How to change this....

[Álvaro Castillo]

Dear OLPC Fedora list,

I wanna know.... how to change display manager? So, I have installed XFCE,
So, on Sugar environment only I can change to GNOME or back to Sugar. How
change this?

Note, I find How to install XFCE on OLPC and maintain it here URL.
http://wiki.laptop.org/go/XFCE#GDM_.28gnome_display_manager.29

Problem is systemd is not using initab... need update these section.

Other thing is...
How I can assign root password for ever. For example. I do sudo passwd
root. Set password OK. However, I run su - and run to # without request any
password. So... is dangerous...

and how to setup user to ask what user I am interested to login. And not
only login olpc user. Any ideas?

Thanks!

We write a small file in /home/olpc , called ".olpc-active-desktop" .
I assume xfce ships a /usr/bin/xfce-session program, if that's the
case, write "xfce" to .olpc-active-desktop , then restart.

Remove the user olpc from the wheel group.

I don't know that part off the top of my head, sorry. You'll want to
install gdm there, and have prefdm start gdm instead of olpc-session.

I documented some of the things you might want to do in a blog post.
It's also covers setting up gdm and from there you should be able to
get XFCE

The following will allow you to set a root password.
sudo su -
passwd

Whether or not a user is prompted for a password when using sudo is
set in /etc/sudoers and it's well documented in that file. The
associated user also needs to be in the wheel group.

Follow the above blog post and then you can just add users per a
normal Fedora instance.
