[Semiparallel]

Enviroment Ubuntu 26.04

Problem: On Host Game at run ./X4

I think you need the no steam starting file from Egosoft for this.
I at least copied the whole folder from steam to my programming folder and applied the no steam starting file.

Also you need to deactivate the UI Safe mode in the extension menu or in the config.
In the config this must be there.

That helpt i coud start host but one Suggestion:
In x4mp_launcher.ch line #354 where it says Force the real GPU Driver radv i woud suggest removing #356 completle on a u26.04 install whit nvidia and let chose vulkan itself (i cound start because it forced Amd vulkan).

Also the host seems to miss many libarys as there is no "host game" button and client cant join.
File I/O could not find siganture file
[ALSOFT] WW cannot connect to server socker err = No such file or directory
also Jack_client_open() failed

so i coud not connect the Client.

I have made the Vulkan Renderer better and the glibc compatibility better. When you want you can test again.

version 'GLIBCXX_3.4.36' not found u26.04 supports up to 3.4.35
are you perhaps working whit a never gcc (17)?

Edit:
In CachyOS it works fine not in Ubuntu22-26 think it is because newer glibc.
Thanks for the help! Sadly i coud connect the client but nothing happed.

Edit 2:
I had to try mutlible times to get it working but it works now! Awesome!
