Hi List,

I have a Sun Blade 2000 WorkStation with Solaris 10 06/06 installed.
I also have a Belkin 2-port USB KVM switch, which I use to connect to the
Sun Blade and a WinXP PC.

It all worked perfectly fine, until I installed on the Sun WS the latest
Solaris 10 Recommended Patch cluster.

After that, when I switch from the WinXP PC to the Sun WS, I see the
Solaris GUI login screen for a few seconds (can't even finish typing my
user name) and then get switched back to the Windows box.
(remote GUI access via the likes of X/Cygwin and Exceed works fine, as
well as CLI ssh connectivity).

I've since updated OBP and POST to the latest for the Sun Blade 2000
(patch 118323-01) but to no avail.

All I see is the following in /var/adm/messages:

Any idea about how could I fix this?

Thanks in advance
