Complete Lock Up, where to start?
I had something odd happen yesterday and its the second time its happened to me, I figured the first time was a fluke, both times it's occurred I was using Gnome shell. Basically the system completely freezes up no keyboard to touch pad no nothing, basically I end up having to force a power down and restart by holding down the power key.
Where do I begin to trouble shoot this issue, what log files should I take a peek at? I really don't even know where to begin with this one.
I feel I should mention this as it could be related every once in a while I'll get a blank screen, or my open windows will reload, again this only seems to happen while using Gnome shell. It's as if it gets confused as to what it supposed to be displaying but then quickly figures it out puts everything right.
What I'm dealin' with:
HP Pavilion G6-1D60US, dual booted: Ubuntu 14.04 64bit, & Windows 7 Home Premium 64bit, 640 gig HDD, 4 gig RAM
