I'm trying to run a Pygame app without using X. I have a Raspberry Pi 3 with raspbian Jessie installed with very few modifications.

The script I'm trying to run is the following:

#!/home/pi/.env/bin/python
import sys, pygame

pygame.init()

c1 = (255,0,255)
c2 = (0,255,0)

screen = pygame.display.set_mode((1360,768), pygame.FULLSCREEN)

rect = pygame.Rect(50,50,50,50)

clock = pygame.time.Clock()

while 1:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

        if event.type == pygame.KEYDOWN:
            sys.exit()


    screen.fill(c1)
    pygame.draw.rect(screen,c2, rect)
    pygame.display.update()

    clock.tick(60)

I have confirmed it works under the desktop environment and with X11, by adding it in .xinitrc. I have succeded in running it "bare" from the command line (provided the resolution is the right one for the screen).

However, I would like to run with a 3.5 inches touch screen as display (https://www.amazon.it/gp/product/B075JFT9SF/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1). It works as well before setting up the touch screen drivers: after that, any attempt to use Pygame result in a black screen and a stuck system. Though I can access via ssh and reboot, any other input is ignored.

I've googled for a couple of days now, but I don't seem to be able to find anything useful. Most results are confused and confusing, citing bugs with pygame and Jessie, and I feel like I'm missing something.

Does anyone know if this is supposed to work, or if I'm skipping some steps?

    the game uses X11 ... why do you expect it to work without X11 ? – jsotola Feb 25 '18 at 23:04
  • Pygame does not uses X11, and it works without it when using a "normal" monitor. My question is why it doesn't with the specified TFT screen. – Maldus Feb 26 '18 at 5:35
