Hey - Thanks for putting the time into improving the FF experience for linux sim racers. When I installed, there is a message in dmesg complaining that the kernel is tainted. Details are below.

OS: Xubuntu 19.10 Kernel: 5.3.0-23-generic dmesg: [48323.780734] hid_logitech_new: loading out-of-tree module taints kernel. [48323.780763] hid_logitech_new: module verification failed: signature and/or required key missing - tainting kernel

This is normal. Your kernel becomes tainted because the module is not in the kernel sources. See https://unix.stackexchange.com/a/116976

Most of us don't see this message because the kernel is already tainted since we load the nvidia propietary module or some other 3rd party module at boot time.
