I had expected dmesg to say something when I plugged the DisplayPort monitor in, or I had at least expected something in dmesg mentioning that it knew there was a DisplayPort device on the system (`dmesg | grep vga | wc -l' gives six results, for example). I had assumed, because of all this, that FreeBSD simply didn't recognize DisplayPort. This laptop has two graphics cards in it; I'm currently using the Intel GM45 which you mention probably doesn't support DisplayPort. The other card (ATI Mobility Radeon 3650 HD) causes the system to hang just after the boot prompt (where it displays the |/-\ animation, but it hangs on the |). So that's where I am now. Moving forward: who do I pester about getting the Intel card to understand DisplayPort? Where do I file a bug about the ATI card preventing the system from booting (and how do I even send useful information besides "it doesn't boot")?. Also, Robert, thank you for responding.
