When I press the gui shutdown button, the system is not powering off, but rather just remains at splash screen. Hence, I always have to power off the machine manually holding the power button. Issuing shutdown -h
or shutdown -P
from command line works fine while shutdown -H
causes the same problem as the gui shutdown.
I use ubuntu 13.10 (uefi version) on an Acer Aspire V5-573G. Adding the line "INIT_HALT = POWEROFF" to /etc/default/halt as suggested here does not help.
Any suggestions are very welcome!
