Thanks for the advise. There is no kern.0.log, but kern.log.1, maybe you meant xorg.0.log (all attached)
Just had two complete freezes with an updated kernel linux- image-4.8.0-56-generic 4.8.0-56.61~16.04.1 amd64. Switch to console and REISUB didn't work thus hard shutdown. I've booted with 4.8.0-54 and no freeze since one hour. ** Attachment added: "gpu-manager.log" https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1655348/+attachment/4899511/+files/gpu-manager.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1655348 Title: gpu-manager Error: can't open /lib/modules/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1655348/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
