Belkin Flip KVM Switch and Blue Screen

Question

Belkin Flip KVM Switch and Blue Screen

G5 Dual 2ghz, clean install of Leopard.

I have a dual head video card, attached to the DVI port is a 22" monitor connected via DVI, on the ADC port I have ADC to VGA adaptor which a Belkin "Flip" KVM switch is attached, leading to a 17" monitor.

On booting I get to the point when the Finder should be loading and get a blue screen on both monitors, the monitors both periodically do a fade from black as though the system has just tried to change video resolution. However this loop continues.

If I remove the KVM and have the 17" plugged in, boot up is fine. This set up worked fine with 10.4x.

Any suggestions.

Thanks

PowerMac G5 Dual 2Ghz, Mac OS X (10.5.6), Belkin KVM

Is the Flip KVM mac OS X 10.5.6 compatible??
According to the Belkin website it was made in 2007, so it may need an update...

Zork, have you cracked this problem yet?

I have a similar item - Belkin's Switch2 for Mac mini - and I get the same halting at the blue screen. Belkin UK's 2nd line support failed to replicate this error and replaced my device with the one that they used. It failed as well on my system (which works fine without the Switch2!).

In case it helps, a dig in the logs showed the following fault repeating itself presumably while the screen stayed blue:
(starts 6 lines down, I think)

...and repeats it every 9-10 seconds.

Do/did you get this as well?

Can anybody comment on what is going on, please?
