I’m trying to install Ubuntu18 on my PC.
The Ubuntu18.04 installation program cannot even login with nomodeset option. Therefore, I tried Ubuntu19.04.
I could login with “safe graphic” mode and install nvidia driver. But after the driver is installed, I cannot boot into system by nomodset.
What I had tried:
(1) Ubuntu18.04 Desktop => Install => nomodeset => black screen
(2) Ubuntu19.04 Desktop => Install => safe graphic => success to install => reboot => nomodeset on GRUB => success to boot (I can reboot to GUI with nomodeset if I do not touch any GPU driver) => Install Nvidia driver 440.64 => nvidia-smi success => reboot => nomodeset can never boot the PC.
(3) Ubuntu20.04 (daily build/ 2020.3.28) => Install => safe graphic => black screen
I’ve tried these options
acpi_osi=linux nomodeset nouveau.modeset=0 i915.modeset=0 acpi=off xforcevesa nouveau.runpm=0
