Hi,

I just bought a new joystick GEMBIRD JSK-420. I could not find any manual for Gentoo, only this one (7 years old):
http://www.gentoo-wiki.info/Joystick

I have (I think) everything in kernel + analog module.

I have:

But, when I start joystick software I have similar message like here:

Thanks for any ideas how to run joystick with Gentoo.

Did you compile in the input layer kernel options for the joystick CONFIG_INPUT_JOYDEV, CONFIG_INPUT_JOYSTICK, and appropriate input driver?

I forgot abut joydev - everything works fine now, so nearly [SOLVED]

My last question - should I use x11-drivers/xf86-input-joystick or maybe x11-drivers/xf86-input-evdev?

After installing I had some strange issues - I couldn't start X, so after some probes reinstalling driver for Intel and then reinstalling x11-drivers/xf86-input-evdev for keyboard and mouse to work helped.

I did install x11-drivers/xf86-input-joystick, as I thought is important, but it was about joydev.

You should only need evdev. Joystick is if you don't use the INPUT layer and make it access the hardware directly.

Many thanks. It works.

The next question - why it doesn't work in War Thunder (is not recognized, even if I would like to try manually set any buttons to any function, pressing any buttons gives me nothing).

I have found 2 topics about joysticks and linux on War Thunder forum, so maybe it will give you a clue, what is going on with my one:
[1] Linux Joystick evdev calibration
http://forum.warthunder.com/index.php?/topic/190391-linux-joystick-evdev-calibration/?hl=%2Bjoystick#entry3663810
[2] Second joystick not recognized
http://forum.warthunder.com/index.php?/topic/192100-second-joystick-not-recognized/?hl=%2Bjoystick#entry3859375

... I am asking as this manual (joystick + Xorg) says
http://www.x.org/archive/X11R7.5/doc/man/man4/joystick.4.html

Quote:
joystick is an Xorg input driver for Joysticks. There are 3 backends available that are used in the following order, if support was found:


- Linux's evdev interface
- Linux's joystick interface
- BSD's usbhid interface

The driver reports cursor movement as well as raw axis values through valuators.


So maybe I should use other than evdev interfrance?

Code:
# dmesg | grep -i Joystick
[15574.956754] hid-generic 0003:12BD:A02F.0004: input,hidraw1: USB HID v1.10 Joystick [5-Axis,12-Button with POV ] on usb-0000:00:1a.0-1.2/input0


I did try this game and joystick works:
Code:
# emerge -s searchandrescue

I have never played that game so I don't know. You may have to use the other interface if it does not use X11, but I thought most games now use X11 but maybe not evdev input...

What's funny is that the same problem existed long ago with input layer /dev/input/mice and old programs requiring /dev/psaux, so now they have the emulation layer for psaux. I suppose joysticks weren't popular enough to need this back emulation.

I've only got an analog joystick hooked up to a computer I don't use at all via the soundcard analog port. After I verified the test program works printing out numbers that correlated to the joystick position I called it a day and it has been sitting there ever since... :(

So I have 2 options:

[1] Easy one - to buy a new one which is in the game on the supported list - but I have no guarantee it will works if there is another problem or...
[2] Richard Stallman way - to find the driver which works or what is the problem (like with the mouse you said above, I remember old times):) Richard Stalman could not use time ago a printer in University, as they did not have a driver (as producer said is out contract). So they have equipment like me, but they couldnot use it (without driver). So he wrote a driver, a made it open under first in the world GNU licence :)

You can run qjoypad to see if your system recognizes your joystic and it's buttons.

It recognizes - the problem might be here - input device (like in my post above):
Quote:
Looks like WT is using X input device instead of pure /dev/input/eventX, so you can configure X to use joystick drivers for X and tell it to use /dev/input/jsX, which can be calibrated thru jscal. Should work fine.


but qjoypad can siumulate keyboard and mouse - so maybe instead of pure joystick I will have keyboard&mouse replaced as a... joystick :)


UPDATE 6am:

I was trying jscal and I have this:
Code:
$ jscal-store /dev/input/js0
Storing joystick configuration requires udev!

so looks like I have to connect joyystick by udev - but how to check how connection looks like now? Is there any command to check if I have Linux's evdev interface or Linux's joystick interface?

the input.x11_driver type is 'evdev' rather than 'joystick' which the other joysticks in the file have.

DAY 2

OK, in the shop I have changed a joystick for a new one Logitech Extreme 3D Pro. I did everything like with the first joystick, but this time I do not have this /dev/input/js0 or similair. Looks like everything is OK, but...

dmesg
Code:

UPDATE 11:13am
OK - I did manage with linux (see bellow), the joystick still doesnt work in the game :(

Quote:
Device Drivers ->
Input Device support ->
<*> Event interface
HID support ->
Special HID drivers ->
<M> Logitech devices



UPDATE 3:52pm

I found it, so the question how to switch form one input system to another?
Quote:
Linux actually has 2 different input systems for Joysticks. The original 'Joystick' interface and the newer 'evdev' based one.

'/dev/input/jsX' maps to the 'Joystick' API interface and /dev/input/eventX maps to the 'evdev' ones (this also includes other input devices such as mice and keyboards).

Most new games will default to the 'evdev' ones. However many of the ones mentioned here (such as jscal, jstest and jstest-gtk) only work with the older 'Joystick' interface making calibration/mapping with those tools mostly useless. 'evdev' doesn't support any remapping or calibration leaving it up to the applications to support it.

OK. It works! :P 8) :P 8) :P 8) :P 8)

I will summarize everything, as there no such information in our Gentoo Wiki and the problem - the modern game cannot see your joystick - is popular, so...

[1] Make sure, you read this:
http://www.gentoo-wiki.info/Joystick (Gentoo Wiki Joystick)

[2] If you have usb joystick make sure you have HID support in your kernel - generic or for your producer (like mine bellow)
Code:
Device Drivers ->
 Input Device support ->
 <*> Event interface
 HID support ->
 Special HID drivers ->
 <M> Logitech devices


[3] Read this

[4] In step 3 above you can see - most new games will default to the 'evdev' ones - so if your joystick works in linux and you have /dev/input/jsX - so you will have to check if (and what) 'evdev' joystick use. You need command lsinput from sys-apps/input-utils.
Code:
*  sys-apps/input-utils
      Latest version available: 1.1
      Latest version installed: 1.1

      Homepage:      https://www.kraxel.org/blog/linux/input/
      Description:   Small collection of linux input layer utils
      License:       GPL-2


[5] Use lsinput and check your joystick:
Code:
# lsinput -v
/dev/input/event9
   id   : 046d:c215, USB, v272
   phys : "usb-0000:00:1a.0-1.2/input0"
   name : "Logitech Logitech Extreme 3D"
   KEY  : [ 12 codes ]
   ABS  : X Y RZ THROTTLE HAT0X HAT0Y
   MSC  : SCAN


[6] I have done this from this website
http://forums.x-plane.org/index.php?s=dd1ab83a4809125918dc66f9a95c16f7&showtopic=60462&page=1

Check your joystick details by lsusb
Code:
# lsusb
Bus 003 Device 014: ID 046d:c215 Logitech, Inc. Extreme 3D Pro


In /etc/udev/rules.d/ I have made this file 99-input-joystick.rules (idProduct and idVendor I took from lsusb)
Code:
KERNEL=="event*", ATTRS{idProduct}=="c215", ATTRS{idVendor}=="046d", MODE="0666"


[7]
- Unplug and replug your USB joystick
- Start the game
???
- Enjoy!!! 8) :)
