Logitech G25 does not fully work with Ubuntu

[Richie Ward]

I own a Logitech G25 steering wheel.

The steering wheel paritally works under gutsy and hardy (Throttle and brakes, steering.. but there are some big issues with it.

a) It only supports 11 buttons.. the G25 has much more than 11 buttons.
b) The clutch pedal does not work at all..
c) Only first and second gear (buttons 10 + 11) work.
d) Force feedback isnt working, I have tried ff-utils from sourceforge.net

About wheel functionality - i think it is not ubuntu but upstream problem: http://vdrift.net/Forum/viewtopic.php?t=866&postdays=0&postorder=asc&start=0
About force feedback see Bug #246952

2.6.28 should have much improved support for this hardware.

[Christophe Borivant (christophe-borivant)]

This device needs a userland utility to switch to its full "native" mode.
When switched to "native" mode, all buttons and axes are useable.

The kernel also needs to be patched as when the wheel is switched to native mode, it changes its USB product ID.

I wrote a little userland utility (G25manage) and the kernel patches for 2.6.27 and 2.6.28. The patches have been sent to Jiri Kosina who's the maintainer of this part of the kernel.
The patch has been accepted and included in the 2.6.30-RC5 kernel.

The userland utility code probably needs to be analysed by a real good C developper (that I'm not) but at least, it works.

The kernel patch is really safe as it doesn't change any logic but only adds the "native" mode product ID.
I use such patches since a least 2.6.25 ( at this time, I was running Gentoo Linux )

You can have a look here (2.6.27 an 2.6.28 patches are provided) :

Christopher, thanks for sending the kernel patch upstream and getting them merged. The kernel for Karmic will target the 2.6.31 kernel. Currently the 2.6.31-2 karmic kernel is available for testing. Since you mentioned the patches were merged into the 2.6.30-rc5 kernel these should already be available for in the current Karmic alpha kernel. Marking this Fix Released for now. Thanks.

With force feedback and native mode working?

[Brendan Smith (apage-apage)]

Has there been any update on this for Ubunto 10.04. When I try to use it in games I can set it up but the ste3ering is very sloppy and the force feedback is just plain weird. I have messed around with all the settings i possibly can in quite a few games and still no success. I should ad I have tried playing all t he games with all configurations I can think of from in wine and playonlinux.

Any help at all is greatly appreciated.
