I have set up neXt with Interlink DX on my win 10 computer and it works awesome! Really impressive sim, thanks.
However if I try to fly on my linux laptop (dell xps, ubuntu 21.04) then controller doesn't have enough resolution: it completely misses tiny bumps (large moves are ok). I tried changing deadzone/threshold to no avail. If I open input monitor on windows - I see some jitter in inputs (+- .05), while on linux it is completely stable without any noise.
Any idea what to try? I'd love to have a portable sim option.
Do you think spektrum dongle will have a better resolution on linux?
I think you need to reduce the dead zone in your joystick driver. In your case, the system setting overrides the dead zone setting in the simulator (Settings > Input device).
This is the preferred way of use: -> To configure the joystick or remote control, start the program 'joystick_config_x64'. The SDL2 libraries will be installed and then the joystick configuration program will be started. Follow there the instructions. When you are finished, the controller map will be saved.
-> Start 'neXt' by clicking onto 'run_neXt_x64'. This first loads the controller map and then starts the simulator. Go to the tab Settings > Input device and click on 'Start Calibration'.
-> If the joystick configuration program does not work for you, you can reduce the dead zone using the terminal before starting the simulator. The example shows the parameters for an RX2SIM. Adjust the device name if necessary: evdev-joystick --evdev /dev/input/by-id/usb-RCWARE_RX2SIM_Game_Controller_8D8B128C5751-event-joystick -d 0
joystick_config_x64 doesn't work on the latest Ubuntu. I managed to compile your test app manually after installing sdl2, but the app UI is really confusing since it expects a gaming controller.
