I just attempted an upgrade from 14.10 to 15.04, the upgrade completed and i get as far as the login screen but when i input my password the screen blacks out flashes a bunch of text that i haven't been able to read yet and takes me back to the login screen. Can someone help me fix this issue or instruct me as to how i can find more information about it. A cursory google search has yielded nothing so far. Many thanks in advanced and i'm sorry i have no more information than this i am not well versed in the more advanced applications of ubuntu.

I think I have similar problem to yours: Ubuntu 15.04. Problem booting with systemd
If that's the case in bootloader's select screen select line Advanced Options for Ubuntu
and then load option with upstart
.
If that works you can set upstart
as your default service manager: https://wiki.ubuntu.com/SystemdForUpstartUsers#Permanent_switch_back_to_upstart
