[SPZ2-6232] [1.0-?] [Linux] Instant crash on startup after removing monitor last played | Shapez 2 | Page 1

I was using a temporary second monitor and placed the game there. Upon removing the monitor, the game immediately crashed. Attempting to start the game after that starts and then crashes before it gets past the black screen. I have not tested whether re-plugging the second monitor fixes this as I don't have the monitor with me.

I don't know what the game version is because the game doesn't open, but it is latest as of time of posting on steam, without any betas or other branches.

tried it, still doesn't work

#

it did request a 1280x720 in the logs so that's good at least but the game didn't open

Now that it is attempting the smaller resolution maybe try the following launch option: --safe-mode

solar plaza May 5, 2026, 2:08 PM

#

no change

#

i just put --safe-mode in the launch options in steam and relaunched it

#

is there anything that identifies safe mode being active

#

the logs don't seem to mention it

1. [SPZ2-6266] — ✨ 85% similar

[Linux] Title always exits shortly after starting it
To Do • Priority: High • Fix: None • Game: 1.0.3-rc3

On Linux (Ubuntu and Arch), shapez 2 crashes shortly after launching, though the issue is not 100% reproducible. A fatal runtime error occurs in the Mono runtime or a native library. The crash can be worked around by using a non-native resolution or by manually creating a display.json file in the local folder with a specific resolution and windowed mode. The expected behavior is that shapez 2 starts successfully every time without requiring manual configuration changes.

[Linux] The title will end straight after starting a few times before starting properly
To Do • Priority: Medium • Fix: None • Game: 1.0.3-rc3

On Linux (Ubuntu, Arch), shapez 2 crashes immediately after launching multiple times before eventually starting properly. The issue is triggered by a fatal runtime error in the Mono runtime or one of its native libraries, with native fault reporting also failing, which leaves some diagnostic information unavailable. The expected behavior is that shapez 2 should start properly on the first launch attempt.

Exception: No displays found
Done • Priority: Medium • Fix: Future • Game: 0.0.7 • Resolution: Done

The game crashes with an "Exception: No displays found" error when the system fails to detect any monitors during Graphics / Display / Visuals settings initialization. This occurs during screen configuration when Unity does not provide display information, affecting a few users. The crash prevents the game from starting or applying display settings properly. A restart sometimes fixes the issue for some users. A workaround was implemented to assume a default Full HD resolution and use the prim...

--safe-mode launch option goes to native resolution because of playerprefs settings on starting the title
To Do • Priority: High • Fix: None • Game: 1.0.3-rc3

The --safe-mode launch option in shapez 2 fails to enforce 1280x720 resolution on startup, instead defaulting to native resolution due to playerprefs settings being applied first. This is particularly problematic on Linux, where launching at native resolution frequently causes crashes. To reproduce, the user must clear registry and display settings before launching with --safe-mode. The expected behavior is that --safe-mode should maintain 1280x720 resolution from startup through reaching the...

Shapez 2 can crash when switching graphics settings while using Linux.
To Do • Priority: Critical • Fix: None • Game: 0.1.1

shapez 2 can crash or become unstable on Linux when changing and applying graphics settings such as resolution and window mode. This occurs when users navigate to Settings > Graphics and apply changes. Additionally, some users experience crashes at startup, potentially due to the application attempting to apply outdated graphics settings from a previous version before the settings refactor in rc1. The expected behavior is that the game remains functional and stable after applying graphics cha...

Crash on startup
Done • Priority: Medium • Fix: Version 0.0.9 • Game: 24.2.2 • Resolution: Won't Fix

shapez 2 crashes on startup with a SIGSEGV error when running natively on Linux, likely triggered by recent OS package updates (such as mesa, mutter, vulkan-loader, or xwayland). The game was previously working but newer package versions broke compatibility. Running under Proton appears to work as a workaround, though sound issues were also reported. The crash occurs in native code before the menu is displayed. This is not something the development team can fix on their end, so using Proton i...

What about proton?

solar plaza May 5, 2026, 2:20 PM

#

just checked, game does work under proton

#

although it won't fullscreen properly and the background factory is shifted off the screen

#

#

but that's probably just a proton thing

whole pilot May 5, 2026, 2:45 PM

solar plaza

The detail you see in the main menu indicates you are most likely in safe mode.

#

Could try changing it to windowed but a lower resolution than full screen. then Exit the game. Restart (might be ok to remove safe mode if using proton)

solar plaza May 5, 2026, 2:48 PM

oh yeah no those totally worked
