My laptop, Lenovo Z40, has NVIDIA GeForce GT820M. With nvidia-340 driver installed it won't boot to SDDM (also tried with LightDM). Opening up another TTY is useless because the same message "PKCS#7 signature not signed with a trusted key" keeps getting spammed. I had to go to recovery to switch to Intel graphics.
