Title: Login screen in Ubermix?
Post by: ginlodge on May 03, 2014, 03:02:58 PM

We have (we think) successfully joined an Ubermix laptop to our Active Directory domain.  But, I cannot seem to find any way to have a login screen show up when the machine starts up.  It just starts to the regular Launchpad.  How can we get a login screen to show up so that we can test if AD users can log in?

You'll need to remove the autologin entries from /etc/lightdm/lightdm.conf . Can do by opening a terminal and 'sudo gedit /etc/lightdm/lightdm.conf'

Weellll. I tried it.
Removed both autologin entries from the lightdm.conf (autologin-user=user and autologin-user-timeout=0)and added "greeter-show-manual-login=true". 
Saved. Restarted, and at startup it just goes into some strange mode where the screen is black/grey/black/grey... with the white mouse pointer the only thing showing, an endless loop. 
Have to restore it to get back in.
Also tried removing another entry - user-session=une-efl and got the same behavior.

I tried to attach a screen shot of what is displayed at startup after restore, but attachments do not seem to work.

I am sure I am missing something and I am a total newbie in Linux but want so badly to use Ubermix at the school where I work.

OK, go to System Settings:User Accounts or, if you don't see that, open a terminal and type 'gnome-control-center user-accounts'. Turn off Automatic Login there and see if it works better.

Should I also remove it from lightdm.conf?

Seems like you might have installed the simple updates, which makes that tool invisible. Open a terminal and 'sudo rm -rf /usr/local/share/applications/gnome-user-accounts-panel.desktop' then look for 'User Accounts' in System Settings

Unfortunately, it is still not there.  Would you recommend that I go back to a fresh install?  Will I need to install centrify again?

Try the terminal command from a few entries ago first, and if you still see an error, then yes, I would reinstall using option 1 (ie do not install simple updates). Then unset auto login in system settings and install centrify.
