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
v3.13.11.6-trusty 13-Aug-2014 and before is OK
v3.13.11.7-trusty 18-Sep-2014 and after has the ERROR
after 3.13 upstream 3.14.25-031425-generic has the ERROR
upstream 3.18.0-031800rc5-generic has the ERROR
Reinstalling a formerly purged NON-upstream Ubuntu kernel, and investigating
the release date of the kernel packages, I could verify, that the critical
kernel change step is exactly at the correspondig point.
3.13.0-36-generic 04-Sep-2014 and before is OK
3.13.0-37-generic 25-Sep-2014 and after has the ERROR
3.16.0-24-generic ... has the ERROR
All of these kernels were tested with the SAME Ubuntu 14.10 systems, and the
only difference between them was that wich kernel is booted. In case of
Ubuntu 14.04 I had the critical point EXACTLY at this same place.

Intalling upstream v3.13.11.7-trusty kernel, I catched the folowing
error:
Running depmod.
depmod: ERROR: Module 'hci_vhci' has devname (vhci) but lacks
major and minor information. Ignoring.
update-initramfs: deferring update (hook will be called later)
(3)
Trying out two dozens of different kernels, now I can give a bit better
description of the nature of the graphic error depending on kernel version.
3/a: except for few cases, the keyboard shortcuts work, they can invoke
programs assigned to them, ... naturally I can not use them, because I can
not see them.
3/b: almost alway the option to go Ctrl-Alt-F1 and apply Ctrl-Alt-Del is
alive, while almost never can I read anything even on the caracter terminal,
... except for the case, if the crash of the graphic view arrives a bit (few
seconds) later, and I have a narrow time slot to escape to the character
consoles.
3/c: if the crash is later, then it is exactly when I first move the
mouse.
3/d: I left the most important experinece to the end:
the graphical view crash has four different states, the middle two of them
are new views for me, due to the new kernels I tried out:
-1- as if an oldtimer CRT was not able to correctly position the
horisontal sync, and hence the picture is horisontally rotated, and
this state is different from all the other erratic state in that I
can invoke and use graphical programs, hard to use, because of the
rotation: going rightward out I arrive and enter at the left edge
-2- as if an oldtimer CRT can not catch at all an inappropriate
horisontal sync, far beyond its frequency limit
-3- the essentially almost homogenous white view is patched of
very small very intesively blinking regions
-4- at the top a very few lines reflect the original content of the top
unity line, but the rest is white and STILL, no blinking, ... let us
mention, that my background is white, but NOTHING can occur in this
area, this is a dead white area
Originally an immediate or soon -4-, and immediate or soon -1- soon -4- were
the typical scenarios.
Trying out additional kernels, the additional possibilities are: inmediate
or soon -3-, and immediate or soon -1- soon -2- soon -3-.
Perhaps I should draw a state transition picture.
Thanks for the help,
Peter.

Title:
kernel dependent deterministic view crash on X startup
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
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
scan lines, where one can see some sort of vibrating content.
Sometimes there is a 1-3 seconds of normal operation just at the
start, when Ctrl-Alt-F2 works, and swithing there one can work in the
character terminal forever. But as soon as the disorder in the X view
appears, even the Ctrl-Alt-F2 console change does not work visually,
however a blindly stroken Ctr-Alt-Del is correctly executed.
What I know: (1) on the core i3 based laptop there is no trace of this
kind of view crash, while in case of the Phenom x6 1100t and Radeon HD
6570 based desktop machine the problem is fully deterministic. (2)
the problem is distro independet, i.e.: I have it with Ubuntu 14.04 +
kernel 3.13.0-37-generic, and also with Ubuntu 14.10 +
3.16.0-23-generic, and I do NOT have it with Ubuntu 14.04 + kernel
3.13.0-36-generic, and also with Ubuntu 14.10 + 3.13.0-36-generic.
(3) In case of Ubuntu 14.04 in average every second or third boot gave
a 1-3 seconds of grace period when I could escape to Ctrl-Alt-F2,
while in case of Ubuntu 14.10 there is no such a short time slot when
I could escape. (4) my configuration is set to fall into my only user
account directly, I will do experiments, whether the problem is there,
if the startup is without falling into an account.
If I can, I will apport log files with produced with the
3.16.0-23-generic kernel as well, not only with the 3.13.0-36-generic.
I try to send the remaining information after my work day, now I have to
leave, sorry.
