Shutdown not completing cleanly on Ubuntu 22.04

jp flag

I recently did a clean install of Ubuntu 22.04 on my 2008 MacBook 4.1 and then installed the Unity desktop. (I actually like Unity and am prepared to take the performance hit compared to a lighter desktop.)

OS: Ubuntu 22.04.2 LTS x86_64 
Host: MacBook4,1 1.0 
Kernel: 5.19.0-41-generic 
Uptime: 18 mins 
Packages: 2138 (dpkg), 10 (flatpak), 
Shell: bash 5.1.16 
Resolution: 1280x800 
DE: Unity 7.6.0 
WM: Compiz 
WM Theme: Yaru-dark 
Theme: Yaru-dark [GTK2/3] 
Icons: ubuntu-mono-dark [GTK2/3] 
Terminal: gnome-terminal 
CPU: Intel Core 2 Duo T8300 (2) @ 2.4 GHz 
GPU: Intel Mobile GM965/GL960 
Memory: 1579MiB / 3903MiB 

Everything works great except that when I shut it down, the shutdown doesn't complete. This issue also happens with Gnome 3.

If I choose verbose shutdown so I can see what is going on, the process completes without error and the screen goes black but the fans remain running and the white light on the front illuminates if I close the lid. I have to then hard shutdown by holding the power button down for 5s.

Does anyone have any tips to force a complete shutdown on this hardware? Just in case its relevant, reboot works fine.

Please refer https://askubuntu.com/help/on-topic, Ubuntu and official *flavors* of Ubuntu (https://ubuntu.com/download/flavours) are on-topic on this site. The on-topic link provides alternate SE sites for non-Ubuntu OSes. Ubuntu Unity 22.04 was a *respin*, as it wasn't an official flavor until Ubuntu 22.10. You'd be on-topic here with 22.10 & 23.04, but you're not with 22.04 or earlier (nor Linux Mint)

I solved it by adding acpi=force to the grub configuration.

  1. sudo nano /etc/default/grub
  2. Add acpi=force to the GRUB_CMDLINE_LINUX_DEFAULT line e.g. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
  3. sudo update-grub

And now it shuts down cleanly!

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
