i rotated my screen through the pi itself
preferences and screen rotation -
@wuermchen there should be an option in the raspi-config program (run from a terminal window) for rotation
sudo raspi-config
-
that does not work
-
@raf yes, thanks. That is where it was

@sdetweil
sometimes i can also solve a problem except for myself -
@wuermchen I think your original problem was in /boot/config.txt where you had spaces around the equal sign for display_rotate.

I found the mistake. The HDMI cable was defective. I installed a new cable and now it automatically detects the resolution. The display is now correctly rotated.
