[Bug 1721763] Re: ubuntu is stuck with black screen and blinking cursos at top left on all shutdown or restart

[Edson T. Marques]

Yesterday I decided to do a fresh reinstallation of ubuntu on my
notebook and after having reinstalled some of the applications and
daemons I use normally, I performed one of several reboots that I
normally do in these processes.

On this particular reboot, instead of the system getting stuck on a
black screen, I was presented with a log fragment with a text-mode
animation at the beginning of the line that contained the following
message:

"[****] A stop job is runnung for LSB: ([some variable information]
[time count / 5 min])"

These "[some variable information]" alternated between 4 information:
"automatic crash report generation"
"record successful boot for GRUB"
"Speech Dispacher"
"Handless warsaw - core"

It may be that this log is hidden and presented only in some specific
situations for which I do not know the cause. But the time the shutdown
process or reboot gets stuck on the black screen is about 5 minutes ...
As occurs in the case reported above.

Title:
  ubuntu is stuck with black screen and blinking cursos at top left on
  all shutdown or restart

Status in ubuntu-meta package in Ubuntu:
  New

Bug description:
  I really do not know which package to assign this incident, please
  excuse me.

  Any way, the release candidates is near, and this problem continues to
  occur since linux kernel was updated from 4.11 to 4.12 ... and now
  with version 4.13 the problem continues.

  I noticed that this problem does not occur with my other two older
  notebooks (one Sony Vaio and the other a generic one integrated by me)
  both old notes use NVIDIA video card in versions of more than 5 years
  ago.

  My new Dell notebook has a GTX 1050 video card ... but I also do not
  know if the cause of this problem may be linked to the video card and
  the fact that Nouveau driver and linux Kernel have received recent
  implementations for compatibilities with this new NVIDIA technology.

  The fact is that Ubuntu 17.10 has potential to be distributed with
  this problem and I think this may not be interesting, so I am
  reporting this case.

  Thank you.
