[SOLVED] logitech joystick moves the cursor

benslice · 2014-08-08 04:10:34

Hello,

My logictech joystick moves the cursor. For most, this means they have xf86-input-joystick installed (a la)
https://wiki.archlinux.org/index.php/joystick

but I do not have that package installed. Nor do I have any of the files that come with that package. I've played with a number of different input devices over the years that may fool with the cursor (apple trackpad, ati remote, xbox controller), but I'm pretty sure I've uninstalled everything (for example, the joystick package was installed at one time). The same joystick works properly on another arch install (on a different computer). Is there a way I can trace what's going on? Can I find out, for example, which kernel module is sending mouse events to X? I've looked at DMESG and which kernal modules get loaded when I plug it in, but I can't seem to detect any differences between the computer that works and the one that doesn't.

I'm trying to play Kerbal space program, and the joystick does send the appropriate signals, but in addition it moves the cursor.

thanks

What Desktop Environment / Window Manager are you using?
Are you using Compiz?

I've been using arch for years now, but I'm new to the forums, thanks for the reply!

On my laptop (which works) I'm running gdm/gnome-shell, and on my desktop (with the problem), I'm running slim/fluxbox.
When I switch the desktop to slim/gnome-shell however, I see the same broken behavior.

Oh, and BTW, the joystick is a Logitech Extremem 3d Pro.

Check /var/log/Xorg.0.log maybe.

That log might be in ~/.local/share/org if you are running a rootless Xorg.
But do look at that log and see if it is processing the event node for the joystick as a mouse. If it is, we can fix that
If you like, post the log here, but be sure to use code tags. It is pretty big. Even better, use pastebin.

Yes, here is the output of the X log when I plug the joystick in. On the other (working) machine, there is NO output to the log when I plug it in.

Are evdev and XINPUT doing different things here, or are they tied together?

Also, the "Applying InputClass "trackball"" seems strange to me. It may be hitting an xorg.conf file I'm using for my trackball (second insert below), but I'm using a very specific identifier for the trackball so I would think it that it shouldn't match the joystick.

Ok, I think I've actually fixed it. I was under the impression that specifying an exact MatchDevicePath would mean my trackball config would apply only to my trackball. But it seems that the rules you specify are "sufficient" but not "necessary". So, while my trackball does match that rule, so might a bunch of other junk. (like my joystick) This is very useful, but it seems silly that you can't supply exact matching rules for a single custom device. I'd be interested in how to do that if anybody knows. Maybe you have to do that deeper down in udev or evdev.

I fixed the problem by adding a joystick catchall as a final rule and set the Ignore option so that Xorg doesn't touch it (or rather it un-touches it after loading the wrong rule). I modeled the section on the catchalls in /etc/X11/xorg.conf.d/10-evdev

My trackball rule is in /etc/X11/xorg.conf.d/40-kensington.conf

So I put the following in /etc/X11/xorg.conf/50-joystick.conf

Section "InputClass"
        Identifier "evdev joystick catchall"
        MatchIsJoystick "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option "Ignore" "on"
EndSection

Thanks for the help!
