I've installed ubuntu 14.04 on my old notebook (Acer Travelmate 2420).

Everything is fine except the shutdown.

It's hanging in the last screen ("ubuntu" with the points beneath - they change their colour properly. As long as I don't press the "on/off" button of the notebook).

I've changed this line:


into this:

 GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

it doesn't work.

Can anybody help?

I'm a ubuntu beginner, so I maybe don't understand too specific things.

did you run update-grub after you change that line? – JoKeR Jun 10 '14 at 1:03
yes, i did. thanks. – hns Jun 10 '14 at 7:56
so you did it before I told you that? what is kernel version in your system uname -r ? – JoKeR Jun 10 '14 at 9:33
yes, i've done the things step by step as written down somewhere in the net. here is what comes, if i type "uname -r": 3.13.0-29-generic – hns Jun 10 '14 at 12:20
take a look at this… there's a lot of issues can be that you can find within forum – JoKeR Jun 10 '14 at 12:27

While you see that purple screen, you can press ESC to see exactly what Ubuntu is doing, which may be very useful if this turns out to be a bug, or if you just want to see what is taking so long.

Try going into Terminal and typing sudo shutdown -P now that ought to force Ubuntu to completely shutdown, if not then we may have to dig deeper.

the last 2 lines are: * Unmounting local filesystems [OK] * Will now halt – hns Jun 10 '14 at 12:28
it's still the same with: sudo shutdown -P now – hns Jun 10 '14 at 12:36
Sounds like an uncommon but not unheard of bug. I refer you here:… In the hopes your grub is configured similarly. With any luck you may have just been missing two lines of grub args. – agentroadkill Jun 10 '14 at 20:45
after several grub-changes i decided to install a new operating system. tried lubuntu: same problem. tried ubuntu studio: everything works as far as i can see including the shutdown. so all seems to be good in the end. – hns Jun 11 '14 at 11:57
