I encountered a really annoying issue: the joystick deadzone is not working at all. I tried with both a Logitech Force 3d Pro and X52 Pro and it makes absolutely no difference change the value from 0 to 100.

To make it even worst, with the X52 Pro it seems that the deadzone is 25%, making very hard and annoying to aim at something.

I made a video to show the issue: https://youtu.be/zERDrr9Y108
And another where you can see the evtest-qt and jstest-gtk output: https://youtu.be/5pNve4vzogQ

I found also several other issues with the detection of some button and axis on the X52 pro. Most of them are detected correctly, but some, like the all the buttons from 33 to 39, are recognized as POV directions, like it was the main POV on the stick. The same buttons are correctly recognized on evtest-qt (/dev/input/eventX) and jstest-gtk (/dev/input/jsX).

Should I report all the issues here, create a separate post, send via email or is there an official tracker?

[Toidiboy]

JD reporting here should suffice, the devs are veey active in here and will pick things up/reply to issues.

BTW good work on debugging the issue, I have had a few problems with my HOTAS as well. Quite sure this will help the devs rectify the issues.

Some feedback after serveral hours playing on my ancient 1.0 savegame, wich has a couple hundred hours and using 40+ mods atm.

Issues related to the Linux beta:
- Same issue as radcapricorn mentioned with external camera keybinding controls not working. Only mouse center-click panning works.
- Same issue as _JD_ mentioned with setting 0 deadzone. Reducing does have some effect for me but setting 0 would compare to about 10 in the windows version I guess.
- As mentioned in an earlier post, extensions only works when files/folders are lower case. When changed all works as expected, even more complex ones as ashipmod, xrebirth effects etc.

Performance:
Noticeably better than the windows version with the same settings, I'm impressed..
Had some garbled UI and a few CTD with Vulcan OOM warnings initially, not surprised since my GPU are barely mimium spec. After closing browsers etc this have not happened for many hours. With windows i had to restart the game roughly every 2-3 hours when the UI got more and more garbled, not seen this for a while.
Also little to no stutters in general, even when lingering in Argon Prime - didn't have to teleport to the fringes of the universe to do empire management which was nice.

System/hardware:
Mageia6 on an ancient I5-3570K@3.4GHz CPU, 16G RAM, GTX780 (3Gb), 418.43 driver. Joystick is a true relic but nice sidewinder pro.
Some graphics info: Fullscreen, 1920x1080, FXAA High, Adaptive Vsync, modified ultra preset with reduced lod/effect to 50, low glow, no distortions.

I'm having trouble figuring out the source of this bug since it locks up my system and I don't have a second computer set up right now. Nothing that seems relevant is appearing in my system logs, though I'm happy to upload them if you want. Steps to reproduce:

1. Launch X4 windowed.
2. Exit using the little red x in the top right corner of the screen. (You can start a game first, if you like, but it's not necessary to cause a crash).
3. Reboot your computer since your computer no longer responds to input.

Ubuntu 18.04 with Nvidia proprietary drivers version 415.
No getting to another TTY, no mouse movement, no keyboard, nothing. It sounds like it might related to apcolvin's issue, but I'm honestly not sure since I'm not positive what issue he was describing. But X server screen/keyboard lockup definitely fits the bill. Having done a fair bit of work with Linux, my best guess is that exiting out without using the menu option doesn't do cleanup (since it may use the default termination signal handler if another one is not provided), and thus the GPU is left stuck causing X to stop responding. But that's complete speculation.

DxDiag for my system which is below minimum specs in terms of VRAM, but I highly suspect that is not the source of the bug; if someone else could confirm, that'd be great.

Also, unrelated and minor question about the X Rebirth catalog tool. Any chance we could get a Linux binary for the XRebirth catalog tool? Obviously, if it's a significant amount of work, probably not worth doing, but I was wondering if it actually depended on Windows & Windows build tools or if we just had only seen a Windows executable distributed due to historical reasons.

Thanks guys, I really appreciate the Linux support! One less thing I need to use Windows for! And sorry CBJ, I'm sure you're getting sick of me.

A follow up on this - it happens sometimes when using Exit to Desktop too. Still trying to find anything related from the logs...

A more minor bug - custom ship logos seem to be broken on Linux. I put them next to the save folder (in .config/Egosoft/longnumber/logos/) and I get squares in the menu, but they're blank. The preview and actual ships both show the Da Vinci man logo instead (the one where the man is filled in). Nothing at all in the logs outside of previously mentioned minor log messages from startup. Tried .png and .dds.
It's maybe possible that this is related to the uppercase name thing people have been talking about due to the particular logo pack I was trying out using upper case names for its logos, I'll take another look at it tomorrow. Either way, it's a linux issue - the logos in question work just fine on Windows.

Do external view controls work for you guys? I've tried both numpad (with numlock on and off) and shift+mmb in F2 and F3 views with no luck.

F1 F2 works, but tried pushing F3 F4 and it does nothing... + with F2 view i tried NUMkey_123456789 and it don't look cockpit or change ship external camera view.

My logo works fine (png, lowercase letters). Though I wouldn't think case matters here. Or rather, I'd expect it not to.

Thanks for confirming!

Thanks for confirming. F3 is the target view, i.e. you have to have a target and I think it needs to be no further than a certain distance.

