    hard lockups... maybe once a day... ?

    I'm getting sporadic hard lockups -- no mouse, no responsiveness at all, can't ssh in, etc. Happens maybe once a day or so. Sometimes screens go black, sometimes they just freeze. No high fan usage or anything, just a freeze. No option but to cut power.

    Any ideas? I'm using nvidia drivers (GeForce GTX 1060, 560.35.03) and three monitors. Graphics drivers were my first guess -- what would be the best first step to debug this? What's the easiest way to roll back driver versions?

    journal shows nothing in the logs around the time of the freezes.

    Have you tried the Magic Key Sequence? Alt+Prt sc+REISUB

    If that doesn't safely shutdown and reboot your PC, then a hard restart, as you are using now. But always try the Magic Key Sequence before resorting to that.

      Oh nice, for some reason I didn't think REISUB was still around. I'll try it next time.

      I have downgraded to v535 (using software sources "additional drivers" tab) and will see how that goes...
