Nick (q-nick), it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal: ubuntu-bug xorg

A few terminal windows, a few Firefox pages, Thunderbird, and VirtualBox (with the extension pack loaded) running one small Linux VM with 512Mb memory (very lightly loaded as it's only running bind9). I think (but don't have perfect certainty on this) that some of the crashes have happened without VirtualBox running. Also running rsync so that backuppc on a separate machine can back it up over the network (backuppc has been a real lifesaver with all the reinstallations!) After booting the system runs happily for a while then the GUI freezes. This can take a few hours or up to a day or two. You can still ssh into the system, and if you do "top" it typically shows 100% CPU load on systemd-timesync. The same happens whether I use nouveau or the proprietary nvidia driver (361) I have tried a complete reinstallation (4 times already, starting to get quite frustrating) using the proprietary drivers and NOT using the proprietary drivers and the same still happens. The most recent time was with nouveau, and Xorg.log has a number of entries like this: (EE) [mi] EQ overflowing. Additional events will be discarded until existing events are processed. (EE) (EE) Backtrace: (EE) 0: /usr/lib/xorg/Xorg (xorg_backtrace+0x4e) [0x5652cde325ce] (EE) 1: /usr/lib/xorg/Xorg (mieqEnqueue+0x253) [0x5652cde14083] (EE) 2: /usr/lib/xorg/Xorg (QueuePointerEvents+0x52) [0x5652cdcec662] (EE) 3: /usr/lib/xorg/modules/input/evdev_drv.so (0x7f31f985c000+0x61f3) [0x7f31f98621f3] (EE) 4: /usr/lib/xorg/modules/input/evdev_drv.so (0x7f31f985c000+0x6a5d) [0x7f31f9862a5d] (EE) 5: /usr/lib/xorg/Xorg (0x5652cdc80000+0x94228) [0x5652cdd14228] (EE) 6: /usr/lib/xorg/Xorg (0x5652cdc80000+0xb96f2) [0x5652cdd396f2] (EE) 7: /lib/x86_64-linux-gnu/libc.so.6 (0x7f3202cef000+0x354a0) [0x7f3202d244a0] (EE) 8: /usr/lib/xorg/Xorg (GiveUp+0x0) [0x5652cde37330] (EE) 9: /lib/x86_64-linux-gnu/libc.so.6 (0x7f3202cef000+0x354a0) [0x7f3202d244a0] (EE) 10: /lib/x86_64-linux-gnu/libc.so.6 (__select+0x13) [0x7f3202debcf3] (EE) 11: /usr/lib/xorg/Xorg (WaitForSomething+0x1d7) [0x5652cde2f307] (EE) 12: /usr/lib/xorg/Xorg (0x5652cdc80000+0x539ee) [0x5652cdcd39ee] (EE) 13: /usr/lib/xorg/Xorg (0x5652cdc80000+0x57c33) [0x5652cdcd7c33] (EE) 14: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xf0) [0x7f3202d0f830] (EE) 15: /usr/lib/xorg/Xorg (_start+0x29) [0x5652cdcc1f59] (EE) (EE) [mi] These backtraces from mieqEnqueue may point to a culprit higher up the stack.

[ 6265.543] [mi] This may be caused by a misbehaving driver monopolizing the server's resources. What cna the problem possibly be, especially as 16.04 is meant to be a stable release and an Nvidia GT710 card is hardly bleeding-edge? Help greatly appreciated!
