Update some information: On Precision 7730 with NVIDIA GPU, this bug is fixed in graphic driver nvidia 430.40.
When you installed nvidia 430.40 via .run file that downloaded from NVIDIA official website, there is no any side effect. If you installed nvidia 430.44 via .deb or apt (for example: https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa), there is a side effect: If the nvidia graphic VID:PID are 10de:1bb5, 10de:1bb9 and 10de:1bbb, the gdm could not be started well. Fortunate, there is a workaround that mark or remove below line in /lib/udev/rules.d/71-nvidia.rules.
