I am running a GeForce 6800 GT card with the 88.61 Nvidia drivers. I run a KVM switch so I can use 2 computers. One with Vista and the other with XP. I mentioned earlier when I switch from one computer to the other, I get a device connect or disconnect alert. I have also noticed, if I do not have the Vista computer selected and it goes into a screen saver mode, if I switch back to it, there is no video signal. I have tried hitting keys to "wake it up" with no effect, hence I have to restart. If I hit the power button, Vista will go through a shutdown cycle and occasionally, the video will return when it displays the "windows is shutting down" screen. Questions: Has anyone else seen this? Is there an approved KVM switch for Vista, since I did not see one? Could it be related to the Nvidia drivers? Are there any key combinations or any other way to wake up the video signal? Thanks, Clark
