Hi,

The freeze does not happen anymore, so I think this was fixed in a way or
another, thanks :)

I noticed some strange behaviours that I detail after for the record:
1) turning off the monitor (or unplugging it from power) doesn't seem to be
noticed by xorg!
2) unplugging the mini-dp plug get detected of course
3) unplugging the dvi cable from the mini-dpo adaptor gets these erros in
