First of all I am new to the world of Ubuntu, it is pretty much my first time using it, ever.
The system seems to be running very stable, but I have run across one weird problem that I'm not quite sure what's the cause of.
Whenever I use the Ubuntu Software Center, after a few seconds of use (this can vary a bit, but it is usually not long), my laptop enters a black screen, and then after a few seconds enters the Ubuntu startup screen where you log in, almost as if the entire OS restarted.
I would love to provide debug information but I'm not quite sure how to, so if there's anything that could help please ask and I will edit the question with additional details :)
Thank you all for the help!
I have now added the dmesg log output. It can be found here: DMESG Log Output
[EDIT] - Hardware Details
I am running Ubuntu on an intel-based Mac, more specifically MacBook 8,1.
