Hi, I recently did a clean install of Ubuntu 16.04 LTS on my Dell Latitude D620 laptop. When I hit the shut down or reboot option, the computer goes to the screen with the red and white dots and just stays there. I have to physically hold the power button down to get it to shut down. I previously had Ubuntu 14.04 LTS on this laptop and had no issues. Any ideas???

Thanks,

Steve

Hi Steve...

Please take a look at David Foerster's response here. What do you get when you try his suggestions? Please post the results of any code.

Hi Ardvark! I tried what he said. I had to use "sudo shutdown now". And it's doing the same thing. Goes to the ubuntu splash screen that has the red and white dots. The dots move, and that's all that happens. It doesn't shut down. I can't get to dmesg to see what it says. I know the battery's dead, so I took it out and tried it that way. It ran slower, but it's doing the same thing.

Hi...

Although originally requested for 14.04, I wonder if one of these solutions would help?

I would try a new clean install, sounds like you may have a bad copy.

Also my notebook (ASUS) doesn't shutdown properly.In difference with shsmith, ubuntu writes some log after pressing shutdown button and ends with texts:
"Powering off
hwm: exiting hardware virtualization" and that stops without powering down. I must press and hold power button then.

There is one interested message in logs written down. May be it can have some meaning:

Proces 3025 (plymouthd) has been marked to be excluded from killing. It is running from the root file system, and thus likely to block re-mounting of the root file system to read-only. Please consider moving it into an initrd file system instead.

I had to add the noapic parameter into configuration file in order booting is successful. Booting had been freezing without it.
Can it be in conjuction with the shutdown issue?
