Black screen on Ubuntu Server 20.04

[skylarweaver]

I've spent days, many hours trying many fixes (both proposed here and on goodtft github), no avail. Please help.

I boot a fresh install of Ubuntu Server for Raspberry Pi 20.04 64bit. I clone and run this scrip as advertised while ssh'd in, and it seems to complete without issue or error. The screen is white initially, but after the script, the device reboots and the screen turns black.

I have not been able to get the screen to not be black. Not command line, no terminal, no cli. Just black. Please help @lcdwiki @goodtft.

Thanks

@skylarweavercomente esta linha dtoverlay=tft35a:rotate=90e adicione esta linha

dtoverlay=piscreen,speed=16000000,rotate=90

Essa linha está em qual arquivo?

adicione-o /boot/config.txtou/boot/config/config.txt

In my /boot/config.txt file I just have this:

hdmi_force_hotplug=1

hdmi_group=2

hdmi_mode=16

[mrfoxie]

just add this line at the bottom of /boot/config.txt this will solve the issue

dtoverlay=piscreen,speed=16000000,rotate=90

I already did. Twice. It seems everything is ok, it restarts. The screen goes white, then black and that's it.
