My LUbuntu 18.04's lxpanel is not working. Which command can I run to adjust brightness of my screen? Thanks.

First, run xrandr | grep " connected" | cut -f1 -d " " to get your screen name.
Once you got your screen name, run xrandr --output <screen_name> --brightness <brightness_value>, the brightness value is between 0 and 1.
