I've been dealing with this problem on and off for about a month, and I've been spending quite some time on the side trying to fix it. I think it's now time to ask for help.

So, when I boot my laptop, one of 3 things can happen.

  1. The computer boots fine, no problem.

  2. The computer boots and I get a message saying that the computer is running in low graphics mode. If I select the option to try running the default mode, then it runs fine.

  3. The computer doesn't boot at all. The booting process stops at Loading initial ramdisk....

From what I've researched, it seems like Nvidia drivers might be causing this problem. I am currently running driver 390.12, but I've tried pretty much all the ones in the graphics-drivers ppa, and the problem persisted.

It is possible for me to force the laptop to boot by adding the line acpi=off in the GRUB menu. This, however, forces the laptop to run with the integrated Intel graphics card, which is not ideal.

Here are my specs:

  • Computer: Lenovo Thinkpad P50
  • Graphics card: Nvidia Quadro M1000M (GM107GLM)
  • OS: Ubuntu 16.04

I don't think it matters that much, but I'm also dual booting with windows 10.

Any help would be greatly appreciated and let me know if I should add any other information. Thanks!


If this is helpful to anyone having similar problems, the issue was solved by updating the BIOS with the latest found on Lenovo's website. Lenovo seemed to only offer those for Windows, so I needed to update on the Windows side. Everything is back to normal now!
