Public bug reported:
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.
