The online racing simulator
Well I'm updating my kernel version in about 5/10 minutes, I'll be updating to 2.6.39 so I guess I could patch that version right?
I built a patched 2.6.38 kernel for 64bit Ubuntu 11.04. I haven't changed anything except from adding the necessary patches. The kernel and headers can be downloaded here:

Kernel image
Kernel headers

You can install these packages by copying it into the same directory and running

sudo dpkg -i linux-*.deb

If you're using proprietary nVidia or ATI display driver, you'll most likely have to reinstall it.
I'll try to set up a more suitable mirror for these files as sharegadget deletes your files after 19 days.
I've installed the kernel heads & image, they didn't seem to make a difference. I'm still getting the same FFB as before but it keeps pulling to the left, I can't play properly unless I turn the force down to 0% or turn off FFB altogether in game.

Edit if you want I can try take a video of what I'm meaning.
That's a bit of a setback. Perhaps I improperly backported the patches. Can you open the terminal, plug your wheel in, run

dmesg | tail -n 20

and post the output?

Expected behaviour is that when you plug the wheel in
1) Your wheel switches to native mode (not sure how you can check that with DFGT)
2) Range is set to 900 deg automatically
3) Autocentering is disabled
4) There is a "/sys/module/hid_logitech/drivers/hid:logitech/<device>/range" file present where <device>=000x:046D:C29A.000y (x and y will vary). You write to this file using "echo 720 > (path to the file)" to change the range.

Does anything of this happen when you plug the wheel in? Also, could you post the output of "lsmod" when you wheel is connected?

I'd be glad for any feedback you can get me, there's still still time till the 3.2 kernel merge window opens.

EDIT: If you're having issues with games played through WINE, please make sure you have the lastest 1.3 version. IIRC Natty ships with 1.2 stable branch of WINE which has serious issues with FFB. You can get 1.3 WINE for Ubuntu here
As requested out from
dmesg | tail -n 20

As for when I plug in my wheel; The following behaviours happen.

Wheel sets to non-native mode;
Only 90* range;
Auto-centering disabled;
There is a "range" (attached) file in
/sys/module/hid_logitech/drivers/hid_logitech/0003:046D:C29A.001E

It seems that it still doesn't enable native mode when plugged in, so I can goto 90* each way without auto-centering and any motor resistance. However as soon as I go all the way to full lock there is a lot of resistance and auto-centering is there.

I'm currently using WINE 1.3.15, I upgraded to it when I changed to the 64-bit version of Ubuntu a couple of days ago, when I installed the kernel heads & image as well.
Thanks for the logs. From what I can tell from dmesg the driver picks the wheel up fine and the wheel actually is switched to the native mode - you can tell that because it identifies itself as 046D:C29A. All Logitech wheels in fallback mode have 046D:C294 VID/PID.

The "range" file contains only one value which is the current range of the wheel. "cat range" should print the current range, "echo 720 > range" should set range to 720 degrees etc, you get the idea.
Can you set the range with LTWC?

FFB in WINE has been fixed in 1.3.19 or so if you can, please update to the latest version 1.3.28 (the PPA a linked should contain it).
I can set the range fine with LTWC, and I've downloaded wine 1.3.28 just now. Although I have to find 32-bit development files to install it
You shouldn't have to compile WINE from sources. Check out the link I posted 2 posts above, it describes how to add a software repository with the latest version of WINE.
If you can set range with LTWC, can you also set it like this? "echo 720 > /sys/module/... .../range"

Just tried it, seems to have worked I think. I'll go check the range file. FFB isn't an issue anymore I have WINE 1.3.28

EDIT: Yes, range is at 720.
Perfect, you should be able to set any range from 40 to 900 degrees like that. In fact, the range should set to 900 degrees automatically, I dunno why it doesn't seem to be working for you... Please let me know if you come across any other issues.
I will do, but just now things seem to be fine
Ok doke, came across another annoyance. Whenever I first load up LFS or pit, the peddles seem to be on full even though I haven't touched them. I notice as soon as I press them down, the problem goes away. Although the brake peddle can stick sometimes.

