UI Switch GPU Mode does not change mode

Created by: alu18999959g

I currently have "nvidia" mode enabled with :

sudo envycontrol -s nvidia --force-comp --coolbits 24 from terminal.

...But i choose from the applet (Optimus GPU Switcher") "discret" or "hibrid" nothing happens...i try reboot but doesn't works, always is display nvidia on the applet.

Debian 13 Testing my system.

Thanks!
