** Description changed: Installed 20.04.2 LTS,changed the updater settings and upgraded to 20.10 After boot GRUB is presented as normal When selecting the default Ubuntu (or waiting the timeout) then blank screen occurs Backlight is on but the boot does not proceed I have tried editing the command line with combinations of acpi=off and/or nomodeset without effect. Also, even if I remove spash & quiet there is still no output at all. This bug was filed from a clean, updated 20.04 LTS because once I did the upgrade there was no system available to report the bug from. Here is something else: I tried the 20.10 and 21.04 desktop installers (from USB stick) and the behaviour is exactly the same - get to GRUB, - select either Ubuntu or Ubuntu (safe graphics) and then just the back + select either Ubuntu or Ubuntu (safe graphics) and then just the black screen. I tried the 20.10 server and that could proceed to the text-based installation. Obviously the desired outcome in either the upgrade or installer scenario is that the system boots in a usable manner!
