Touch screen is backwards
Installed on Raspbian Stretch and display works but touch screen is backwards and flipped. If I touch and move up and down the cursor moves left and right, if I move left and right it moves up and down.
And the cursor location when touching the screen is opposite where you touch. If I touch screen in upper left corner the cursor jumps to bottom left hand corner.
I did come up with a solution to this issue but I would have to look at my Pi to see what I did exactly if you are still having the issue let me know and we can compare our configs. When I get time I will post my solution here anyway in case someone else has the same problem.
OK I finally found the solution. Since Rasperian “Jessi” version the kernel / img uses libinput as it's mouse drivers instead of the old evdev, which ignores 99-calibration.conf swapaxis options. The LCD touchscreen drivers as provided on this git still relies on evdev. See here how to resolve it: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=179477#p1163460
@goodtft can you please fix this in the code. Thanks!
On a raspberry pi make sure the hostname is exactly raspberrypi. Eg your prompt is pi@raspberrypi If not, correct it in raspi-config under network options.
After this, run sudo ./LCDxx-show again
At least this worked for me with a raspberry pi 3b and a Velleman VMP400 screen.
Hi all, please help to check if this problem still happened in the latest driver on github. Thanks!

lcd_rotate=2 is the solution. sudo nano /boot/config.txt Add one of the following lines to the bottom of the file :
display_rotate=0 display_rotate=1 display_rotate=2 display_rotate=3 0 is the normal configuration. 1 is 90 degrees. 2 is 180 degress. 3 is 270 degrees. If you are using the Official Raspberry Pi touch screen you can use “lcd_rotate” rather than “display_rotate”. Save the file by using CTRL-X, Y then ENTER. http://osoyoo.com/2016/05/26/osoyoo-lcd-touch-screen-for-raspberry-pi-installation-guide/
and lastly you will need this part http://www.circuitbasics.com/raspberry-pi-touchscreen-calibration-screen-rotation/ its all reading and maybe a 10 min vid to watch you will have it done in 30 min :)

I just got my mpi3508 display and downloaded the driver today, and I'm getting this issue

which OS are you using(UBUNTU,KALI,RASBIAN....)? we can not reproduce this issue.

To solve the Problem:
sudo apt-get install xserver-xorg-input-evdev
sudo cp -rf /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf

Confirmed this is the solution. I just installed Stretch and the latest drivers from this repo and all is good. I did have to make sure to include dependencies however, so add the "-f" if you need it.
All I had to do to fix this for me was edit the file /etc/X11/xorg.conf.d/99-calibration.conf and change the line that said invert axis to 0 (false/off)
As of 6 November 2021, I can confirm @Ricardo-Osorio 's comment. All I required was playing with "SwapAxes" and "rotate.sh" command in this repo
