Comment 9 for bug 1583624

The root cause is the fd that pipe gives to USC is 0. The compositor starts and begins drawing frames, and lightdm eventually tries writing to fd=0 (also known as STDIN) which causes an Opperation not permitted error (see lp:1590447). I wrote a nasty patch that forces lightdm to keep obtaining file descriptors until fd[0]!=0 and it solved all the (known) issues that we are seeing.

 Mterry and I are workin on a fix for this ^^ and I'll work on the log name issue right after. I think we can close this bug, as the original issue has long since been resolved. Thanks.
