What worked for me was setxkbmap -option grp:switch,grp:alt_shift_toggle,grp_led:scroll us,ru
You need to create a file /etc/X11/xorg.conf.d/00-keyboard.conf for this you can use this command:

localectl --no-convert set-x11-keymap us,ru grp:switch,grp:alt_shift_toggle,grp_led:scroll

If you wanted to enable the Ctrl+Alt+Backspace sequence to kill the X server by default

setxkbmap -option "terminate:ctrl_alt_bksp"

localectl --no-convert set-x11-keymap us,ru grp:switch,grp:alt_shift_toggle,grp_led:scroll,terminate:ctrl_alt_bksp
