I guess these logs are rw user only, my system seems to work like this,
ls -al /var/log/lightdm
total 152
drwxr-xr-x 2 root root 4096 Jul 21 07:35 .
drwxrwxr-x 13 root syslog 4096 Jul 27 07:35 ..

The older gz files are rotated by logrotate but I thought
they were all world readable.
In any case the huge log files probably have repetitive error
messages that will give you some idea where it is stuck.
If /tmp is rw for you you would have to find some other reason
it can't make a lock file. In any case if you can find the repeating
error loop in the log files post that. The tails you posted I'm
not sure if they got a full cycle.
