imposible rotate screen
Everything I have found on the internet, refers to the Rasberry Pi3 or 4 and not to the CB1, I do not see how to rotate the screen. Supposedly there is an option in system.cfg to do it but nothing. I listen to suggestions; I've been looking all over the internet for several days and nothing.
correction, the system.cfg does work; but not that, it rotates the touch so, not the image
I'm having this same issue with the TFT35 SPI and CB1. I was able to change the transformation matrix without a problem (ie the "touch" screen registers the correct orientation but the display is not correct).
I got it to rotate by running
sudo nano /etc/X11/Xwrapper.config
and adding lcd_rotate=2 or extraargs=fbcon=rotate:2
HOWEVER, restarting KlipperScreen then asks for a login and only shows console.
I suspect the software that runs the rotation requires root, which I'm not sure how to do at this point. The strange thing is however... if I run 'systemctl status KlipperScreen', one of the lines I receive states '***** KlipperScreen-start.sh[8652]: extraargs: Invalid key '/usr/lib/xorg/Xorg.wrap' at /etc/X11/Xwrapper.config line 16'. Not sure what this means, but may be why it's requiring a login.
THANKS
I figured out how to rotate my btt tft35 SPI. If you’re using an SPI screen, this should work for you. I detailed it on the btt tft35 SPI GitHub.

Good luck!
