ext_list}]"





3. Setting up permissions for the script file:

   
   
   

   chmod +x ~/bin/gnome-shell-enable-all-extensions.sh




4. At last, puts the command in startup gnome-session-properties:

   
   
   

   /home/YOUR-USERNAME/bin/gnome-shell-enable-all-extensions.sh
