New system build set up to dual boot Win 10 (1909) with Mint 19.3. Seemed to install properly however when I attempt shutdown using the Power icon and shutdown button on screen the system seems to go to suspend or something else as the Mint logo stays centered on the display and the motherboard does not shutdown, lights on and fan running. I have this loaded on an old laptop that is not UEFI with same software edition and it works great. Using sudo shutdown -P now results in logo on screen and the motherboard is still "on", Using sudo shutdown -h now results in no logo on screen however the motherboard is still "on". A physical shutdown using a long hold on the front panel button on the case is required to shutdown. I deleted and rebuilt the SSD with no change in performance. I have Mint 19.3 Cinnamon, version 4.4.8 running 5.3.0-53 Linux kernel. Rebuilt system starting with new GPT partition table initially worked fine. showing same version and kernel. Used software update to bring up to date and now has shutdown issue again. Attempted timeshift from initial install prior to updating software and failed to restart, hung with screen blank and MB on with CPU fan running. Restarted computer with external case restart and shutdown is back working. Now on kernel 5.0.0.32 not 5.3.0.53.110. Installed language and multimedia codecs with no issue, shutdown works. Installed all non kernel updates (118 items) continues to work. Need some help on this one.

Hello, Big Finn, & welcome to LQ.

Mint kernels are usually middle of the road, but reliable. It sounds like you have a kernel or ACPI problem. let me explain. First of all, Mint = Ubuntu with go-faster stripes in X, so it's an Ubuntu kernel. If there's an issue with that, it will be fixed in a few days, so sit it out. Otherwise, take the kernel as ok.

The other things affecting this are: Laptop BIOS; ACPI; Systemd; Kernel 'quirks' options.
Laptop BIOS differ, and some which don't behave have special kernel options. These can't all be configured as they conflict. I imagine very few if any are set in a distro kernel.
If you have specific types of laptops with dodgy BIOS you may need one or more of these 'quirks,' which means a kernel recompile. But as one of your kernels worked, that seems unlikely.
ACPI has events (e.g. closing the lid, suspend key, etc) linked to events. But systemd gets into that space, and thinks it's the only one there. And most Window managers get into that space, and ship their own power manager.

I don't have systemd, and (much) prefer the older Sysvinit, but Mint-19.3's setup landed jammy side up when I installed it (Last year?). I have a Samsung Laptop.

Thanks for the input. I was actually surprised when it ran perfectly on the 9 year old Dell laptop but had issues on the new desktop build. It appears to be either the new UEFI (Bios replacement) or the fact the processor is an AMD 3400G. I am hoping for a fix when they bring out the next version or update as it looks interesting.

Fitst an Apology: ACPI has events linked to scripts. I knew what I was talking about, but I don't make sure my head is out of the clouds often enough.


If I was going at anything, I'd neuter the WM power manager, and investigate what systemd is doing.

Update to the issue. Have tried again updating using the update manager this time was offered the kernel 5.4.0.37 and this worked, system restarts and shuts down properly.
