Description mwp.junk 2017-08-07 19:23:48 UTC
Description of problem:

Machine randomly hard locks, mouse / keyboard inputs no longer work (Unable to switch VTs, etc). Hard reset is only way to recover.

Random, could happen within 15 minutes of boot or 10 hours; however, seems to happen most when in a browser, Chrome / Firefox.

Steps to Reproduce:
1. Browse the web with chrome / firefox

Actual results:

Machine hard locks and only recoverable via a hard reset

Switching to proprietary nvidia driver resolves the issue

Comment 2 Louis Santillan 2017-09-24 23:18:54 UTC
I'm getting this super frequently as well (2-10 times per day!).  I'd switch to the proprietary nvidia (which fixes it for me as well) but then gnome doesn't know how to handle driving 3 video cards with windows.  The nvidia driver makes them available (I mouse over and the old X11 disabled screen pointer) but gnome seems to refuse to put windows on them.
