[Bug 1509762] Re: services fail to start with "Failed to subscribe to NameOwnerChanged signal: Connection timed out"

 

My 15.10 "system" started to show quite similar symptoms today. Booting
with systemd the progress stops in the graphics  'ubuntu * * * * *'
displayed at the center of the screen. After maybe one minute the the
screen goes black and couple of lines are displayed proposing some
alternatives like to display journal, try again the boot.

With "upstart" booting is ok.

The behaviour has been the same for more than 10 tries.

I have not applied the patch referred above.

My laptop is dualboot Asus G751JY, with NVidia GTX 980M graphics
Linux 4.2.0-16-generic #19-Ubuntu SMP Thu Oct 8 15:35:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Windows 10

The journal is attached.

Title:
  services fail to start with "Failed to subscribe to NameOwnerChanged
  signal: Connection timed out"

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  Upstream bug: https://github.com/systemd/systemd/issues/1505

  After successful upgrading to Ubuntu 15.10 from 15.04, restart system option couldn't boot, seemed in a loop, showing mouse pointer in the center of the screen for few seconds and then a blinking cursor at the upper left corner, instead. Used Ctrl+Alt+Del to reboot and selected Upstart option which successfully booted the system but showing a message like "Upstart; Error while reading from descriptor, broken pipe."
  On my next attempt to boot using default systemd option I observed a message like "Systemd(1) Failed to setup API Bus. Connection timed out." , and then saw a window saying like "running low graphic" and then went into the same loop.
  Now, I can boot using Upstart option only not the systemd option.

  I'm using Dell Optiplex 755 with NVIDIA 8400GS Graphic card,
  Ubuntu 15.10 is installed on a external HD connected with one of external usb port.
