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 Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1658185 Title: nouveau occasionally won't come back from DPMS suspend/off Status in xserver-xorg-video-nouveau package in Ubuntu: New Bug description: On several occasions over the past few months, I've moved my mouse or pressed a key to wake my monitor from power saving, but the monitor never leaves power saving.
