Does anyone how how I can diagnose and fix this problem:
Sometimes, but not always, when shutting down the process does not actually complete and the computer does not turn off.
The screen turns off but the keyboard backlight is still responsive, the fan is still going and the power-on LED is lit. Because the screen is turned off I can’t interact graphically with the computer and have to just hold down the power button and do a hard reboot.
I haven’t tested it properly but I get the feeling it happens more often if I have been doing audio work.

How do I do that? Bearing in mind the display is off when this happens.
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 mean, give the shutdown command like this, not after already choosing it via menu. This way you may catch what’s wrong. Also, you can check the logs when you boot next time via
journalctl -b -1
but to make it easier maybe this one should be more helpfuljournalctl -b -1 | grep -i shutdown
Ah OK got you 👍
(They meant, instead of doing your normal shutdown, open a command window and type that command instead.)
