David, by any chance, are you running VMware Workstation when these problems happen?
My computer has similar symptoms, and when I ssh in, VMware Workstation seems to be in an odd state. I can't suspend my VMs from the command line (in preparation for a reboot of the host). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1658185 Title: nouveau occasionally won't come back from DPMS suspend/off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1658185/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
