Comment 7 for bug 1543133

It's not bug 1526658 and not bug 1536662.

I moved the files in /var/log/lightdm and .cache/upstart somewhere else and after logging in the screen doesn't stay black, but after some quick flickering I'm back to the lightdm screen. I have to restart lightdm before I can even log back into the regular unity7 session. No crash files available.
