I’ve spent an hour trying to get the Hyperpixe working with Raspberry Pi Bookworm Lite. I’ve encountered two very basic issues that appear to be fatal to my project.
Problem #1: Can’t rotate console display
I’ve tried about 12 different ways of rotating the console display: dtoverlay=vc4-kms-dpi-hyperpixel4:rotate, dtparam=rotate, display_rotate, display_lcd_rotate, etc. None of them do anything. The Hyperpixel refuses to boot in anything except its native portrait mode.
Problem #2: Can’t get KMS driver working with pygame
After installing pygame via pip and setting SDL_VIDEODRIVER=kmsdrm, pygame reports being unable to find the kmsdrm driver.
I’m nearly at the end of my patience and planning to return this display to Adafruit as a defective product due to inadequate driver support. If anyone has any advice before I do so, I’m willing to give it a shot.
