I have KVM set up on a QM57 with a i7-620M and the video works fine but the keyboard and mouse both do not work. I tried using both the RealVNC Free Edition 4.1.3 viewer and the version in the SDK.
When I look at the remote control section of the web interface it says "This computer does not support Remote Control Operations." Does this have something to do with it? I know it's refering to the ability to remotely turn the computer on and off but I hadn't seen that before.
