In this post I am going to explain how to enable GUI root access on Debian 8. Instructions for Debian 9 a similar and can be found here. At this point I should warn you that using the root account is dangerous as you can ruin your whole system. Try to follow this guide exactly.
- First open a terminal and type su then your root password that you created when installing your Debian 8.
- Install Leafpad text editor which allows you to edit text files. Type: “apt-get install leafpad”
- Stay in root terminal and type “leafpad /etc/gdm3/daemon.conf”. This command opens the file “daemon.conf” in leafpad. Under security type “AllowRoot=true”. So your security section in the file should look like this:[security]
AllowRoot=trueOnce it looks like this save the file then exit the window.
- Stay in root terminal and type “leafpad /etc/pam.d/gdm-password”. This command opens the file “gdm-password” in leafpad. Within this file you have comment out the line containing “auth required pam_succeed_if.so user != root quiet_success” so that it looks like this
#auth required pam_succeed_if.so user != root quiet_successSave the file and exit.
- Now you should be able to login as root in you GUI Debian 8.
