Can I interrupt a crashing/frozen Ubuntu desktop?
Is there any Linux (specifically, Ubuntu) equivalent to Window's Ctrl+Alt+Del? I am aware of the System Monitor, and of `top` on the Terminal, but the true beauty of Ctrl+Alt+Del is that it interrupts everything else, and works even when the computer is frozen and not responding to normal input. My computer does that frequently (usually because of ADHD-initiated tab explosion in Firefox, it must be said), and I am often reduced to using the physical button to restart it.

I'm currently running Ubuntu 24.04.3 LTS.
