Re: Ubuntu won't turn off computer after shutting down
Not entirely sure this will work with grub2 but worth a try:
press alt + f2 and type
it will open a text file.
gksu gedit /etc/default/grub
look for GRUB_CMDLINE_LINUX_DEFAULT=" "
after the = sign it may say something like "quiet splash"
add "acpi=force" minus the quotes
so it should be something like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
Save and close the file.
Then open a terminal and type:
Press enter and type in your password.
Reboot, and try to shut down.
I had to do that with an older computer I had, but that was with ubuntu 7.04 and legacy grub. It may still work, though.
