I've been getting a message on my monitor where "Input not supported" is floating around. This only happens when I manually turn the monitor off and then later turn it back on. Leaving the monitor on and allowing it to go to the screen saver doesn't seem to cause the issue (but I prefer to turn the monitor off if I'm going to be away from the computer for any length of time).

Any ideas what might cause this, only when the monitor is turned off manually?

Specs:

• Acer X203w mointor
• Radeon 9600 Pro Video card
• Linux Mint 8
• Resolution 1680 x 1050 (16:10 - Preferred native resolution for the monitor)
• Refresh Rate 60hz

Here is what is in my xorg.conf file:
