X-Server problem, crashes? Kernel signature?

Hi all,

Today I updated my CentOS release to the latest version and afterwards installed the latest Nvidia driver (NVIDIA-Linux-x86_64-390.87.run - GTX 1080).

Code: Select all

user@machine:~$ uname -a
Linux Bushmills 3.10.0-862.11.6.el7.x86_64 #1 SMP Tue Aug 14 21:49:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

As usual, the Nouveau driver is blacklisted and I updated the Nvidia driver as many times before.
However, now the X-server startup stops and I get the console output (see pictures).

Before the X-server starts I get an error message about a missing certificate for the kernel module ...
I reinstalled the Nvidia driver and this time I tried to sign the Kernel module via the tool in the Nvidia installer, which failed ... I never had to do that...

I reinstalled the system twice ... initially the machine booted up as expected, but after some time I get the same problem ...

dmesg output:

I have no clue how to fix that ...
Please could somebody help me?

Thanks!

A binary installer from NVidia?

Why don't you use the RPM-packaged version from ELRepo?

Thanks for your response!

Well, I followed these instructions:
http://www.advancedclustering.com/act_k ... -centos-7/

I didn't know ELRepo. I installed ELRepo ... and now?
I installed kmod-nvidia, but this came from rpmfusion and not from ELRepo.

... same issue ...

[SOLVED]
The SecureBoot option in the UEFI BIOS was set to MS windows, after changing it to "other" the system booted without problems.
