I'm having trouble with my Linux system because it has frozen up unexpectedly. I'm looking for the equivalent of the Ctrl+Alt+Delete shortcut to restart or manage processes. I've seen some advice on this in the past, but a lot of it seems outdated and hasn't helped me. Any suggestions on what I can do?

When you say it's frozen, what do you mean exactly? Can you still open a terminal with Ctrl+Alt+T? If so, you can type `sudo reboot` there to restart the system without needing to force it.
Have you tried switching to another tty? Just hit Ctrl+Alt+F2 or F3, etc. If you can log in there, you can check running processes and perhaps kill what’s causing the issue.
If it's just a specific window or process that's stuck, you can try using `kill` or `xkill`. For a complete freeze, you might have to resort to the 'magic SysRq key' technique. Just make sure it's enabled in your settings. If you can access a terminal, using the key combo Alt+SysRq followed by 'reisub' can help reboot your system safely.
Unfortunately, nothing responds at all right now. I'm really stuck!
