Pygame on full screen & auto start

Hello,

I’d like to have my pygame autostart at boot.
The pygame/python deps are all ok (already succeed to start it through xfce term).
But I’d like to avoid start xfce and work directly with X11.

So I seek for Autostart Options in config menu and and setup to 17 (custom script in foreground & autologin)

Added the following line :

xinit which python3 ‘/home/dietpi/Devel/battleship/game.py’

And I’d like to run into dietpi user.

Seems that /var/lib/dietpi/dietpi-autostart/custom.sh was not executable (this is a bug?) so I chmoded +x it

I see that X11 should work in unprivileged user but can’t get it working.
I added tty group to dietpi user, and added g+rw to /dev/tty0

The error that I have is :

cannot open virtual console 2

Of course I can start it a root, but I’d like to avoid this solution if possible.

Thanks a lot

it might need special commands to start in full screen mode
pygame.display — pygame v2.1.4 documentation

pygame.FULLSCREEN

Yes indeed, the fullscreen flag is already set into code. All code is already working as expected in “conventional” raspbian.

I’d like to transpose it into dietpi.

I solved the previous error I had (cannot open virtual console 2) with the installation of xserver-xorg-legacy but I have another errors: touch screen not working in this mode and the display resolution is a bit weird.

I fall back into “classic” auto login xfce (desktop) to have that. And created a Desktop file ~/.config/autostart/app.desktop

Into that I have touchscreen & sound working, only thing in error is the flickering into pygame.

I check a bit the thing of double buffering but can’t have something working for the moment.

If you have any idea, It’s very welcome !
