I successfully installed Ubuntu Server 12.04 32-bit on a HP Proliant Microserver, everything works perfectly but when I try to turn off the machine with the command
poweroff hangs after disabling everything and stays on the screen
System halted and can no longer interact or reach it from network, the only thing I can do is shut it down forcibly with the power button.
reboot did not work but after editing the
/etc/default/halt file, it worked:
I followed some forum where advised to modify /etc/default/grub, by changing the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
But it did not work for me.
I tried to do the opposite and disable ACPI in the BIOS and grub setting:
GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash acpi=off noacpi"
The same. I repeat there is no graphical environment.
Have someone found other solutions?
