I finally managed to downgrade to the old Xorg after considerable difficulty. What hardware do you have? Are you sure that the system froze, and not only that the console went black? Did you check any logs (dmesg, xorg log, etc.) How do you load the kernel modules for the intel kms driver? In general, you shouldn't need to load anything at all, X loads the correct kernel module at the correct time during startup. > > I'd like to try again on a new computer, with FreeBSD-current/HEAD (10.0 is in the not-so-distant future?). 10.0 is slated to arrive in a few months.

Check the guide. In general you plug the firewire cable from one computer into another computer, and use the first one to debug the second. > >>> Would it work to have two xorg.conf files, one with Intel driver and the other with vesa?

No, using vesa driver won't load the KMS module, but once you've loaded the KMS module, you can't get the console back short of a reboot. > > What about "xorg -configure" which I might want to do the first time? In general you don't need very much in terms of a config file any more... It was some time since I set up my own X, so I can't remember how xorg -configure works, you have to try yourself.
