I have a strange problem with the steam controller, generally it is working fine but not with The Witcher 2 where doesn't appear and on Tomb Raider: with this game it has a strange behavior, while I hold L2 and move the controller, it moves the menu and it is the only thing that I can do :) On past it has worked fine on TR.
It is an almost clean installation of Ubuntu 17.10 (but on Unity), I copied some folder from the old pc i.e. the steamapps. I installed steam with apt and also the steam-devices pkg that brought the /lib/udev/rules.d/99-steam-controller-perms.rules file, without this pkg steam doesn't show any controller. I'm on the stable release of steam.
I tried with big picture and also loading a controller configuration from the community but nothing has changed.

Any suggestion?
