Bug Description
The nvidia binary kernel driver now creates /dev/dri/card? nodes.
When switching between the nvidia and intel drivers on a hybrid system, all holders of the DRI node need to relinquished so that the nvidia driver can be unloaded so that bbswitch can turn the card off.
In order for switching hybrid graphics to not require a reboot, logind needs to close its file descriptor to the nvidia DRI node.
