Once in a while when I install updates on my laptop and system requests a reboot, I get into a login loop. I've discovered that this is not because I have driver issues, but rather that my discrete Nvidia GPU isn't detected during reboot - in other words, lspci -nnk in a terminal session will not list the Nvidia card. If I attempt to then login to the GUI, I'm returned to the login screen. If I reboot until the output of lspci -nnk shows that the Nvidia card is available, I'm then able to login to the GUI.

In the logs, I see the message NVRM: No NVIDIA graphics adapter found! and I'm wondering if anyone else has encountered this issue and found a solution.

The laptop in question is a Dell Precision m6700 bought back in 2013 and still has a lot of life left in it. I'm running Ubuntu 16.04.2 LTS.

  • You may have to open the laptop and reseat the Nvidia card.

  • Which Nvidia driver version have you installed, and how?

  • @heynnema - I'll do as you suggest - it never crossed my mind to do that on a laptop though I've always preached that to desktop users.
