I am having this issue too. I have a Dell Vostro 5470 notebook, i5-4210U processor, 8GiB DDR3 RAM, 480GB SSD and a GeForce GT 740M. I have a dual boot instalation alongside Windows 10. After installing Ubuntu 20.04, after the POST screen, all that is shown is a blank screen with a cursor (not blinking) and, after a while, Ubuntu is loaded. Using the arrow keys I am able to select another option, but I can't see them.
I tried installing grub-customizer and changing some options (like grub resolution and font style and size), but it didn't work. Below it the grub version that is installed: Package: grub2 Version: 2.04-1ubuntu26 Priority: extra Section: universe/admin Origin: Ubuntu Maintainer: Ubuntu Developers <ubuntu-devel-disc...@lists.ubuntu.com> Original-Maintainer: GRUB Maintainers <pkg-grub-de...@alioth-lists.debian.net> -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863434 Title: 20.04 grub menu not visible To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1863434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
