I have a weird question here but I need an answer as fast as possible :(

For a specific project I have to start a QT-Program on the screen on startup in Linux Mint 9. The Monitor which is displaying the program turns off after an unkown amount of time. I already deactivated the turnoff in the systemconfiguration but it doesn't seem to work.

Hardwarespecs: CPU: Intel ATOM 330 GPU: Nvidia ION (330) 2GB RAM OS: Linux Mint 9

I can't change the OS and the other specs... Do you guys know what I can do to solve this problem?

Open the Power Manager. Select the Display tab. On the left where is says "Blank after", move the slider all the way to the left under Plugged In, or the corresponding power type, batter or plugged in. This is assuming it's not the screen saver that is making your monitor go blank.

This is for Linux Mint 17.2, so I'm not sure if it will be the exact same with your older version.
