After updating my Linux computer to the latest nvidia drivers Starsector has started crashing on launch (the launcher works but after pressing play no window for the main game is created)

I was previously using driver version 535 with no issues playing Starsector (including the same day before updating).
Looking at the standard output of Starsector the JVM seems to encounter a SIGSEV and blames

Code

C [libnvidia-glcore.so.550.54.14+0x9d50cc] _nv000glcore+0x4520fc

as the problem.

I've attached both the stdout (starsector_stdout.txt) and the associated error report (starsector_log.zip) in the hopes that they will be helpful.

Hi - sorry about the trouble! Unfortunately, this looks like a crash in the nvidia driver, so, not something I can do much about. I'd suggest rolling back the driver version, if that's an option for you.

[not_ai]

Yeah I've already rolled back to keep playing but felt that I should report it since I haven't encountered this issue (or any similar issues) on any other game/application so far.

[Alex]

I appreciate it, and that makes sense, yeah! Just, the crash clearly looks to be in the driver, and "crash bug in the driver" is definitely something that happens (and very often gets fixed in subsequent driver versions).

[not_ai]

I looked at bit closer at the error log I found a frame log that seems to suggest that the error occurs on trying to close the launcher window.
Is there a way that I can bypass the launcher and directly invoke the game to see if the launcher is the only issue?

[Alex]

If you open up data/config/settings.json in a text editor, there's a "legacyLauncher" setting - changing it to true may help with this as it'll use a different rendering method for the launcher (though you'll also lose the ability to configure screen scaling from the launcher, the legacy launcher is... old).

[not_ai]

Unfortunately that seemed to do nothing, oh well.

[not_ai]

I'm going to report this to Nvidia and hopefully learn of a fix, would you be willing to divulge what exact version of lwjgl you're using for Starsector so I can share that with the developers should they want to try and recreate the problem?

[Alex]

Good luck!

The version of LWJGL is 2.9.3.

Hmm, this looks like a mod issue? Also, this is an unrelated thread; please make a new post (in the modded reports subforum) for a new issue).

[not_ai]

Thought I'd make a note in case anyone else is experiencing a similar issue that Starsector seems to work fine using the Zink opengl driver instead of the Nvidia driver. Though it does make the game feel a little slower at the moment.
To launch starsector with zink I used this commandline.

Code

__GLX_VENDOR_LIBRARY_NAME=mesa MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink starsector

Where 'starsector' is the launch script included in the game's download

[Alex]

Thank you for sharing the info! Glad you've got a (hopefully temporary) workaround, at least.

Wow thank you dude !
I could not play starsector for a couple of months and you saved the day.

As far as I know :
- nvidia 535 -> ok
- nvidia 545 -> not ok
- nvidia 550 -> not ok

Your fix works at least with 550.

[not_ai]

Glad it also helped you.

It should also work on the 545 driver since all the opengl commands are being translated to vulkan commands then going through the GPU.
