Comment 208 for bug 987220

I installed, from pendrive, Ubuntu 16.04 LTS in dell inspiron 1501 (with windows XP), the windows poweroff normally, but ubuntu do not: it goes shutdown apparently normally but finally do not power off the labtop.

The last lines reported are: All fylesystems unmounted Deactivating swaps All swaps deactivated Detaching loop devices All loop devices detached Detachig DM devices All DM devices detached Powering off

and the labtop do not power off

Ther is a significant note in the previous lines before those lines: Process 1043 (plymouthd) has benn marked to be ecluded form killing.......

I am new and no expert linux
