Log-in and Shut-down window presentations

I used GParted to resize the partition of ZorinOS 6.1 and moved it as well. All went okay and Zorin is working flawlessly.
However, the Log-in and Shut-down window presentations have changed. Instead displaying the "blue" screen with the 'Z' and rotating wheel in the Log-in window a 'running bar' at the bottom of the Log-in window is shown and a 'black, text-based' window is shown when the Logging-out.
I kindly request guidance to reinstate the original Zorin 6 Log-in/Log-out windows.
TIA

Computer Information:
ZorinOS 6.1 is installed on internal 1tb HDD (multi-boot)
Other Operating Systems installed: WinXP-Pro, LMDE 201204, Kubuntu 12.04.1
Type: Desktop

Architecture: x86_64

Thanks for response.
Is it possible to reinstate the original Log-in/Log-out presentations?

I am sure this was the cause as this wasn't an issue prior moving/resizing.

You could try:

Code:

sudo apt-get update && sudo apt-get dist-upgrade

Done, all okay.

sudo apt-get update grub

This didn't work...
E: The update command takes no arguments

Be sure you are connected to internet and choose to Boot Zorin in safe graphics/recovery mode - usually 2nd item in Zorin GRUB menu, and once there select 'dpkg' to check for the possibility of broken packages and their repair.

Followed and implemented your instructions but the issue remains.

You know, since the distro is working more than satisfactory I really can live without having the original "ZorinOS" log-in/log-our screens showing. And just wait until a new version (or major upgrade) is available or alternatively may reinstall ZorinOS. Cheers...
