Ubuntu
joystick package

If buttons and axis are not showing up, is it joystick or joydev.ko problem?

Asked by Hans Deragon

If buttons and axis are not showing up, is it a problem with the 'joystick' package or the kernel module 'joydev.ko'? I have a Logitech Driving Force GT wheel and running kernel 3.5.0-44-generic, I have 11 axis and buttons showing up with 'joystick', but many buttons are missing.

I can help out to figure out what is missing to get all buttons working.

Seems to need ltwheelconf.

LTWheelConf is not required anymore with the new kernels; the project has been abandonned since. So the problem lies somewhere else. I suspect 'joydev.ko' since I assume that 'joystick', like games, is only reading data provided by the kernel module. But I would like to have a confirmation before issuing a bug report against 'joydev.ko'.

BTW, I tried LTWheelConf and it did not work.

Hi,

The tools in the joystick package, as you suspect, only use the information provided by the kernel. There might be a trace somewhere in your dmesg output (/var/log/dmesg) from joydev giving the number of buttons detected.

The evtest tool (in the package of the same name) can also be useful when investigating this type of problem.

Regards,

Stephen
