problems reaching the lightdm screen to login

Hello

 

I am a Ubuntu Linux user who prefers the light-weigth LXDE interface hence Lubuntu. While on my server I run Ubuntu server version. If I install centrifydc and then join the AD domain I can then install lubuntu over the top and all is well.

 

If one attempt this in the wrong order it fails and one is tempted to remove the installed centrifydc it is no longer possible to get back to the Lightdm login screen. However it is possible to login in a character mode Ctrl-Alt-F1 way.

 

Having done this on one major machine I am now locked out of all my GUI applications and a re-install would cause MAJOR heartache. So what I am in need of is advice and guidance to recover from this failed install/removal of centrifyfdc package.

 

It appears to methat on other deskop only machines one hast install Ubuntu desktop install centrifydc join domain and then install lubuntu-deskup. It ios a bit of a pain but one can expect centrify to support/ test every combination of distros.

 

Also asking in https://ubuntuforums.org/showthread.php?t=2348906

@Neill_R1,

 

Welcome back.

 

I think there's a misalignment of expectations or a confusion here.

 

Lubuntu is an independent Linux distribution currently not officially supported by Centrify Express

This means that we don't actively test our software and utilities like installers, CLI utilities and add-ons.

The Express download page explicitly names the distributions and versions supported by Centrify.

Since Lubuntu is a Debian derivative, it is possible to install CentrifyDC, however at that point you are on your own the same way our software works with newer OS versions.

For example.  Today (1/9/16) I read that Red Hat has made available the beta version of RHEL 6.9.  Although it's possible for our software to "just work" if Red Hat did not make major changes, users are still on their own.   We have an SLA of 6 months to provide full support.

 

You should go to th e Idea Exchange and request that we add support for the platform, however only a significant number of commercial customers moves the needle when new platform support is considered.

A big example is different OSs using the POWER8 little endian.   We had many commercial customers request support for it and we are adding these in Suite 2017.

 

I hope this clarifies the confusion.  As always we are here to help and open to feedback.

Re: problems reaching the lightdm screen to login

There is no misalignment of expectations here. What am after is to returning my system to a working system (GUI) with out centrifydc. I know that if I install ubuntu then add centrifydc I can join a domain and then install Lubuntu-desktop and it works.

 

However I stupidly did it in the wrong order and now can not get back my GUI.

 

P.S.

I am writing this on a ubuntu-server with Lubuntu-desktop and I can log in as an active directory use if I so wish.

I am trying to understand how to channel things here.

 

Forget about Lubuntu/LightXDE for a moment.

 

Are you having issues with stock Ubuntu (the OS/GUI combination that we test and officially support)?

Re: problems reaching the lightdm screen to login

I have not tested ubuntu-desktop version as yet as i have said ubuntu-server non gui  + centrifydc added works. Lubuntu-desktop on top also works.

 

I don't want to forget about Lubuntu because it is the distro I choose because it is light weight. I hate (dislike) Unity desktop.

 

As I keep saying I wish to recover another system and return to a working Lubuntu desktop once centrifydc is removed.  At present the boot  process does not get to the lightdm screen to log in.

Gaining GUI access to that machine is a MAJOR requirement.  The system in question is an HP G61 system running Ubuntu-server 14.04.

 

I am googling and trying things to get the lubuntu-desktop to be restored so the the lightdm login screen with appear again centrifydc has been removed

Re: problems reaching the lightdm screen to login

As the HPG61, problem machine, has ubuntu server OS and I used tasksel to remove lubuntu-desktop components. I thought why not reinstall centrify

so

 

sudo dpkg -i centrifydc-5.3.1-deb7-x86_64.deb
sudo adjoin -w i-surname.tld
sudo apt-get install ubuntu-desktop

Now I have a GUI screen but the desktop-manager is not working?  So the failed installation has hangovers I need to remove. I f only I knew what they were.

Re: problems reaching the lightdm screen to login

please advise me Is Ubuntu 16.04.1 Desktop supported and is it only the Unity windows system that is supported?
