Yes, actuall that was the way, how I used my main computer when 14.04 was in
use:
namely I had the both of 3.13.0-37-generic and 3.13.0-36-generic there
in 14.04, and I made my daily work using 3.13.0-36-generic, and
sometimes booting into 3.13.0-37-generic I checked whether the problem
went
(1)
Getting help how to make tests with upstream kernels, I did find the step,
where using NONE of the few kernels BEFORE that point I have NO xorg error,
while using ANY of the few kernels AFTER that point I HAVE xorg error.
before 3.13 upstream 3.12.33-031233-generic has NO error
The new 3.16.0-25-generic has the bug as well.

Title:
kernel dependent deterministic view crash on X startup
Status in “linux”
** Description changed:
kernel 3.13.0-37 and 3.16.0-23, but not kernel 3.13.0-36
The phenomenon: just when the user interface starts at the end of the
Ununtu startup, the screen reamins in one solid color (very light grey,
this is the everage of my colors), except for the topmost 3-4
The kernel 3.13.11-03131106-generic_3.13.11-03131106.201412021942_amd64

During the installation there was a message: Running depmod.
depmod: ERROR: Module 'hci_vhci' has devname (vhci) but lacks major and minor
information. Ignoring.
To be sure, I
The kernel you prepared me replaced the 3.13.11-03131106-generic kernel
you gave me before.
This new version DOES *NOT* WORK, it shows exactly the same visual and
functional phenomenon, collapse.
Looking forward to the next test,
Péter.

I have just tested the specially prepared 3.13.11-03131106-generic
kernel you gave me,
and the usual error IS THERE. Using the last few new kernels, the
typical scenario is this:
(1) the correct picture is there for 1 or at most 2 seconds
(2) then the view is wraps around, asif
Good news: the latest version DOES WORK, I use it to make this comment.

You received this bug notification because you are a member of Kernel

The kernel you sent me recently, replaced the existing Utopic kernel 3.16.0-28,
if I understood correctly this was a normal behaviour due to the identical
version numbers, ... anyways:
NONE OF the original 3.16.0-28 kernel and the fresh kernel you sent me
works,
I see exactly the same crash
Due to your careful question, it turned out, that I have made very serious
error!
When installing your Utopic test kernel with commit b47f210 reverted
I did not install the linux-image-extra...
I tried to check whether I did same kind of error earlier.
In case of 3.13.0-36-generic,
Few roadmap questions.
Do I guess correctly, that the appropriate upstream kernel should work,
since the kernel you gave me with the patch from upstream worked, in
early January?
Is there a way to test, how can I test directly an upstream kernel that
it really works in my case? Or it is more
I have just tried the kernel
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-rc7-vivid/
released three days ago, and it WORKS!
Many tnaks,
