Comment 22 for bug 1126234

After upgrading to saucy, the problem is back.
ubuntu-drivers debug shows the following issue:

=== log messages from detection ===
DEBUG:root:X.org log reports loaded intel driver, disabling driver nvidia-173 for hybrid system
DEBUG:root:X.org log reports loaded intel driver, disabling driver nvidia-304 for hybrid system
DEBUG:root:X.org log reports loaded intel driver, disabling driver nvidia-304-updates for hybrid system
DEBUG:root:X.org log reports loaded intel driver, disabling driver nvidia-319 for hybrid system
DEBUG:root:X.org log reports loaded intel driver, disabling driver nvidia-319-updates for hybrid system

Although my monitors are connected to the nvidia card, not the intel , and X runs via nouveau.
