so here’s the case, your screen won’t respond, you tried waiting, but nothing happened. Ctrl + Alt + Backspace gave up on you, it won’t work. Here’s what you’d want to do to softly restart your system without breaking anything, it’s fairly dangerous to restart your machine especially when it’s still trying to do something, like writing to memory or stuff. so try this.

hold down Alt and SysRq (print screen), then type in these letters REISUB. this will turn off your services, terminate all programs, and unmount your drives, then your machine will restart.
