This is the answer from the developers:
I guess for the time being I can only reinstall 4.3 and wait patiently.
And by the way, I must be cursed with Xorg and Ati issues. I tried to install 4.4 on a spare partition on the box I have windows in (I use this box the less I can since it's too noisy, not normal pc noise, REALLY noisy). Well, when I shut down X the screen first gets very dim, and if I restart X and shut it down again, I have a complete black screen, but Obsd works fine, I can type blindly "su" pwd "halt -p" and it shuts down.
Now I' in windows, and have to leave to work, should I open a new thread for this?
