1- it works! No more freezing! Thanks a lot! For future references:
add the following two lines to /etc/security/limits.conf
* hard memlock unlimited
* soft memlock unlimited
then reboot the system.
2- For the sake of clarity, the game works but save files must go in ~/.config/VerdantVillage or in ~/.local/share/VerdantVillage and not in ~/VerdantVillageThanks for everything and keep it up! Thumbs up!
