Raspberry PI 4 Model-B with Ubuntu 20.10 Desktop Will not Post After Applying Drivers #14

HI LCD Wiki Team,

I applied the following on a working build Ubuntu 20.10 desktop installation:

git clone https://github.com/lcdwiki/LCD-show-ubuntu.git chmod -R 755 LCD-show-ubuntu cd LCD-show-ubuntu/

In case of 3.5" HDMI Display-B(MPI3508) sudo ./MPI3508-show

After reboot, the screen shows the multi-colored rainbow gradient that occurs during Raspberry Pi's post sequence, but the gradient does not go away and the machine cannot be connected to from the network and even USB keyboard does not work. Effectively the driver has bricked the machine and I will have to reimage to a backup.

Is this the wrong driver for this application? Or if not, can you see if you can reproduce this issue on your end?

Having the same exact issue on my Rpi 4 with different screen using LCD35-show script. It just shows rainbow screen and never goes away.

Same here with the MHS40 screen. How'd you fix it @Haxk20?

Thanks, it works fine now although there is terrible screen tearing and some windows will not resize to full screen when maximized. Any idea of why that might happen? I think it's just an issue with the screen that can't be solved but I'm a newbie so I got no idea.

it's not working on my case. I already add on my config but my RPI still stuck on boot is there a way to revert it back without re install the os?
