have been running Trusty just fine since it was released for testing..
so yesterday for some stooooopid reason I thot I would install gnome-
sessions-flashback just to try it out..
it seemed to install without any problems/errors and when I rebooted
I got to the Ubuntu log-in screen & was presented with 3 choices:
1.) Gnome Fallback with Compiz
2.) Gnome Fallback with METACITY
3.) Ubuntu Classic
However no matter which choice I use it appears to log-in, leaves the
log-in screen, but then loops right back to the log-in screen....appears
to not accept my password 
never get any error messages, it just keeps looping back to log-in screen
I have tried going to recovery mode with no luck
Code:
sudo service lightdm restart
has no effect either 
am running out of ideas...
right now I would be happy just to get back to having Unity working....NEVER
thot I would say that !!!
any help to get back to working greatly appreciated !!!

luckily my Ubuntu 12.04.4 & Mint 16 distros still work
