Ubuntu 14.04 LTS Not Shutting Down on Acer Aspire ES1 512


Hi,

I am new to the Ubuntu OS and really enjoying it but currently have an issue with my Acer Aspire ES1 512 laptop with regards to getting the machine to completely shutdown or restart.

It is not a dual boot setup, 100 Ubuntu 14.04 LTS install but when I attempt to press the "Shutdown" option at the top right, it looks like the machine is shutting down, shows the Ubuntu logo with dots but does not physically turn off the machine.

At the moment, I have to physically press and hold the power button.

FYI, I have also tried sudo shutdown -h now

Any ides/help would be great as it's the only issue I am currently experiencing.

Thanks.

Hi:

When sudo shutdown -h now doesn't work try making this change to the Grub file.

Quote:
GRUB_CMDLINE_LINUX_DEFAULT=quiet splash noapic irqpoll
Restart after you add and save that to the Grub file and see if your pc will shutdown.

Just In case it is a systemd issue. Instead of shutdown -h now. Try

Code:
sudo systemctl poweroff

Hi,

Unfortunately the suggestions provided here to power down my Acer Aspire ES1 512 completely did not work.

I have seen something about setting nomodeset within my /etc/default/grub file in 14.04 LTS for powering down machine.

Does anyone know whether this is the case?

Thanks.

Yes you can try "nomodeset" in the argument like this:

Code:
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
