I upgraded to the Logitech G29 from the Driving Force Pro just recently, but have not figured out how to set it up properly (I did search). At least LFS can tell what wheel I'm using.

I need help on:
-Clutch axis is recognized in the options, but does not work. Basically no manual clutch.
-Shifter works only auto-clutch, but I can sort of get the shifter to work under manual clutch for only a few gears by holding the upshift button I assigned to (still no manual clutch)
-Wheel rotation and force feedback changes in options has no effect

Many Thanks!

why 0.6P? the most up to date version is 0.6R

How it works for me with G27:
gears:
-set Clutch to "axis"
-set gearshift mode to "shifter"
-assign all 1-6 gears
-select a car with H-pattern gearbox (for ex Lx4, Raceabout)

ffb:
-force strength > 0
-force feedback: "yes"
-in profiler: "allow game to adjust controller settings" (not sure what is excact wording in english) and set rotation to same as the LFS cars

nice

It should be easy to set up, you just have to assign some stuff in controls. Gutholz got it right.
