Hi, I pushed on this ppa [1] a modified unity7 with more debugging. Can you
please:
1. $ sudo add-apt-repository ppa:azzar1/unity7-testing
2. $ sudo apt-update
3. $ sudo apt upgrade (make sure unity is updated)
4. $ unity

Lock the system, after the problem happens write somewhere at what time the
problem happened (hour and minutes please). Then send at
<email address hidden> the content of ~/.cache/upstart/unity7.log.
Please in the email specify at what time the problem happened. Thanks.
