[Pkg-systemd-maintainers] Bug#741861: libsystemd-login0: Cannot login, must first restart lightdm from tty1

[Kyle Bentley]

Package: libsystemd-login0
Version: 204-7
Severity: normal

Dear Maintainer,

As of 2014/03/15 (+/- 1) I cannot login to Jessie normally. From a cold boot 
I get to lightdm, however, after entering credentials nothing happens.  The 
screen isn't stuck, I can still move mouse, get to tty prompts, ect.... It's 
just that I never reach a dekstop.  To remedy the situation, I have to first 
switch to tty1, login as root, and run 'service lightdm restart'. After this 
I am able login as a normal user, but there are a few side effects that make 
this unpleasent.  I can no longer restart, poweroff, or suspend as a normal 
user, as was the case before.
