FreeBSD 8.1. Xorg собран из портов. Черный экран смерти (как с -retro, так и без оного).
Более того, при старте X компьютер перестает пинговаться! То есть виснет вообще наглухо.
Для чистоты эксперимента была проинсталлирована чистая FreeBSD и Xorg собран только с конфигурацией по-умолчанию - ничего не трогал.

Xorg detected your mouse at device /dev/sysmouse.
Please check your config if the mouse is still not
operational, as by default Xorg tries to autodetect
the protocol.

Xorg has configured a multihead system, please check your config.

Your xorg.conf file is /root/xorg.conf.new

To test the server, run 'X -config /root/xorg.conf.new'
