GTX 970 on Ubuntu 18.04 issues

Hi guys,

Could you help me figure out how to install Nvidia Drivers for GTX 970 on Ubuntu 18.04?
After choosing the Nvidia proprietary driver (430, tested version) from “Software and Updates” and blacklisting nouveau driver, when I reboot, I get low-resolution and the running driver appears to be this one: llvmpipe (llvm 8.0 256 bits) even though prime-select query gives nvidia.

I tried also from tty with .run driver but to no success.

Please make sure you have secure boot disabled in bios.
Please run nvidia-bug-report.sh as root and attach the resulting .gz file to your post. Hovering the mouse over an existing post of yours will reveal a paperclip icon.

After disabling Secure Boot it works perfectly fine. I didnt notice it was enabled. Thank you!
