Public bug reported: I am currently running Kubuntu 18.04 Bionic Beaver with a GTX 1060 6gb. I installed the latest version of nvidia-graphics-drivers-390 and signed the modules using the following command:
sudo /usr/src/linux-headers-4.15.0-13-generic/scripts/sign-file sha256 ~/.ssl/MOK.priv ~/.ssl/MOK.der {nvidia_dkms_module}.ko This step was necessary to enable secureboot with a signed kernel on 18.04. This is required with mokutil. This process has worked without a hitch since 360 or so. Unfortunately, when I now boot, sddm refuses to load and when I run systemctl, the gpu-manager.service and sddm.service failed. I tried with the command startX and manipulating/removing xorg.conf with little success. I am now trying just to load the kernel modules using modprobe nvidia and I am getting the following error. "module: x86/modules: Skipping invalid relocation target, existing value is nonzero for type 1, loc <Random location> val ffffffffc21c04c0 modprobe: Error: could not insert 'nvidia': Exec format error." This is when installing nvidia-graphics-drivers-390=390.48-0ubuntu2. Could I perhaps have some clarity over this issue? From reading online, it seems that the kernel modules weren't built for 4.15.0-13. I have tried installing nvidia 390.48-0ubuntu1+gpu18.04.1 from the graphics- drivers ppa but that also had similar issues. ** Affects: nvidia-graphics-drivers-390 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763842 Title: Nvidia invalid relocation target when performing 'modprobe nvidia' on 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1763842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
