I have ubuntu 20.04 on my laptop. Recently when I turned my laptop on, it suddenly got stuck with a blackscreen. Figuring it was a graphic driver issue, i enter in with nomodeset, and tried to purge and reinstall Nvidia-driver. Now I cannot install it, nvidia-smi is giving me failed. I cannot sudo modprobe, since I have secure boot on. But if I disable secure boot, my computer get stuck in blackscreen again. Anyone has this issue before? Please help
Basically the only way i escape the black screen is booting with Secure Boot and nomodeset.
