Linux Support (Beta)

[ironwill]

Short answer because of the network code.

Kerberos and libssh2 are libs mainly made for remote and auth stuff, working as a wrapper around console mechanisms. I myself wrote a lot of projects using these. They are quite hard to use outside that purpose, lets say for plain data transfer. It's so much easier to spawn secure sockets using open-/libressl and use that for data transfers. And the ssl libs are linked too, so asking why libssh2/kerberos is used gets a bit more urgend. I'm asking because I'm a developer in this field for 20+ years now and damn well aware what can be done using this stuff.

[Brianetta]

The network features of the game authenticate against your account on this forum. Presumably, these libs are required to do that. Kerberos allows the game to get a ticket and stay logged in, while ssh can do whatever ssl does, considering that it's all self-certified.

[timon37]

Those are possibly not needed, but stuff's normally compiled and linked with minimal changes/configuration. I'll take a look into it, when I get a chance. Similarly our ffmpeg could be slimmed down a lot.

[d3drocks]

Steam is required to run the game.

Will this be a requirement for the final release? You are selling X4 on GOG (which i prefer as it is DRM free). will a Linux version be available there? Steam is simply not an option for me.

[CBJ]

The final Linux version will also be released on GOG, but we will not be making Beta versions available there for Linux.

The final Linux version will also be released on GOG, but we will not be making Beta versions available there for Linux.

OK. Thank you for clearing that up. I've been holding out on purchasing X4 until I could get that cleared up!

That is a quite interesting and, well, uncommon setup for a game. Do I see this correctly? The Windows version seems to use quite a different setup (took a "quick" look using IDApro).

Game not starting.

This means you have a non-working Vulkan setup. Take a look at this site for a solution:
https://github.com/doitsujin/dxvk/wiki/Common-issues

for the lazy:

Next, make sure you've got vulkan libraries installed on your system.

On ubuntu: sudo apt-get install libvulkan1 libvulkan1:i386

On arch linux: sudo pacman -S vulkan-icd-loader lib32-vulkan-icd-loader

If you're on AMD, you'll also need to install the vulkan driver separately.

On ubuntu: sudo apt-get install mesa-vulkan-drivers mesa-vulkan-drivers:i386

On arch linux: sudo pacman -S vulkan-radeon lib32-vulkan-radeon

It's for DXVK, but should be worth to look at for any Vulkan game.

[Mortifer]

Code: Select all

sudo apt-get install libvulkan1 libvulkan1:i386
sudo apt-get install mesa-vulkan-drivers mesa-vulkan-drivers:i386

Thank you. This solved the problem.

I got to try it and I'm happy to say that I didn't encounter any issues with the game for the 1 hour I played it. Performance looks good.
My only complaint is that it takes longer to alt-tab compared to Windows. On Windows it is instant, on Linux it takes a few seconds for both fullscreen and borderless modes. Might be something to do with my setup, but I didn't have time to test it extensively.

PSA for Linux users with Nvidia Optimus laptops: you have to switch to discrete graphics to play this game with the proprietary driver, you can't use dynamic switching (EDIT: see first solution). It's not the dev's fault. The Nvidia driver doesn't support dynamic switching on Linux and bumblebee (optirun and primusrun) don't support Vulkan. nvidia-xrun works partially, but if you switch TTYs while the game is running the game will freeze and segfault (known issue).

Solutions:

• New: use primus_vk. It's a bit fiddly but it works! Set the launch option to

  Code: Select all

  ENABLE_PRIMUS_LAYER=1 optirun -b primus %command%

  With Vsync off the performance is very close to using the Nvidia GPU as primary.
• Use the Nvidia GPU as the primary. Some distros like Ubuntu and Fedora have a tool to switch between the Intel and NVIDIA GPUs. If your distro doesn't have such a tool you can do it manually by following this guide: https://wiki.archlinux.org/index.php/NV ... ing_nvidia.
• Use the open-source driver which implements proper dynamic switching. I didn't test it so I have no idea how it performs.
  EDIT: I didn't know that nouveau doesn't support Vulkan.
• Use nvidia-xrun but don't switch TTYs while the game is running. Guide: https://forum.manjaro.org/t/how-to-use- ... xrun/56260.

I use the first solution. In my case I want dynamic switching when not gaming so I have bumblebee installed. When I want to switch to the Nvidia GPU for gaming I have to disable bumblebeed.service after performing the steps in the linked guide, and re-enable it when I want to switch back. (Edit: with primus_vk this is no longer the case )

Hope this helps someone.

I know my version is not officially supported, but maybe this is a more common problem.

Starting the game works fine, it seems to do its thing... and then EVERYTHING simply hangs. Can't even access tty2. But the music keeps playing
I managed to get to the main menu ONCE, thought I could change the AA settings and whatnot before starting a new game and ended up with the same problem.

As mentioned in the main post, I already tried waiting for about 20 minutes in hope it comes back... but nope.

A more verbose log could help maybe? How would I obtain that? Or am I simply missing some dependency?

Bug 1:
If you select ships with the mouse in the map, the selected ship get's deselected after 1-2 seconds.
Wenn man mit der Maus in der Karte ein Schiff auswählt, wird es innerhalb 1-2 Sekunden wieder abgewählt.

Bug 2:
After switching to the desktop (alt+tab) and back again, the game window is not fully restored and you can't select anything in the game.
Geht man mit Alt-Tab in den Desktop und zurück ins Spiel, wird das Spiel nicht vollständig angezeigt und man kann nichts mehr im Spiel anklicken bzw. auswählen.

Edit:
These bugs only appearing if you stay in the desktop some while - about 10 seconds.
Diese Bugs treten nur auf, wenn man etwas länger im Desktop bleibt - um die 10 Sekunden.

The final Linux version will also be released on GOG, but we will not be making Beta versions available there for Linux.

that is a step backwards. I was amazed that egosoft provided the windows beta patches in the past via galaxy so fast. Same time as steam i guess.

[ant1393]

hi ! i got ubuntu 18.10 and nvidia-415,

i can'T retrieve my new save in "./home/*myfolder*/documents/EGOSOFT/....."...

documents folder is empty.

i would like to import my saves from windows, do you found where the save is located ?

thx for help !

Eager to try it. Will buy the game as soon as the beta is out.

WOW... I thought I would have to wait a week or so to get my hands on X4... You guys ROCK! Bought at full price, THANK YOU for the Linux love! <3

.. et UN GRAND MERCé !!!!!! for the Linux version !!!!!!!!

works well here :

ubuntu 18.10 latest updates + nvidia-415.

1- game runs fine ! i'm "in-game"...

2- seems same settings than windows graphics.... (vulkan) , seems like i used MSAAX2 instead of MSAAx4 in win but not sure.

3- 1st issue : /home/*******/documents" "/Egosoft/X4/...." does not exist ; i done a manual save (not quick save), and when i relaunch game the save loads... but not the saves i imported from windows into this folder. The manual save #1 is hidden, and can't found it anywhere to replace it with my saves.
