Steam – Issue with launching Rust from Steam (on Ubuntu 18.04)

ruststeamtechnical-issues

I recently bought and installed Rust along with Steam onto my computer (running Ubuntu 16.04 LTS and now 18.04 LTS). After downloading, I tried to run Rust first from Steam and then from the desktop icon, but to no avail. Everytime I click PLAY a window pops up saying Preparing to launch Rust..., which then closes and supposedly stops (the STOP button turns back to PLAY). I found my way to the output_log.txt file to see if there were any issues, and have pasted to content below.

eac_server.so [x64] :: OnLoad()

I assume the error is that it didn't preload libRenderer.so and libRustNative.so, but when I tried to find a solution for this I couldn't. If this is the issue, does anyone know how to fix it, or how to preload the files another way?

EDIT: I'm not trying to run a server or anything fancy, just the base game.

EDIT: I figure more information can't hurt. This is the console output when trying to run the game:

The error looks pretty straightforward.

Vulkan detection: 0
No supported renderers found, exiting

This may mean either that your Graphics card has no vulkan driver support (generally because it is too old to be supported), or simply that you don't have the necessary driver/support packages installed.

(An OpenGL renderer hasn't been supported since some time early 2019, according to a youtube video I found.)

The output of the command vulkaninfo could give more info about your vulkan support. (If it doesn't exist, install the vulkan-tools or vulkan-utils package to get it.)

If that command doesn't exit with an error, such as VK_ERROR_INITIALIZATION_FAILED, then there is a chance you can get it to work.

And probably a simple internet search will already tell you whether your graphics card should have Vulkan support.

Bear in mind that, even if you can solve the renderer issue, the game may not work. There is the possibility that the EAC Anti-Cheat will kick you out, since they have stopped their Linux support (at least for this title).

Or, since Facepunch Studios themselves have stopped supporting Linux, there is the chance that it won't work simply because the Unity engine shipped with the Linux build has issues (Perhaps they still drop updates for Linux unofficially, perhaps they don't - I have no clue.) or they might even actively kick linux clients, since no adequate cheat protection might negatively influence the playerbase as a whole (dev reddit post).
