error

I have been bearing this issue for a few months already. My two monitors system
would randomly freeze up, mainly forcing a hard reset to resolve, though there
are a few times it would recover by itself after freezing for 20 seconds.
During a freeze, the display would turn black for most of the time. Sometimes,
it would just log me out. It can take place as soon as 30 seconds from logging
in.

I tried out LiveCD of (dev) Tails 2.11, Ubuntu 17.04 and I am able to use the
system for the whole day without freezing up.

My "uname -a" is below:

Linux home 4.10.0-9-generic #11-Ubuntu SMP Mon Feb 20 13:47:35 UTC 2017 x86_64
x86_64 x86_64 GNU/Linux

and my "xserver-xorg-video-intel" is 2:2.99.917+git20160706-1ubuntu1
