Lubuntu 14.04 won't shut down

[chris-burmajster]

Hello everybody,

I just did a clean install of Lubuntu 14.04 on an old Acer Travelmate 2410 laptop to replace Windows XP. Everything is fine except that it won't shut down, it just hangs on the shutdown screen. Only a hard shutdown will actually shut the machine down. Specs are Intel Celeron 1.60Ghz, 1.5Gb of RAM and a 100Gb hard drive. Please can somebody point me in the right direction?

Many thanks,

Chris

Have you tried using the terminal?
Ctrl+Alt+t will get a terminal. Then enter

sudo halt

or

sudo shutdown -h now

You will of course be asked for your password. Enter it.

For your information you can also reboot using the terminal to reboot

sudo reboot

Alternatively,
1. Hold down the Alt and SysRq (Print Screen) keys.
2. While holding those down, type the following in order. Nothing will appear to happen until the last letter is pressed: REISUB
3. Watch your computer reboot magically
This works on most computers.

Hi Rex,

Thanks for responding! I tried all your suggestions and the only one that works is the REISUB. Only that and holding the power button down will make the computer switch off or reboot. It's almost as if something is missing, or didn't install correctly in the first place. Do you have any other suggestions as to how I can correct this problem? The machine will be going to somebody completely non technical, so it all needs to work.

Thanks,

Chris

Hi bapoumba,

Thanks for your response. I looked at the link and I have already tried editing the grub file to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force" as suggested, but I was not able to save the changes, as it said that I didn't have permission to do so. As it was a fresh install I have decided to put Lubuntu 13.10 on in it's place, as I never had any problems with that on another computer. I searched the internet and saw that many who updated from 13.10 to 14.04 didn't have any issues (including myself - both my main computers upgraded to (Ubuntu) 14.04 without any problems), so I'm now putting 13.10 back on and after checking that it all works correctly, will upgrade to 14.04 internally. It's a bit more work, but I'm hoping that it'll cure the problem.

OK thanks, please report back if you see it fixed the shut down problem. That may help others.

Update: I wiped 14.04 and did a fresh install of 13.10 using the same disc that I used successfully on my other machine. It shut down and re-booted without problem. I then allowed it to upgrade itself to 14.04 and tested the shut down and reboot. It failed to shut down or reboot. I can only assume that this is a bug and I hope that Canonical will fix it, as 14.04 is currently unusable.

I have no idea if this would work : https://help.ubuntu.com/community/Gr...utdown_freezes

Which video card do you have ?

Hi bapoumba,

As I mentioned in a previous post, I have already tried this. It wouldn't let me save the alteration, it said that I don't have permissions. How do you open that file as root?

Thanks,

Chris

Did you use

sudo nano /etc/default/grub

nano is a small terminal editor. Will ask for your password, ctrl-o (letter o) to write changes and ctrl-x to save.
Please make a backup before editing the file

sudo cp /etc/default/grub /etc/default/grub_bak
