Enable guest account on MX 19 or Debian

By default on debian there is no guest account provided by the lightdm package, but you can install it as follows:
Code: Select all
wget -c https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/lightdm/1.22.0-0ubuntu2.1/lightdm_1.22.0-0ubuntu2.1.tar.gz
tar -xvzf lightdm_1.22.0-0ubuntu2.1.tar.gz
mv lightdm-1.22.0/debian/guest-account.sh /usr/sbin/guest-account
chown root:root /usr/sbin/guest-account
chmod 755 /usr/sbin/guest-account
mkdir -p /usr/share/lightdm/guest-session/skel/
mv lightdm-1.22.0/debian/guest-session-setup.sh /usr/share/lightdm/guest-session/setup.sh
chown -R root:root /usr/share/lightdm
chmod 755 /usr/share/lightdm/guest-session/setup.sh
Then you modify the lightdm configuration file
and you uncomment these lines and change the value like under
Code: Select all
greeter-hide-users=false
greeter-allow-guest=true
allow-guest=true
Now you can reboot!!!!
If you want a more customized guest session, you can first create a real user:
Don’t forget to replace username with the user name that you want to create:
You will be prompted to set and confirm the new user password.
(optional) you can add the user you created to the sudo group to have sudo access.
Using a special user account for setting the guest preferences is the most convenient way to customize the guest session feature.
Log in to the user account just created and change things to what you want your guests encounter at startup.
Now we create a symbolic link to the home directory of the user account "username":
Code: Select all
sudo mkdir /etc/guest-session
sudo ln -s /home/username /etc/guest-session/skel
Now, when you launch a guest session, it will have the same preferences as you set for the user account. As you can see on the attachments, the only difference is that on the guest session, any changes done here will be deleted on logout or reboot.

I would suggest not posting advice to install Ubuntu packages.

Where in my post you see installation of ubuntu package or installation of a package.
I just extract debian script files (lightdm-1.22.0/debian/) from the package.

Yes, but what is in Ubuntu's guest-account.sh? Is there a reason why it is not included in Debian?

I am not a developper but i know that ubuntu is also based on debian. That's why we can pull out the scripts from (and you are right) an ubuntu package but inside a debian folder "lightdm-1.22.0/debian/". Just for fun.
I don't know why it is not included by default in debian but each OS has his policies.

What's the difference between a "guest account" created with all that hassle and one for a user named "guest" that I can create in three seconds with MX User?

If you check his new additions to his first post, he is referring to the ability of the "guest" account to not save anything done within, so it's always vanilla when accessed again.
...when you launch a guest session, it will have the same preferences as you set for the user account. As you can see on the attachments, the only difference is that on the guest session, any changes done here will be deleted on logout or reboot.
That's probably the script at work, the one he extracted from the Ubuntu package. I have no idea if the same thing can be found in some separate package in Debian.
I've used this before long ago, when I had elementaryOS 12.04 on my old PC. It was enabled by default. But ultimately I chose to disable it by editing the lightdm.conf file. I didn't even know that this functionality supposedly doesn't even exist (even as a disabled option) in Debian.
Of course, using MX User, various group access and permissions are very easily enabled/disabled using checkboxes. No need for the usermod command he set out in his first post. But can the whole session and all changes be wiped upon logout or reboot in Debian without the need to import that whole script? Maybe just some commands are needed?
Hmm. That might be something to consider adding to MX User.
