Installed Kali on xubuntu and login menu disappeard then these errors

[shan]

I am new to Xubuntu/Ubuntu, running Xubuntu on a Macbook Pro 2009 15"

Installed Kali linux on Xubuntu, and running into these errors.
 Login script keeps looping, so tried this
sudo apt-get update
sudo apt-get -y dist-upgrade
sudo -apt-get install fglrx

because someone suggested it's due to Nvidia issue, didn't fix the issue
