Has this game ever worked on this machine? Or never yet?

Please attach this log file here:
~/.config/unity3d/Colossal Order/Cities_ Skylines/player.log

 

[dkleszyk]

Andrew,

Yes, the game ran as of a few weeks ago. I'm assuming some combination of software and/or driver updates broke it.

The player.log file does not appear to be written to.

 

[AndrewT]

That implies the launcher is not even starting the game, as writing that log is the first thing it does.

In a terminal command box change directly to /home/dkleszyk/.local/share/Steam/steamapps/common/Cities_Skylines/ and run ./cities manually. the game won't start that way (it needs to be run from Steam) but does it at least make that player.log file? Any significant errors shown there?

 

[dkleszyk]

The same behavior occurs without the steam client running. The player.log file is not written.

The backtrace (attached) looks similar.

 

[AndrewT]

I see nothing in there to point to even the general area of the problem, I'm sorry. This may need Linux diagnostic help to pin down, my Linux knowledge is way too rusty to help much absent clear indications in the log.

Ubuntu 23.04 (64 bit)

Did this first happen just after you went to this version? Or you've run okay under that?

If the latter, did this first happen after some system update?

 

[dkleszyk]

Trying to debug the issue, I have found that the game will occasionally launch successfully. Maybe 1 in 10 times or so. I have not been able to determine exactly the launch vs crash conditions though. Maybe there is some race condition in the launcher or one of its libraries.

[dkleszyk]

Yes, this first happened after upgrading to 23.04.

I've noticed that the game will eventually launch if I keep trying.

 

[AndrewT]

I was going to update to 23.04 to test for you but I see it's only an Interim release so far, not LTS.

I don't suppose you'd consider going back to 22.04 LTS?
