I accidentally paused the Linux display process

After installing Linux Mint 19 I wanted to check how vsinc affects fps in Linux, so I typed this command: CLUTTER_SHOW_FPS=1 cinnamon --replace

After some time I accidentally pressed Ctrl+Z and paused that process. Immediately my Bash shell and everything except the mouse cursor froze, so I can't type the fg command.

Is there a way to unpause that process without rebooting and should I use Ctrl+C next time to properly exit that process?

Next time, run it with CLUTTER_SHOW_FPS=1 cinnamon --replace & to start it in the background. Replacing it again with a process with a process started without CLUTTER_SHOW_FPS should do what you want. Or yeah you can control-C it; X11 works with no window manager; your terminal emulator should still be visible for you to start another window manager.

i suggest always having SSH access to a machine you don't want to hard reset, but this should not be your primary fix for this issue

Switch to a new TTY. See How to switch between tty and xorg session? for tips on how to switch TTYs.

Determine the PID of the cinnamon process
ps -e | grep cinnamon

Send this process the SIGCONT signal with kill -SIGCONT [pid]

+1. Clarification on the statement "kill [...] process with the signal" would be good. The naming of the kill utility is unfortunate, given that most of the signals one can send are not used to 'kill' a process in the sense of mortality. kill -SIGCONT 9999 will send the continue signal to the pid 9999.

@Tomislav can you clarify what you mean by distorted? It sounds a bit like your tty7 just has a regular (GUI-less) shell rendering.

It looks like normal desktop after booting but without start menu panel (icons on desktop are also visible).

Short, concrete version of CameronNemo's answer:

ctrlaltF1 ^{_{# Switch to TTY1}}
user nameÃ¢Â†Â² _{_{# Log in on this terminal}}
passwordÃ¢Â†Â²
killall -SIGCONT cinnamonÃ¢Â†Â² ^{_{# Send the continue signal to the process}}
ctrld ^{_{# Log out on TTY1}}
ctrlaltF7 ^{_{# Switch back to the graphical environment}}

F1 and F7 here assume that you have X running on TTY7, as is standard on Ubuntu and, I assume, also on Mint.
