the new display Manager of Linux Mint, MDM, Can be easily installed on Ubuntu after adding the corresponding PPA. MDM is a fork of version 2.20 of GDM and is fully compatible with the themes for this that can be obtained over the web (at least the latest version, 1.0.6).
per to Install MDM in Ubuntu 12.10 | just follow the steps below.
Note: Installing MDM will automatically uninstall GDM – due to conflicts between the two tools – and consequently GNOME Shell – as it depends on GDM. So it is very important do not install MDM on Ubuntu 12.10 if we use GNOME Shell.
The first is to add the necessary repository:
sudo add-apt-repository ppa:nilarimogard/webupd8
We refresh the local information:
sudo apt-get update
I We install the necessary packages:
sudo apt-get install mdm mint-mdm-themes
Then we simply choose which Display Manager we want to use, which we will be asked to configure immediately after installing MDM.
To customize MDM, with themes for example, just launch from the Dash -or our favorite menu- the configuration module of the access screen (Window ID).
