PS3 Controller Left Analog Stick & FPS Camera Issue [Linux/Ubuntu 14.04]

[enter_vinput]

After multiple threads not receiving any response, I'm going to cut the fluff: camera doesn't work properly in FPS games for my PS3 controller. I first thought it was just Portal, but then Sanctum 2 had the same problem.

Example: when trying to move forward, I will move forward, but the camera will move as though I moved the right stick in the same direction. This results in me moving forward while staring at the sky, and vice versa with backwards and the ground. Makes FPS games unplayable with a controller.

Trying a "Southpaw" configuration in Sanctum 2 "fixed" the problem (as in, the problem didn't carry over to the right stick which now controlled the player and the left stick was acting as it should, as in, the issue is isolated to the left stick with something about a z-axis) but gave me the problem of handling an entirely new and unfamiliar control scheme.

Controller works with other non-FPS games with no problems, specifically The Binding of Isaac: Rebirth & Trine.

Had xboxdrv & sixad installed, and recently removed them thinking the issue was a result of them, which was not the case.

I'm a Linux fan, but also a Linux idiot, so a simplified direction process for either a solution or more info you may find heplful would be much appreciated.

For me this was happening with xbox 360 controller. Turns out the left stick was also controlling mouse cursor. That's why the camera was also moving. To fix this, I created a new file /usr/share/X11/xorg.conf.d/50-joystick.conf. Content below:

Section "InputClass"
Identifier "joystick catchall"
MatchIsJoystick "on"
MatchDevicePath "/dev/input/event*"
Driver "joystick"
Option "StartKeysEnabled" "off" # Disable mouse support of joypad
Option "StartMouseEnabled" "off"
EndSection


After restarting the system, I launched the game again and everything was working fine.
