Hi all,
All of a sudden PoE just won't start under Ubuntu 15.10. Previously it worked like a charm, and now I'm receiving this every time I'm trying to run the game

mystic@laptop:~/GOG Games/Pillars of Eternity$ ./start.sh
Running Pillars of Eternity
Set current directory to /home/mystic/GOG Games/Pillars of Eternity/game
Found path: /home/mystic/GOG Games/Pillars of Eternity/game/PillarsOfEternity
Mono path[0] = '/home/mystic/GOG Games/Pillars of Eternity/game/PillarsOfEternity_Data/Managed'
Mono path[1] = '/home/mystic/GOG Games/Pillars of Eternity/game/PillarsOfEternity_Data/Mono'
Mono config path = '/home/mystic/GOG Games/Pillars of Eternity/game/PillarsOfEternity_Data/Mono/etc'
/dev/input/js0: open: Operation not permitted

Changed permissions to 777, still no luck
mystic@laptop:~/GOG Games/Pillars of Eternity$ ls -la /dev/input/js0
crwxrwxrwx 1 mystic input 13, 0 Jan 3 2016 /dev/input/js0

Any ideas?

Problem solved after reboot
