>>Tried switching ports on KVM? I didn't think of that, so on your suggestion, I did try it, but still didn't get any love from the mouse >>when booting, let the boot process finish before you switch >>ports. Other than that, my two belkin 6 porters work like a champ! >>Hope that helps.... You know... I can't explain it, but it works. I was really hoping to be able to offer back a set of clearly defined steps to follow in order to resolve this question (I really like it when I see them, so I try to do that whole 'golden rule thing). I let the computer boot completely, leaving the kvm set on my linux box for the entire cycle. Upon logging in and entering 'startx' I thought for a moment that it didn't work, and the mouse was still sitting there, unresponsive in the center of the screen. However, after a few seconds, I noticed that it moved. I had occasion to add a new UPS to the server last night, and when I restarted, I did NOT set the KVM to view the CentOS screen. Instead, I was busy with some work on my Windows desktop. When I switched over to take a look, I noticed that after starting up the X server, my mouse worked just fine. It figures! Unfortunately, it kind of "just works" now, I don't know whether it's in the completion of the boot cycle before switching over, or whether there are other factors involved. >>They had a firmware patch for the kvm on the site, >>but it wasn't exactly a painless progress to update the firmware. Thanks, I didn't know that, I hope that I don't need it. Ron Jones Alpharetta, GA
