I have a fresh install of Ubuntu 13.10 on a brand new hard disk. My computer restarts after a few minutes I open Shotwell, which every time is importing my large Pictures library (150GB). I do have 29GB of free space in my /home, where the Pictures directory resides.
I have checked other posts about log files and none seem to point me to finding the root cause of the restarts. Can someone guide me on this?
