I have installed Ubuntu on my HP n11-6TU laptop. I originally installed
15.04 and it may have frozen once or twice while running that version. I
did notice that under high load I would see artifacts on the external
(HDMI) monitor, like momentary diagonal streaks across the screen.
I upgraded to 15.10 when it was released and started to experience semi
regular hangs of the system these hangs would happen once every couple
of hours of use and seemed to be related to video updates. For example
it would happen when I scrolled in a web browser, and would rarely
happen when I was working on code or when the system was idle. The hangs
happen both when using the built in monitor or the external monitor.
When the system hangs the screen remains static. The mouse does not
move. The system does not respond to any keyboard or mouse input from
built in or external devices. The system does not respond to a ping or
any other type of attempted network connection.
The only way I can find to recover the system is to hold the power
button down until the power is switched off, and then to power it on
again.
I will attach my dmesg output. If there is anything else I can try
please let me know.
