Linux Port – Feedback, Known Issues, and FAQ

*wrong thread

 

Currently experiencing the Nvidia window resolution bug; is there any way to temp perma fix this so that I dont have to open settings files everytime I launch the game? (which sometimes ends up being multiple times a session)

Another small issue I have experienced is the mouse wont stay focused on the game such as when moving the camera in freecam (x11 window system used with KDE desktop environment Ubuntu 24.04 and everything up to date); didnt occur in 0.36.

Aside from all that things work smooth as possible great update.

 

Hey, any news about the G27's DPAD?

 

Best devs ever! thank you!

 

I must still be doing something wrong - I cannot get the Linux version to start on steam deck and actually do anything.

right now I get just a black screen where I can see the HUD only. I can hear the vehicle if I press the trigger but I don’t see the vehicle.

also, the game appears to be running in x11 and any attempt to start it in Wayland doesn’t seem to work at all.

Once I launch it once, subsequent launches fail if I modify any graphics settings with a fatal lua error in dof.lua attempt to perform arithmetic on local ‘blurcurvenear’

 

looks like game tries to run with mesa driver instead amdgpu
whut happens if u start game from command line by adding "DRI_PRIME=1" or "env DRI_PRIME=1" before beamng command?

 

I can't tell if that's making any difference since I am still getting the lua crash which causes the game to no longer start after the first run. I can tell you that it's still using radv from mesa.

Here's what I get when I try to launch wayland from gamescope

Code:

u tried disbaling depth of field option in graphics?

since u wrote ur game not start and i assume u cant get to options
do edit line
from

Code:

  "PostFXDOFGeneralEnabled":true,

to

Code:

  "PostFXDOFGeneralEnabled":false,

in file

Code:

/home/USER_NAME/.local/share/BeamNG/BeamNG.drive/current/settings/settings.json

and see if it helps for u
--- Post updated ---

also
u sure u aint using modded game? coz this particular error means there is an error in game file
in case u use mods like reshade or some other graphics mod please disable it for a try

 

No mods, same issue though with DOF disabled. I am trying to completely uninstall the game and reinstall it though now.

 

if this the way of fix for u then make a backup of game files after fresh reinstall so u can restore fixed version each time after first run that breaks game for ya

but for real
please try replacing contents of

Code:

/home/USER_NAME/.local/share/BeamNG/BeamNG.drive/current/settings/postfxsettings.postfx

to

Code:

especcialy make caution to line

Code:

    "BlurCurveNear":"20.000",

since error u got means you have wrong value there
and if it fixes game for ya make the whole file read-only after fix

 

a fully fresh installation worked. It still is running in x11 mode on SteamDeck (which I thought ran in wayland when in gaming mode/gamescope) but otherwise appears to be fine.

 

I'm on linux mint, using dual monitors, and run the game in borderless mode. My main is 3440x1440, and second is normal 1080. Sometimes whilst modding (normally after I cause one of many lua errors), the game crashes on ctrl+L, then will crash on loading. I've only had this issue since the 0.37 update.

I bring up the monitor thing, because in the log, during launch, it gets up to an area, talking about "Sanitizing display" (I forgot to take of copy of the log before fixing it) and it mentions my resolution. I can't remember the exact place it froze, and I can't seem to replicate it again, currently.

I fix the issue by having my mouse on my 1080p screen, which launches the application on that screen, then I switch it to my main screen. This leads me to believe that it's a resolution based issue. If you need more info, I'll try harder to remember to take the log after the crash, and during boot crashes.

oh wait, I loaded in, and now I have this issue. I'll try to troubleshoot it, like normal, but thought I'd share it. I can't move the camera with this happening, and the graphics are terrible, but the rest of the game seems fine.


Changing display mode did nothing, but rebooting the game fixed it, no issues now.

 

Game freezes every hour. Have to relaunch game every time

 

since the new update, pressing ctrl+L unpauses the game. Not sure if this is normal, but for my niche circumstances, it can get it the way

 

Unfortunately, i still getting same freezes on last hotfix.
