I would add here that it's hard to test the issue in other desktop
environments since, at least for me, Unity was the only that worked with
the DisplayLink device I have (AOC e1649Fwu). I'm currently using a
slightly tweaked version of this script[1] to enable the display, and

I have similar problems using xrandr on a laptop with a dual display LCD
32" TV under Ubuntu 14.04 with Kernel's 3.13.24, 3.13.29, 3.15.1,
3.15.2, 3.15.3, 3.15.4 and 3.15.5. A new Kernel seems to come out each
week addressing various problems so I have held off reporting the
glitches.

It's improved, but still present. It's most obvious when moving the mouse
around because the cursor blinks slightly. There was definitely improvement
and it's useable now, although refresh artifacts remain.

I also have this problem, but the funny thing is, if I maximize any
window on the display link monitor, the issue of choppy mouse movements
goes away. I will clarify that dragging a window around is still
choppy, but not nearly as bad.. I even tried setting the background
color to 'black' thinking

So apport-collect didn't work since I'm not the reporter. Instead of
submitting a new bug, let me know the best way to attach what is needed
to this bug. Thanks.

I can confirm that I am seeing the same behavior when using a USB
DisplayLink monitor and Unity. I upgraded to a mainline kernel of 3.12
to get it working, and see the flashing mouse and slow graphics
behavior. uname -a output is:

Daniel Défago, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an

release of Ubuntu? ISO images are available from

FWIW, you can work around the problem by using e.g. XFCE instead of
unity.

The issue here is that compiz prefers pageflips (quite rightly for igfx)
which for udl means that we need to push the entire display over the
slow usb link (and requiring a slow readback) on each update (instead of
just the damaged region) -- a write magnification issue.
