I have a very strange problem with a recently purchased ViewSonic 4k display
connected via display port to a Thinkpad 410 with nvidia gt218m (nvs 3100m).

Every time the mouse pointer touches the left edge of the screen, the display
becomes a block of solid color and freezes. Suspend/resume of the laptop
reanimates the display.

versions: X server 1.17.2, linux kernel 4.5.0, nouveau 1.0.11 and 1.0.12, dual
screens active (also happens with external monitor active only, though that
configuration is very unstable), does not matter if the external monitor is
configured as "left", "right" or "top" to the internal; did not try "bottom".
System: ubuntu 14.04, linux kernel from mainline ppa, x-server & co is of
lts-wily variant.

with workaround: xbarrier 1 0 1 2160, so pointer can't go to column 0,
everything seems stable.
