I recently upgraded to Ubuntu 20.04. Everything worked fine. Two days ago my laptop would boot and get stuck on a black (dark purple) screen. I fixed this by changing the boot parameters, replacing "quiet splash" with "nomodeset" like my google search suggested. This worked. Now for some reason today this fix would lead to a black screen reading
"EFI stub: UEFI Secure Boot is enabled."
and nothing happening.
In BIOS I can't disable Secure Boot. (The option is there but I can't "enter" that field so to speak.)
I now disabled fast boot and which led me to the GRUB command line and I could boot. Then I restarted AGAIN and I got stuck on "EFI stub: UEFI Secure Boot is enabled." again. After enabling fast boot again, I could boot again.
machine ASUS UX303UA.202 What other information could I provide?
Any help is greatly appreciated.
