Hi All, I have a fresh gentoo install and it works fine with 4.9 kernel, nvidia video card does its job like a charm. However, I compiled a 4.15.3 kernel with the same setup, xorg-drivers recompiled, nvidia-drivers recompiled, eselect kernel set shows to the new kernel and I have strange behavior:
During boot I see a message which says nvidia.ko cannot be loaded due to some signature issue. Checking the dmesg under windows I cannot see this error message. After successful boot obviously xdm do not start, but the whole screen vibrates/blinking fast. I haven't boot from live-cd and chroot and recompile xorg-drivers and nvidia-drivers yet. I saw a few article about that this might be due to Spectre/Meltdown, but I'm not skilled in kernel things. Any suggestion what I can do? Thanks any help in advance! in dmesg I see only this: [ 3.194322] nvidia: loading out-of-tree module taints kernel. [ 3.194326] nvidia: module license 'NVIDIA' taints kernel.
