I am running Linux Mint 17 on a very capable computer.
X Plane 11 runs great, however, the joystick runs completely out of calibration once the simulation begins and you attempt to fly.
Some facts about this issue:
1.) The joystick runs perfectly fine on the same computer under Windows 10 with X Plane 11.
2.) In Linux, running the program 'jstest-gtk' reports perfect calibration.
3.) In X-Plane 11, the Joystick configuration shows my Joystick (Logitech Extreme 3D Pro) and the calibration in X-Plane appears to be working normal (until you actually try to fly.)
4.) I have followed this information: http://www.x-plane.com/kb/my-joystick-or-yoke-isnt-working/
The ailrn,elev, and ruddr numbers are way off.
5.) The joystick is the only device shown under Joystick Devices.
I am unsure what else I can do to rectify this issue. X-Plane 11 is completely up to date with all updates.
