NOT WORKING ON RPI 3B+ despite the many "fixes"

[WadDyORedDy]

It shouldn't be this hard to get a ~50 GBP monitor to work...

I have tried the solution mentioned in #177, but still not working. I do get an image though, however it's stuck in portrait mode. And the touch is working if I want to click anywhere else but where I want. So it's not a complete waste of money, as long as I don't expect it to work the way it should.. 👍

I see that other people have a similar issue with no responses (#183 and #181 ) and no solutions, so here's to hoping the money goes to some sort of development 🥇

For anyone using RPI 3B+ and just want it to work.... Just use this fix instead: https://www.youtube.com/watch?v=OJ59hXSyBoI&t=319s&ab_channel=ChrisRiley

On a 3B+ (and on earlier Pi), I needed to rotate the display in 'Display Configuration' after adding the rotation line in config.txt - after I did that touch worked as expected.

Might also be worth a try for #183 ?

I cannot make rotating my screen work either. I'm running the latest Raspberry Pi OS Lite on a raspberry pi 3B+ and tried the follow configurations in /boot/config.txt

dtoverlay=vc4-kms-dpi-hyperpixel4,rotate=90

or

dtoverlay=vc4-kms-dpi-hyperpixel4
# And one of 
dtparam=rotate=90
display_lcd_rotate=1
display_rotate=1

And nothing worked. I cannot figure out how to set 'Display Configuration' to 'Normal' in Raspberry Pi OS Lite CLI.

EDIT:

Now it suddenly works, the only thing I changed was removing a from the HDMI port, and with the following settings:

dtoverlay=vc4-kms-dpi-hyperpixel4,rotate=90

To fix the touchscreen rotation i tried asking chatgpt and it totally worked:

The HyperPixel 4 is a small TFT display that can be used with a Raspberry Pi or other single-board computers. If you need to rotate the touch input on the HyperPixel 4, you will need to use the xinput command-line utility, which is typically pre-installed on most Linux distributions.

Here are the steps to rotate the touch input on the HyperPixel 4:

Connect the HyperPixel 4 to your Raspberry Pi or other single-board computer

Open a terminal window and type the command xinput list and press enter. This command will list all of the input devices connected to your system.

Look for the input device associated with the HyperPixel 4 touch screen. It should be listed as "FT5406 memory based driver" or similar.

Once you have located the input device, use the command xinput set-prop 'FT5406 memory based driver' 'Coordinate Transformation Matrix' 0 -1 1 1 0 0 0 0 1 to rotate the touch input 90 degrees clockwise.

If you want to rotate the input 180 or 270 degrees you can use the following commands respectively:
xinput set-prop 'FT5406 memory based driver' 'Coordinate Transformation Matrix' -1 0 1 0 -1 1 0 0 1
xinput set-prop 'FT5406 memory based driver' 'Coordinate Transformation Matrix' 0 1 0 -1 0 1 0 0 1

If you ever want to go back to normal orientation you can use xinput set-prop 'FT5406 memory based driver' 'Coordinate Transformation Matrix' 1 0 0 0 1 0 0 0 1

Note that the name of the input device may vary depending on your specific setup.

In my case I had to define the device as " pointer:'Goodix Capacitive TouchScreen' " and rotate 270 degrees for the issue to get fixed.

Hope it helps someone!
