Description
Created attachment 130115 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 (closed)-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
Below is found in syslog.
