<pre>I have a Dell Ultrabook E7440 using one of the Dell ePort docking stations with
dual DVI outputs on it.
Periodically my screen will reset, almost like the resolution was changed. This
only happens on the 2 monitors connected via DVI. the Xorg logs do not show any
relevant information.
I upgraded to kernel 3.19.0-rc2 when the issue started occuring. I was
originally running an older kernel that did not natively support both monitors.
I had to use a modified libXinrama to span the display across both monitors.
Now, with 3.19, both monitors are properly detected, but this reset is rather
annoying.
I believe this may be related to this bug:

Let me know what information needs to be provided to look into this.</pre>
