Comment 1 for bug 2044973

We discovered the same issue with T1000 cards in a bunch of Dell Precision 3660s. We believe the correct choice should be "nvidia-driver-535", but it recommends "nvidia-driver-535-server-open" instead, which prevents gdm and X from starting. dmesg provides the following error:
