whats the axis minimum and maximum?

[LazyDope]

I tested on Windows with a different joystick (though from the same company) and the issue persisted so it seems like it might just be an issue with how the game handles throttle deadzones in general. If I can fix it in linux then that would be great, but I think it would still merit a separate issue.

0 for forward and 65635 for back, however I believe that evdev normalizes all inputs to -32767 and 32767 which it seems to be doing correctly.

[xAix1999]

did you happen to change the dead zone settings and restart the game and or possibly your system?

evdev interacts directly with the kernel so i would change settings and reboot.

I've restarted multiple times since making the changes.

set the throttle in the "back" position and then make the changes. i would probably set the minimum to 0 and maximum to 32k and change the dead zone to 0 instead of it probably going to 16k. you will probably need to make an udev rule to make the changes at boot. though the udev rule will probably be a dirty hack type of solution.

I don't think I can change the min/max that evdev reports to X4, nor the values that my throttle reports to evdev, I can only change how evdev maps the throttle's range to evdev's standard range (-32k to 32k). However this did give me an idea, which is if I set the max value in evdev to twice the actual max, then after evdev it maps to exactly in the middle. Now with bidirectional throttle and it works as intended (back = 0 throttle, forward = max throttle, with some deadzone around 0), if a little hacky.

I also decided that a systemd user service was a lot easier than a udev rule since it'll always be plugged in anyways, so after manually editing the saved calibration file, this is what I ended up with:

Code: Select all

~/.config/evdev-joystick-calibration/ThrustmasterTWCSThrottle.json

Code: Select all

{"2": {"minimum": 0, "maximum": 131070, "analog": "ABS_Z", "flat": 600}, "5": {"minimum": 0, "maximum": 1023, "analog": "ABS_RZ", "flat": 0}, "7": {"minimum": 0, "maximum": 1023, "analog": "ABS_RUDDER", "flat": 0}, "17": {"minimum": -1, "maximum": 1, "analog": "ABS_HAT0Y", "flat": 0}, "16": {"minimum": -1, "maximum": 1, "analog": "ABS_HAT0X", "flat": 0}, "1": {"minimum": 0, "maximum": 1023, "analog": "ABS_Y", "flat": 32}, "0": {"minimum": 0, "maximum": 1023, "analog": "ABS_X", "flat": 32}}

Code: Select all

~/.config/systemd/user/evdev-joystick-cal.service

Code: Select all

excellent! let me know if it works as intended.

[LazyDope]

Seems to be, thanks for helping out!

[xAix1999]

no problem friend

[RPINerd]

I know insanely general, but anything one can do specifically to help?

I've been running the game on Linux since launch and had nothing but good experiences, would love to just be able to give back in some way

[EGO_Aut]

Installed pop!_os linux, steam and x4
Testrun x4 (after 45min shader post processing) was sucesful!

I want to transfer my saves, searched in - (personal directory) + "ctrl+h" .config - can not find egosofts x4 directory

What am i doing wrong? - Warning im linux-noob

Edit: FOUND

personal directory/.var/app/com,v,,,team/.config/Egosoft/x4/xxnumbersxx/save

Huh, weird. Are you using steam's flatpak?

I dont know, there was a install next to a steam symbol, and i installed it default without changes.

BTW: I installed X4 and an old Medival II game.
X4 starts and runs fine, i appreciate 10-15 % more (old win10: ~20 fps vs linux: ~25 fps without graphic problems). I am happy https://youtu.be/ZR-ObdcEGQk - @06:40 old win10 rig - no video under linux atm, sry
But i did not get Medival II started, although there is a "start" in the steam app for this game

Would it be possible to upgrade the used SDL version on Egosoft's side?
Xorg is on the way out and X4 doesn't start with

Code: Select all

SDL_VIDEODRIVER=wayland %command%

launch option on Steam

Some people experienced a performance gain in other games because you wouldn't have to go through xwayland first. And X4 is pretty cpu bound and it could help a bit in late game

I personally tried to replace the SDL .so files in the lib folder but it still doesn't work with said launch option while xwayland works

I'm back in X4 after long pause. I'm now running Linux (EndeavourOS) on PC with 32GB RAM with an Nvidia GPU 12GB VRAM, KDE, Wayland.

Did a long session yesterday and after some (?) hours I got stutter in some places and at some point everything slowed down. Not just the Game but the whole system. I barely managed to fire up btop and there I could see that the system was out of RAM since the X4 process had grabbed all that was left.

Anybody else seeing this?

Is it with 8.0? Please post your system specs (kernel version, steam, etc). A hw-probe would be best: https://linux-hardware.org/?view=howto

Your sda seems to be slowly dying.

Barring faulty memory (which you can test with memtest86+ (for endeavourOS and archlinux, it seems you need memtest86-efi)) it looks like a memory leak. I haven't tested 8.0 yet myself yet, so I can't tell if it's a general issue.

You should do several things:

• Test your ram with memtest86+. Software runs on an infinite loop and will keep testing until you tell it to stop, only one pass is required.
• Make sure you can reproduce the leak. Determine if is it save game related, or if it happens regardless of what you do or how you start a game
• Post your findings in a new topic in this forum, include your system info and a save game if relevant.
