Problem with compiz, empty desktop (SOLVED)

Hi! I installed Mate 24.04 on my latop, everything ok . Now I wish to start compiz, I installed and configured it, with mate-tweak I changed from Marco to compiz. Working fine. Excelent, I added the entry to start menu (simply the command "compiz") and rebooted. After login I see only an empty desktop, nothing at all but the wallpaper. The only tyhing I can do is CTRL+ALT+F1,2,3,4 and access to the textual login and command line. How can I reset the window manager from there?
