======================

(From what I know this seems to be a proton issue but I'm still gonna report it here)

Steps for reproducing this issue:

1. Install a Linux mint iso (this might also happen in other Debian/Ubuntu based distros but I don't know) (as for mint doesn't matter which DE you use)
2. Install a game that uses proton
3. Realize that the game doesn't boot

This is not a good or supportable workaround, and is just as likely to break games as it is to fix them.

Please report an issue to https://github.com/ValveSoftware/steam-runtime/issues and provide a log, so that whatever bug you are seeing can be solved properly.

Passing around workarounds does not give us the information we need in order to solve a problem.

Hello @Twig6943, as @smcv noted this workaround is not supportable.

In general we're tracking issues with games run with Proton in the Proton issue tracker, but since you're inclined to think there's an issue with the container environment which Proton is run inside, I've transferred this issue report to the steam-runtime issue tracker for a runtime dev to ponder.

A header only Proton log generally hints that the container environment got setup, and Proton started to run, but something went wrong before the actual game got a chance to start. In addition to the details @smcv is requesting, can you undo any workarounds you tried, completely close Steam, then run steam from a terminal and check if there's any hints in the terminal spew when you tell Steam to start the game?
