Switching to a TTY screen and doing the sudo poweroff command. In my testing, I also found that opening a terminal in the regular desktop environment also worked.

I was also experiencing your same issue, just tried @muhyb@programming.dev’s recommendation, and my computer shut off completely as desired.

Edit: I also opened a terminal and “sudo poweroff” and “sudo shutdown now” both work, so for me, I didn’t need to switch to a TTY console.

I also have had this issue recently. The OS will be off, but the hardware itself (fan, lights, etc.) is still running

If you haven’t noticed yet, the Linux community gets pretty divisive about distros. For what it’s worth, my friend swears by Ubuntu. Personally, I use Linux Mint, which is based on Ubuntu, and my issues are pretty infrequent or troublesome.

Linux Mint Cinnamon was my first stepping stone off of Win10. It’s been wonderful.
