same here, when monitor is plugged in I mouse coursor is flickering on
host display, additionally sometimes sites do not work correctly when on
screen 2, coursor is flickering too (but much less).
When I've tried to apply solution from #108 after the reboot the second
monitor was not detected at all, I had to revert back my settings.

My issues is, after adding a 3rd monitor to Ubuntu 14.04, the mouse
flickers (or blinks) when the cursor is on monitors one or two, but
not 3.
Monitor 1: 1440 x 900 - Laptop's Native Monitor
Monitor 2: 1920 x 1080 - Laptop's HDMI Port's External Monitor
Monitor 3: 1024 x 768 - SIIG USB 2.0 to VGA Pro Monitor
Here's the video card that feeds my laptop's native monitor, monitor 2
(hdmi).

00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset

The 3rd Monitor is powered through a Display Link certified SIIG USB
2.0 to VGA Pro adapter (A2H1320X1374 - not sure what this number, but
it is a sticker on back of the device):

Additionally, unity-control-center crashes sometimes after I "Restore
previous settings", after selecting a resolution too high. This
freezed my laptop, requiring a hard reboot.
