Joystick not recognized

Hi,

On LinuxMint 22.3, I installed Oolite 1.92.1 from its Flatpak (I guess the one of the LinuxMint software manager is the same as the upstream one).

I have my Saitek P880 joystick not recognized by oolite (the joystick menu is gray). It is recognized by the host, though. I can play other game and jstest-gtk recognized it entirely.

About a decade ago, I used to play with Oolite with this joystick.

The clues at Oolite wiki did not help.

Ideas?

Can't post to the OOlite forum

Thanks
