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).
lspci | grep 'VGA\|Display'
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset
Integrated Graphics Controller (rev 07)
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset
Integrated Graphics Controller (rev 07)
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.