Thumbs up!

Pretty shocked to find it worked out of the box at a stable 60fps (except shipyards) on ultra with a gtx970/fx8370/ubuntu 18.10/xb360 controller (could do with more menu navigation). Game is amazing, RIP x3.

[StarTuxia]

Is there a way to remap joystick axis in the control settings?
The older games used to have Xn_config binary which allowed this, but X4 doesn't have that, and remapping with jstest doesn't seem to make any difference?

It would be good if you could select two Axis assignments and swap them.

I have an old ST290 PRO, and the X/Y axis are assigned for strafing, how can I reassign them for roll, pitch, yaw, etc?

Thanks

I edited the inputmap.xml manually and assigned the axis where I wanted them. They don't all show up in the control UI now though, but they do work

Awesome, I am editing that file too. Hope it goes right lol. I noticed Vive and Occulus entries too...

Edit: Got it to recognize the axes via movement without editing. Took of that gamepad option and then it seemed to work, also made sure no controllers were left empty in the manage controls.

I installed the AMDVLK package (version 2.63.1120.g81fd878-1) but really have no idea what it does. I would highly appreciate help in that regard.
Also, if it is fixed in LLVM 8.x and mesa 19.x, I'll wait and not install mesa-git for example. I waited for X4 since its release. I can wait a bit longer. I'm just happy that all my Linux brethren are able to play

You can use differrent Vulkan driver by changing VK_ICD_FILENAMES environment variable. Go to /usr/share/vulkan/icd.d directory, there should several json files, notabl radeon_icd.x86_64.json and amd_icd.x86_64.json. Their names may slightly differ on different distros, but the one with "radeon" is Mesa's RADV and one with "amd" is AMDVLK. In order to use AMDVLK with X4 you need to edit command line parameters in the game's properties dialog in Steam and put following there:

Code: Select all

VK_ICD_FILENAMES="/usr/share/vulkan/icd.d/<AMDVLK's json file>" %command%

With my RX 580 AMDVLK offered better performance than RADV.

Hi I just purchased X4: Foundations and am currently downloading it. I will post any bugs or crashes I may encounter. Thank you for the Linux port, it's much appreciated!

My logo works fine (png, lowercase letters). Though I wouldn't think case matters here. Or rather, I'd expect it not to.

Linux filesystem handling works differently than windows: Linux is case sensitive, Windows is not (even though NTFS knows about case, the API's on top ignore it);
This means that a config-value of "mylogo.png" will find "MyLogo.png" on Windows, but it won't on Linux.

For XR I wrote a detailed guide how to handle case sensitivity for mod-compatability, it seems it can be recycled for X4

[radcapricorn]

Linux filesystems work differently than windows: Linux is case sensitive, Windows is not;
This means that a config-value of "mylogo.png" will find "MyLogo.png" on Windows, but it won't on Linux

Sigh, here we go again...
a) That's wrong. NTFS is case sensitive. Windows file handling API by default ignores that.
b) There's no config file. There's just an image file. To get at which the game has to read the directory. Which will not yield an incorrect file name. Ergo, in this case the case shouldn't matter. If it does, that's a bug.

Ok, I did some more tests and it seems a Linux related issue: I rebooted on Windows 10, installed X4 and tested the X52 Pro and the deadzone slider is correctly working: I was able to feel a huge difference going from 25% to 0%.

I copied the Windows' inputmap.xml to the linux config dir but, even using that, the deadzone slider is still ignored.

CBJ, timon37: is this issue accepted on your side? Are you able to reproduce it with your Joysticks?

I was really hoping to be able to play a little this weekend

a) Whoops, I don't intend to spread mis-information! Is my edited version OK?

b) during my many hours of testing in XR, I found that lowercasing all filenames fixed basically all problems, even if the filename should have an uppercase letter based on the "real" gamefiles they modded/replaced. My (personal, uneducated) guess is that there is some form of case-folding going on in the game internals, so even if the directory-traversal would give the correct "PathName", the game still won't find it because it keeps looking for "pathname".

P.S. I just read back through the old thread; thanks for pointing out the .cur<->.png issue back then!

hi, do you have the gamepad's mouse emulatiom cursor on map ? i not have it

edit: anyone with xbox pad one or 360 can confirm please ?

Yeah, it would seem that the game loses the real file name somewhere along the way. I've just tested: put an image with uppercase letters into the "logos" directory. Just as in Cg089's case, the game displays an additional "empty" logo. Still, I maintain that in this case the case should not matter at all, and that behavior is a bug

Hi there,

I'm one of the RADV developer.
I have just played the game a bit using latest llvm/mesa on my Vega 56, everything seems fine.

Can you explain how to reproduce the GPU hangs (ie. mesa/llvm versions, chip, steps) ?
Can you also explain how to reproduce "Graphical glitches on lockboxes and jumpgates on radv" ?

Thanks a lot, I would be glad to help.

I can confirm that issue using a T.16000M. Fighting against S/M-Ships is now a lot more... thrilling


Apart from that: Many thanks for the Linux Port! Good works. The game worked out of the box with my from Windows imported savegame (1.0), even with an experienced better performance of the map (less input lag, nearly same, sometimes a little bit more fps than on Windows).
