[Linux native] Cannot launch various Source 1 games

[nixRidge]

The following games fail to launch via Steam: Black Mesa and Half-Life 2: Deathmatch.

By launching Steam through a terminal emulator, launching either of the two games produce the following output:

Note that precisely the same output is generated by Black Mesa, just swap "Half-Life 2 Deathmatch" and "hl2.sh" for "Black Mesa" and "bms.sh" respectively.

This is on Arch Linux with KDE Plasma, using the "steam" package (not steam-native-runtime). The Windows versions do launch via the Proton software bundle, but the experience is unsatisfactory compared to playing the game natively.

I have every title released by Valve, so if I should try any other game just let me know. I would also like to know how I can produce some more useful information for the developers, if possible. Thank you.

Hello @FridgeRacer, this issue is already being tracked at #5043. Closing as a duplicate.

Sorry about that, didn't search with the right terms apparently 😓
