Missing screensaver in control panel

I am unable to stop screen blanking because ther e is no 'screensaver' in the control panel
Even just upgrading Jammy to 5.15.0-138 no effect.

any adjustments in dconf edsitor ?

It is quite surprising!

  1. Please double check
  • System > Control Center menu entry and since then Look and feel section.
  • System > Preferences > Look and feel > Screensaver menu entry.
  1. Not only screensaver can clear the screen. I'd suggest to verify
  • BIOS power saving options.
  • Mate power management preferences.
