... Avec ma config, je peux faire tourner X-Plane en haute qualité ? Quel serais les point négatif ?

oui il fonctionne en V10 , par contre il faut à chaque fois débrancher/brancher la fiche USB.

The Joystick subsystem of X-Plane has been rewritten in 10.10. The reason for the rewrite is that we now talk directly to the hardware instead of going through the operating system's paths. What we get out of this is a complete picture of what the hardware actually is. What we knew in the past was "this thing has some buttons and some axis" but now we know EXACTLY what it has and what they're used for...every last detail. This will allow us to do some fancy things with hardware moving forward.

This works fine on Windows/Mac however it's a little complicated on Linux.

Here's the back-story. Linux is a multi-user operating system. You can be doing your taxes in quicken on linux while 12 other people are also logged into a linux shell on the same com****r but remotely from 12 other countries. On linux, hardware devices like keyboards, mice, joysticks etc are directly accessible from the shell. You can sit there and watch the data flow by you. What happens if you're typing in sensitive information and the other users have access to your device watching what you type? That's a security issue!

Because of this, the Linux operating system locks down permissions on all external hardware. What this means for us is that X-Plane will NOT have access to your joystick to read from it. It will get a "permission denied" response when trying to read from the joystick. There are exceptions though! Joysticks are not risky devices so most linux operating systems will lighten up their security on them. The question becomes "what is a joystick" though. How does it know the difference between a joystick and a mouse? Well a joystick has at least two physical axis and one or more buttons. Things that look like that will be exempt from security so MOST devices just work fine. But wait...a Cessna trim wheel has 1 axis and no buttons. That doesn't look like a joystick! A set of rudder pedals has 3 axis but again, no buttons. That doesn't look like a joystick. Because of this, these types of devices never get the security exemption and therefore are invisible to X-Plane.

It's up to you, the USER, to tell the operating system that these devices are in fact safe for other programs to use. Do this by writing a UDEV rule. This is fairly simple to do for an average Linux user and once done your devices will work fine. The rule simply tells Linux "When you see this Cessna Trim wheel, allow other users to see it, it's safe".

Here's a blog post that has more information on the topic:



This is not a bug in X-Plane but a permissions issue with the operating system. The way to solve it is to write a UDEV rule for their devices. You can read the blog post for information on how to do that.

The latest X-Plane 10.10 beta update may provide a fix if any problems are due to an X-Plane earlier version bug. Be sure to save your current version of X-Plane and update a second copy of X-Plane to test the beta (Including all third party add-ons) before making the new beta update your main X-Plane folder. (It can take time for some third parties to make their code/aircraft compatible with the latest beta X-Plane 10 code.)

See attached tips from the user manual for installing/tuning/updating X-Plane 10.

je vote pour ici, quand la v 10.10 sera "officiel"

Suite et fin pour mon problème de palonnier Saitek qui est reconnu avec Xplane 9, Xplane 10.05 mais pas avec Xplane 10.10b8.
J'ai d'abord envoyé un mail au support Laminar qui m'a très vite répondu (voir à la fin de ce message).

La refonte du système de gestion des joysticks ne simplifie pas les affaires des Linuxiens, surtout pour les débutants, car il faut créer une règle UDEV comme évoqué ici : http://developer.x-plane.com/2012/07...stick-trouble/

Si d'autres sont dans le même cas, voici comment faire en s'inspirant de cette discussion : http://forums.x-plane.org/index.php?showtopic=60462

1) lancer la commande lsusb pour récupérer la liste des périphériques USB :
2) chercher le joystick non-reconnu sous X-Plane 10.10. Chez moi, le coupable est ici :
=> Noter les idVendor et idProduct : 06a3:0763

3) créer un fichier nommé 99-input-joystick.rules dans le dossier /etc/udev/rules.d
4) Copier cette ligne en adaptant les identifiants vendor et products récupérés plus haut :
Puis sauvegarder ce fichier.

6) Débrancher/rebrancher le joystick, il devrait maintenant être visible sous Xplane 10.10.
