LCD 35 Screen not working with Pironman 5 Max and Ubuntu 22.04

Accessories for Raspberry Pi and Arduino
1

I tried using the instructions on this page to get the LCD Screen:

And I downloaded for ubuntu per your instructions.. the LCD screen starts showing the ubuntu logo and spinner.. but after a few seconds just freezes.. I can still ssh into the computer and when I do I found this in the syslog continuously repeating.. I’m using Ubuntu 22.04.

We recommend providing a video of the issue so that we can better assist you in analyzing and resolving the problem.
Are you using the correct installation commands for your corresponding system?
If you are using Ubuntu, please follow the instructions below to install:

I did the following.. first I removed the RGB jumper pin you mentioned..

On the IO Expansion Board, remove the jumper cap connected to the RGB pins to disconnect the RGB LED from the SPI interface.

Then I ran the following commands..

pironman5 -re false
sudo systemctl restart pironman5.service

Next I ran the commands above:

sudo rm -rf LCD-show-ubuntu
git clone https://github.com/sunfounder/LCD-show-ubuntu.git
chmod -R 755 LCD-show-ubuntu
cd LCD-show-ubuntu
sudo ./LCD35-show

after a restart the following is what I see.. speed forward to the 55 second mark

as I cannot upload attachements I put the video on youtube as unlisted..

One other thing of note.. when I go to shut down next will show up on the screen.. so apparently the X Server is not correctly starting up..

We have fixed the issue.

We recommend that you remove the driver and then reinstall it to see if the display works properly.

sudo rm -rf LCD-show-ubuntu

I got impatient and started researching solutions and solved my problem ahead of your sharing this here… I found most of what I needed via ChatGPT and send privately send a link to what I used… based on what I read my solution overlaps how you resolved it.. at least some.. my challenge was that I’m using Wayland and your driver fork was relying on X..

Now I need to get the touchscreen working (it responds but is grossly out of calibration) and the Raspberry Pi camera module (it isn’t even seen by Ubuntu - I’ll start a separate thread on that). Also I had to change the dtoverlay specifically for the difference in pins that needed to be used (the piscreen overlay wanted to use pin 17 so I recompiled it to use pin 18) so that the touchscreen ads7846 overlay would use 17 and there were no conflicts.. the following was the final result for /boot/firmware/config.txt
