Hi, I have just installed Mint 15 as a test system before upgrading my ageing Mint 12 installation.
I am running the Cinnamon 64bit version with dual monitors on a nVidia graphics card using the default Nouveau display driver.
My problem is when using the 'Screesaver & Lock Settings'. I have it set to turn the screen off when inactive for a set time but when that time arrives both screens dim down to black, both monitors then display the 'no signal being received' message for a few seconds and then the second monitor comes back on with the dimmed wallpaper and the clock. So I am left with the main monitor going into standby but the second monitor stays on and will not go into standby.
Am I missing something somewhere or is this a bug. Is there any other way of making both monitors go into standby.
