Control: retitle -1 steam-libs: Cyberpunk 2077 hang when starting up Control: severity -1 normal On Fri, 23 May 2025 at 19:30:29 +0200, Are Mehus wrote:
After a regular update on debian testing, it was not possible to launch Cyberpunk on Steam anymore.
Debian does not have control over the proprietary Steam client, the Proton compatibility layer that is used to run Windows games like Cyberpunk 2077, or Cyberpunk 2077 itself.
If this was triggered by an apt upgrade, please check /var/log/apt/history.log to find out which packages were upgraded between the last time it worked and now: for example this might be a regression with some newer package from the graphics stack (kernel, GPU firmware or Mesa).
You might be able to find relevant information in the systemd Journal, or in ~/.steam/steam/logs/, or by configuring Proton to record more debug logs: https://github.com/ValveSoftware/Proton
It is very unlikely that any change in steam-libs would trigger or resolve this. steam-libs only exists to ensure that some necessary packages are installed, and does not contain drivers or significant code.
