Yes, I figured that the KVM does not emulate the VGA connection properly.  I wonder if it is possible to force the full X startup without the monitor detection.  I've tried to reset with full KVM focus but still plain X.  I did try reboot with the monitor connected directly and mouse keyboard through KVM, the full X works in that case.  So maybe the detection can be bypassed, or even if no monitor detected, the full 4Dwm is still loaded.

Edit:  Looked into this a bit more.  Like you said, the Ip KVM does not emulate EDID info.  Need to use an EDID emulator pass-through device to make the monitor detection proper.  Ebay has plenty of this stuff usually used, for fairly cheap.
