wheezy

in VirtualBox

XFCE installs and boots correctly.

The mouse cursor not working?

Can still open the Run dialog with Alt+F2 to start a terminal however.

DNS+networking seems okay.

Can apt-get update but the security suite wasn't enabled by default - it's commented out in /etc/apt/sources.list - that's OK since kfreebsd wheezy didn't any repository for security updates.
