SteamDeck needs some care again.

I'm unsure if this is an enhancement, a bug, or a support call - so I'm flagging it as a task until I have enough information to figure it out.

Fellow Kerbonaut AZZlyTheAZZome got bitten by this alert from KSPe:

KSP.log

The APPROOT and the PWD are not matching:

• APPROOT: /home/deck/.steam/steam/steamapps/common/Kerbal Space Program/
• PWD: /home/deck/.local/share/Steam/steamapps/common/Kerbal Space Program/

What's pretty weird, as this doesn't looks like a manual intervention…

See what's happening.

Apparently Steam changed the directory layout recently!

Note: If you are an Ubuntu user, the Steam installs to folder ~/.local/share/Steam.
However, new version of Steam installs to folder ~/.steam/steam/SteamApps/common.

If I confirm this, the user is launching one game, but it's using the other installation on the PWD. This is pretty bad...

User reported that running from the SDCard fixed the problem.

So, apparently, on Steam Deck the "canonical" files are going into /home/deck/.steam/steam/steamapps/common/ and the users files into /home/deck/.local/share/Steam/steamapps/common/

I'm trying to find some documentation about the matter.

To think is a very healthy habit, you now? I think I should try doing it more frequently.

Steam Deck runs over SteamOS, and there's a fork to run it on PCs.

I need to build a Steam Machine on some old hardware I have laying around, so I can properly validate Deck support without the need to wait something happening on a user's machine - and being reported (as most user's don't report problems, just quit).

I own a Steam Deck now. More than due time to have this solved!
