Debian Linux pitch rotation stutters in DCS

[Wanchos]

Hi i have a problem using my delanclip to track my head in DCS. I can bind my yaw and pitch but the yaw is set as JOY_RY and pitch as JOY_Z. The JOY_Z seems to be the only axis to stutter while the other ones work fine any ideas? I am using libevdev as output.

[Wanchos]

So obviously the axis is output wrongly and if i try with steam input then my pitch becomes the left and right trigger. I probably have to change the output? So when i press the configure button for libevdev it says that it needs read write permission for /dev/input/uinput. Does that mean i have to put opentrack in the root group and give it read write privileges? Thanks for any help!

[Wanchos]

So i tried opentrack in Euro truck simulator 2 and the there was no problem so it might be a DCS problem.

it says that it needs read write permission for /dev/input/uinput. Does that mean i have to put opentrack in the root group and give it read write privileges?

No.

Your distro might already be taking care of it. First try

ls -l /dev/input/uinput

There might already be an input or similar group to add your user into. However, the device node might not exist at all and instead be located at /dev/uinput (in which case it needs a symlink).

In the short term,

chmod 666 /dev/input/uinput

and see if it works at all ingame.

Then you can start figuring out how to add a udev rule which is the proper solution here.

Hello thanks for your fast answer. For me uinput is in /dev/uinput. I tried to chmod uinput but have the same issues do you have a recommended solution for me?

[sthalik]

Try this as root:

ln -s /dev/uinput /dev/input/uinput
chmod 666 /dev/input

[Wanchos]

Try this as root:

ln -s /dev/uinput /dev/input/uinput
chmod 666 /dev/input

I tried your suggestion and dcs could not detect any of my devices (hotas, opentrack etc) after running the commands. Is there something else that i could try? Btw i also want to clarify that my opentrack install is in my home folder just in case that is relevant.

[sthalik]

Was DCS previously able to use your HOTAS controllers? Is it the case that making uinput available suddenly makes it unable to detect anything?

[Wanchos]

Yes DCS was previously able to use my hotas controllers and detect opentrack. Making uinput available in the way you suggested seems to make DCS unable to detect anything.

[sthalik]

You could try making a virtual joystick using the xboxdrv program and see if DCS detects it, without doing the uinput thing that I suggested earlier.

[Wanchos]

I will give xboxdrv a try when I have some time otherwise I will try to see if the same thing happens on other distros. In worst case I will have to install windows I guess. Thanks for your time and help!
