Linux Mint 20 Reboots instead of Shutdown

[ChrisAJ]

Hello again and happy new year. Over Christmas I decided that Linux Mint 17 on my Acer Aspire 5 could do with updating. I duly installed Mint 20 Cinnamon and fresh installations of my favourite software etc. My problem is that it will not shutdown. Instead it reboots. I have tried "shutdown" in the terminal, changing the grub.config to acpi=force from quiet splash and back again and Alt + PrtScn + REISUO all to no avail.

I suspect it may have something to do with the bios and need to know what I have to do to make this right as holding down the power button is not really a viable option.

Many thanks, Chris

Have you tried disabling 'Wake-on-lan' in the BIOS?

[ChrisAJ]

Just checked and it's disabled.

[vimes666]

Does it also happen if you disable wifi prior to shutdown?

[ChrisAJ]

Yes it does

[Welcome]

A long time ago, I had a similar problem. My simple solution was to enter grub on the reboot, enter the command mode, and type in "halt" followed by return.

I helped someone else recently with the same problem, and in their case, the grub/halt method was the only solution that worked.

Until you find a better solution, try the grub/halt method. It's much better than using the power button.

[vimes666]

Well the next is disabling USB3 support in the bios. Not really a solution but it worked for others.

[SMG]

If you want to check the logs to get an idea of why the computer is rebooting, the following will give you the prior boot log information.

Code: Select all

journalctl -b -1 | tee >(gzip --stdout > journalctl_$USER.gz)

This command will write the prior boot log to the file journalctl_(yourname).gz and to your screen. The file will be located in your /home/login_name directory.

When looking at shutdown issues, I usually look for the line with "Playing logout sound" and then start checking the lines after that. Maybe something in the log will give an indication of what is happening so it might be easier to find a fix.

How do I get into this?

[Welcome]

The official way:
- Reboot.
- Press and hold the Shift key to show the boot menu.
- In the boot menu, press the letter 'c' to enter the command mode.
- Type 'halt' and press the Enter key.

The problem that a lot of people have is that they can't seem to get into grub. Sometimes pressing the Esc key works, sometimes pressing the space bar works, and sometimes the Shift key works. But, it's hard to get into it.

This would make it a little easier to get to the grub menu, but you'd see it each time the computer was booted. Maybe a good solution overall.

...
If you want to set grub to show automatically on every boot then run this command to open the relevant config file in a terminal based text editor with elevated privileges

Code: Select all

sudoedit /etc/default/grub

Change these lines

Code: Select all

GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0

to

Code: Select all

GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=5

Then Ctrl-X, Y, Enter to save.
Then in the terminal run

Code: Select all

sudo update-grub

Enjoy!

The problem that a lot of people have is that they can't seem to get into grub. Sometimes pressing the Esc key works, sometimes pressing the space bar works, and sometimes the Shift key works. But, it's hard to get into it.

I've read that the key to press depends on whether it is EFI or legacy boot.

-- Hold the shift key during boot to enter grub for non-EUFI/Legacy boot.
-- Hold the escape key during boot to enter grub when have EUFI boot.

However, the OP of this thread has an EFI bootable computer set to legacy boot so I do know if that changes the advice of which key to press.
