My UBUNTU 16.04 is freezing and restarting the session. This is always happening while I'm using LibreOffice 5.1.6.2.
I found this using DMESG:

Which makes me think It is having some GUI problems, which is weird it only happens while I'm using LibreOffice, while I'm programming (Qt creator) or using the chrome, there is no session's reboot.
Can it be my Integrated graphic card? there is any way to know what is happening with LibreOffice to understand why is freezing the PC and make it restart the session?
