I solved the problem!
The file 40-Keyboard.conf error. Rule change the layout of groups somehow written in the line:
Option "XkbVariant" "grp:alt_shift_toggle"
Should be as follows:
Option "XkbOptions" "grp:alt_shift_toggle"
Forwards, save, restart X-server. Does not work! Why?
It appears in the directory /etc/X11/xorg.conf.d/ there is another file with the description "XkbOptions". This file 40-evdev.conf with line:
Option "XkbOptions" "terminate:ctrl_alt_bksp"
Since the file 40-evdev.conf read before the file 40-Keyboard.conf, then the values of "XkbOptions" from the second file will not be accepted!
Log out. Remove the line:
Option "XkbOptions" "terminate:ctrl_alt_bksp"
from the file 40-evdev.conf, and a value of "terminate: ctrl_alt_bksp" moved to file 40-Keyboard.conf. Should be:
Option "XkbOptions" "grp:alt_shift_toggle,terminate:ctrl_alt_bksp"
Developers! Please correct it!
