Hello,
Same problem with Raspberry Pi4 and Ubuntu 64 bits.
After running LCD5-show script as sudo, Pi rebooted but only indicator that Pi is on after that is that screen's backlight is on.
It will not boot or let me log on other screen.

I need Ubuntu 64, not Debian, because of packages available for that distribution.

Thanks for investigating why it bricks at boot

It looks like the 20.10 64 bit default config is missing from the repo, so what it replaces config.txt with isn't enough to boot.

If you are running 64 bit version, you need to copy config file from 20.04-64 bit, otherwise the config.txt file will miss essential information to boot. Please check this #10
