Debian, KVM Switch, DVI-VGA adapter


Hello,

I'm a linux newbie.

I've read a ton of wikis, forums and knowledge bases trying to figure out how to get my Debian GNU/Linux 5.0.4 running KDE 3.5 to work with my KVM switch. But I can't find my exact problem. I have two problems, I think. 1) I'm using a DVI-A to DE-15 (VGA) adapter. 2) I'm using a Belkin SOHO F1DS102T KVM switch, which uses D-Sub (VGA) connectors. My video card by the way is a Nvidia Quadro FX 3400 with DVI-I connectors (interface).

I figured one of those two or the combination of the two was causing my screen to be blank when x server starts. So I ran a DVI cable directly to one of my two Dell UltraSharp 1901FP LCD monitors. It works that way. But I have two computers that I switch back and forth between, so I really could use the KVM switch. Please help me get my display to work with my KVM switch in Debian. I would also like to have dual display.

Log Time. I hope this isn't too much info. Thanks in advance.

We recently had a problem at work with a particular cheap KVM switch (can't recall the model). Our IT folks determined that some newer graphics cards go into a low power state if they don't sense an appropriate load (i.e. the KVM isn't acting enough like a monitor) and turn off the display output since it doesn't think there's a monitor attached. Maybe it's a similar problem for you. If you have a different card handy, you might try it and see if it works.
