Hello,
Indeed the solution #108 of matorres124 worked for me. (The arrowmouse
doesn't flicker anymore on the top area of my middle screen.
However one verry verry annoying bug remains ! When I have one window that I
want to drag and drop in another screen, if I am not fast enough,
it gets stucked in between,
and then the 2 concerned screens start to flicker on their whole area
+ their opened windows start to intermitently slightly resize themselves,
while I cannot click anywhere anymore.
Then the only solution I have found to stop this terrible thing is terrible as
well, I spam ctrl+alt+f4 to close this stucked window...
I tried to do as in the post #109 of wajuzdonny but it seems that for me
this step is useless.
My config is :
- About the graphic card, typing
$ lspci -vnn | grep -A 12 '\''[030[02]\]' | grep -Ei "lay|kernel"
in the terminal gives me this answer :
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] Thames [Radeon HD 7500M/7600M Series] [1002:6840] (prog-if 00 [VGA
controller])
Kernel driver in use: radeon
Kernel modules: radeon
- about the wiring : the original laptop screen + 2 additional samsung 22"
USBplugged. So I have one USBhub, linked to 2 displaylink USB3.0toHDMI devices
(and passive HDMI male to DVI female adapters).
- about the orientation : one samsung on the left with portrait orientation,
one on the other side with normal landscape orientation.
Also this is a much less major issue but when I boot with this config
all my desktop shortcut go on the left screen... Would you know why?
By thanking you.

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.
