help calibrating steering wheel

[m8118]

(I looked for previous posts...)

My logitech cheap wheel has a "large zero center" (I don't know how to call it -
doesn't start turning until I rotate it a few degrees)
this makes it impossible to have any fun...
I confirmed the "large zero center" with jstest but I has able to calibrate it with jscal and now jstest does show immediate response to smallest action on the wheel from the zero position.
however while playing VDrift I still have this large zero center...
I saw reference to the joystick/calibration menu but it's not there...

So, is ti possible to calibrate my driving wheel?
Thank you,
Antonio

...

I installed speed-dreams and the wheel works fine on that...

(I don't known what that means... or if it helps...)

VDrift gets its data from SDL. If jstest works properly, then VDrift should too. A few things to try: in Options->Controls set Speed Effect on Steering to 0%. In Options->Controls->Joystick Options make sure your joystick type is set to Wheel.

thank you!

Unfortunately I have both Speed Effect on Steering to 0% and the joystick option set to wheel...

jstest only works correctly after a run of jscal to calibrate the wheel (I guess until the next system reboot - not sure).

I just Google for "SDL joystick calibration" and found a few discussions on that.
Is it worth while to pursue that or is it completely of base?
(I just got the source code a few days ago... and I'm not familiar with SDL...)

Ooh, here we go:

Sounds like a bug in ubuntu or SDL. I recommend the SDL_JOYSTICK_DEVICE=/dev/input/js0 (or whatever jsX corresponds to your wheel) solution.

AH!



still have to use jscal - I guess that's the intention (saw that in some other post)

thank you!
