BATTLETECH - Black screen w/ cursor at startup

BeStillAsBright · Apr 17, 2020

One line summary of your issue
Black screen w/ cursor at startup

What platform are you running the game on?

Steam

What operating system do you use?
Linux - Ubuntu 20.04
Which version of the game are you running?
1.9.1
What DLC do you have installed?

Please explain your issue is in as much detail as possible.
The game launches from Steam to a black screen with the custom white cursor. Nothing seems to happen and eventually I get a system dialogue to kill the program. I've tried dismissing it a couple of times, with no results.

I tried the trick of deleting (or well, moving) libc.so.6 from the game directory but that did not help.

Checking Player.log, it appears that there's an issue loading shaders. I have the latest Nvidia driver for my rtx2060 (440.82) installed, so I'm not sure whether that's it or not

Note: I realize that Ubuntu 20.04 is technically still in beta but it should be pretty much frozen and releases in like 4 days or so (I just got this computer and didn't want to install 19.10 and then do a dist-upgrade like 10 days later).
Have you tried verifying your files?
Yes

Steps to reproduce the issue
0. Install on Steam
1. Run from Steam

Attach DxDiag (PC), System Info log (Mac), or run sudo lshw -html > specs.html and uploaded specs.html (Linux)

AndrewT can correct me if I'm wrong, but it looks like.. it's trying to use the vmware llvmpipe for rendering the game, and that most likely doesn't support everything the game requires to run.

Desktop is 1920 x 1080 @ 77 Hz
Initialize engine version: 2018.4.2f1 (d6fb3630ea75)
GfxDevice: creating device client; threaded=1
Renderer: llvmpipe (LLVM 9.0.1, 256 bits)
Vendor: VMware, Inc.
Version: 3.3 (Core Profile) Mesa 20.0.4

As an example of what the header of the player.log should read like:

Desktop is 2560 x 1440 @ 60 Hz
Initialize engine version: 2018.4.2f1 (d6fb3630ea75)
GfxDevice: creating device client; threaded=1

Yeah, no way will this game run in a VM.

What is your native OS, why not run it in that?

BeStillAsBright · Apr 17, 2020

My native OS is Ubuntu 20.04, I have no idea why it's trying to run it through LLVM.

Okay, I think I got it using the nvidia drivers, however it still won't run with the same issue occurring. Here's the top of an updated Player.log file. I couldn't attach the full log because it's too big and I'm not allowed to post links yet, but hopefully it's enough to give you guys an idea.

edit: I know that 440.82 is the latest driver version released last week but Ubuntu's packaging doesn't have it updated yet. I could try a manual install if you think it'd help.

edit 2: I did upgrade graphics drivers via Nvidia's command line installer, though it unfortunately did not help.

I haven't tried 20.04 as yet, but those look pretty clearly like graphics-related issues. Are you on X.org or Wayland? If th elatter try the former (it that's still possible!).

You could also try this: In your Steam Library right-click on this game and choose Properties. Click on Set Launch Options, and paste this in there:
-force-glcore

Adding -force-glcore seemed to do it, I was able to successfully launch and start a test skirmish. Thanks so much!
