i figured out how to get past the login screen issue on my attempt after much research and a bit o luck. it turns out the error was caused by permissions error on the /tmp directory. this is easliy resolved by logging into tty1 via ctrl+alt+F1 and logging in through the terminal. from there use the following command : chmod ug+rwx, o+rwt /tmp
after that ctrl+alt+F7 and attempt to login normally...
ive still got some more testing to do before i begin putting together a more formal how to on the procedure.
not all processes start durring boot up due to permission issues a little help tracking down these stragglers would be nice ... so far i know the postgresql service fails on startup due do permision denied for a server.key file....or somesuch file....