this seems to be a problem within wine; everytime i toggle fullscreen (or start the game), i have to calibrate my wheel/pedals. hasn't annoyed me enough to look into it :-)
It has occurred to me some time ago that WINE picks up the wheel twice. It reads both /dev/jsX and /dev/inputX and doesn't check if they belong to the same device. /dev/jsX is a legacy interface, has deadzone around the center and requires some calibration. /dev/inputX works much better for me(it only requires the "initial" calibration when you launch the game, but LFS needs that in windows too). If you can, please check that you're using /dev/inputX, you can tell that by moving the wheel or pressing the pedals, axes read from the legacy interface will have a noticeable deadzone around the center if you look carefully.
Can't set range on G27
I use Arch Linux and after today's update, LTWheelConf won't set the range. I usually use -r 270 but now it stays at 900. My guess is that it's the new drivers in kernel 3.2 but we also got a minor bump to Wine 1.37-1.1 so that's not out of the question.

The good news is that echo works.
echo 270 > /sys/module/hid_logitech/drivers/hid:logitech/0003:046D:C29B.0010/range

You're right about the kernel causing LTWC to no longer work. The updated driver sets wheel's range to the maximum upon initialization, so when LTWC returns the wheel back to the kernel, the driver reinitializes the wheel and sets the range back to 900. Setting the range via sysfs is the preferred way now.
Ah, I see. I knew there was a driver for DFGT in 3.2 but I didn't realize it would impact the G27 as well. It's nice to see some proper kernel support. Thanks for all your work on this MadCatX.

Hi,
First of all, thanks for all the work gone into making LFS usable under linux! :-)


I've used the installer on this thread, with wine 1.3.37 instead, this is a Mint (Debian wheezy/sid variant), with Linux 2.6.32-5-686, with a G25.

However the FFB is not working correctly. It seems to be either full-force, or no force at all. Sometimes it's somewhere in between, but it definitely does not feel any similar to FFB on windows.

Any idea what to do to fix it? Please let me know if you need any more information.
Thanks in advance!
A 2.6.32 is a rather old kernel and although I don't recall the history of changes that far back, a recent kernel might be worth a try. Is your force feedback experience better with a native linux game or a testing tools?

Hi, i haven't used the script in ages, so most likely it has done some (now) unwanted stuff (i.e. the udev rules won't be necessary anymore, you don't need G25manage and so on). As MadCatX said, right now all you should need is a recent kernel and wine > 1.3.17.
The script tho installs wine from source, and the launcher explicitly uses that version, so you should not have to worry about that. I updated the script so that it won't install udev-rules and G25manage anymore, and also updated the versions of wine to 1.4_rc5 and LFS to the most recent one. You can remove the udev-rules in /etc/udev/rules.d/ (sudo rm /etc/udev/rules.d/90-*-wheel.rules) if you like.
I modified the startscript, too, so just download and run the installer again. It should work again (with a proper kernel).

Thanks both. I decided to uninstall my old Mint/Debian, and go for a Debian Sid this time (keeping my home directory intact).

Just replaced the nouveau drivers with nvidia drivers, rebooted, clicked the handy LFS icon on the menu, and voila, perfect FFB in LFS :-D
Question, wasn't the patch supposed to be added to kernel 3.2?

I not to long ago update to kernel 3.3, and I was hoping that my DFGT wouldn't need LTWC to set it too native mode, but it still does.

Also when trying to compile LTWC I get fatal errors:

bally@bally-laptop ~/LTWC $ sudo make
gcc -Wall -c main.c
In file included from main.c:30:0:
wheelfunctions.h:24:31: fatal error: libusb-1.0/libusb.h: No such file or directory
compilation terminated.
make: *** [main.o] Error 1

Kernel 3.2 and above should handle DFGT just fine, although the patch has never been tested with that wheel. If you add "hid.debug=1" parameter to the kernel boot line, you should get some extra debugging info in dmesg which should help us figure out what's going on.

You're probably missing something like "libusb1-dev" package, that's why LTWC won't compile.
Will test that out in a second then. What's the dmesg command to gain such info?

grep | dmesg ?

Plug the wheel in and type "grep", the last few lines in the log should tell you if and how was the wheel picked up.

EDIT: Whooops, I was quite tired when I wrote this, the correct command is of course "dmesg" (or you could use something like "dmesg | tail -n 10"). Thanks stan.distortion for warning me
