This question already has an answer here:
This fault has only emerged since upgrading from Ubuntu 14.04.4 to 16.04. My laptop is an Acer Aspire E13, Intel Pentium N3540 no graphics card. I am duel booting this laptop, no issues with windows suggesting it is not a hardware issue.
Specifically the fault is a freeze of Ubuntu when using unity with no obvious trigger. Once frozen no response at all can be elicited.
I originally thought this may be a flash problem as I have in the past had similar problems with flash plugins and Ubuntu/other linux distros. However purging and reinstalling does not seem to improve the situation. I have also tried a number of different browsers in an attempt to see if this effects the frequency of the fault, it doesn't seem to. I also attempted turning off hardware acceleration again no fix.
The major issue I have is that the freeze is total, there is no way to move from tty7 (unity) to tty1-6 in an attempt to read the logs and because a forced shutdown is the only way to get a response I can find no record of the fault after restart.
How can I go about debugging this fault? Has anyone seen a similar fault and know the solution?
Thanks in advance
