Hi Alvaro, Does this problem about the Xorg server not starting still happens with latest xserver-xorg-core and drivers? Does X crash ? Or does it just fail to display anything ? Do you get a crash backtrace and the end of Xorg.0.log (or Xorg.0.log.old) when this happens? I don't see anything like this in the log you provided, but it was not clear whether this log was the one of the X server when the problem occured. Brice
