 Posted: Tue Mar 05, 2024 1:06 pm Post subject: Shared Steam directory for different users |
 |
|
Hi there,
I built a gaming computer for my son. And of course I want to be able to play with this computer too.
So first I installed Lutris and specified as base directory: /opt/games
To be able to use this directory with different users:
| Code: |
mkdir /opt/games
groupadd games
gpasswd -a userA games
gpasswd -a userB games
chown root:games /opt/games
chmod 2775 /opt/games |
The last line should grant the access to every user in the games group and inherit the group rights.
But unfortunately that doesn't work.
Steam installs the Steam contents into ~/.local/share/Steam
If I move this directory to /opt/games and fix the permissions and ownership, steam complains: libsteamui.so not found., although I've changed the install directory in the Steam UI. And after moving the Steam directory. Steam doesn't start anymore. Btw. Lutris doesn't even find Steam.
The next step was only to move the steamapps directory to /opt/games and keep the other Steam stuff in the User Home directory. But after changing the ownerships any installed game (e.g. Stumble Guys) starts and starts over but crashes after 2 seconds.
My goal:
- 2 user accounts
- 2 steam accounts
- 1 shared directory for the game installation (in order to not to install every game twice)
- Save games stored in the User directory
Is that possible somehow? |

Hi,
Might said something stupid here, but are you sure Lutris can access /opt ?
What are the permissions, user and group owner for /opt and /opt/game aswell ?
I sometimes put things in /opt too, IIRC I have this:
| Quote: |
kgdrenefort@Mephistopheles /etc/portage $ ls -la /
(… … …)
drwxr-xr-x 11 kgdrenefort kgdrenefort 159 14 févr. 15:13 opt |
| Quote: | kgdrenefort@Mephistopheles /etc/portage $ ls -la /opt
total 12
drwxr-xr-x 11 kgdrenefort kgdrenefort 159 14 févr. 15:13 .

If I were you, I would not give root:games, maybe games:games and set your both users on the same groups (games) and be sure groups it's 'rwx' to allow full access. So far as I know, this directory can safely be authorized to whom ever you want. But I don't see the point to make the main user root. Can be wrong here. Give it a try.
Hope this is useful.

root isn't the point here. It will be overwritten by every user, who writes something in this directory. As you mentioned the group games with permssions rwxrws--- should be the relevant part. The set-gid bit should be responsible to inherit the group rights.
And lutris is started with user permissions. So it can write to /opt/games.
It should be something inside Steam, which denies the usage of directories shared by local users.
On the other hand:
You can use 2 Steam accounts parallel within 1 user account. Means, I can start the steam runtime and switch the steam users inside Steam. But this feature doesn't respect the users of the computer of course. |

Kind of: "Save games stored in the User directory" are taken care of by steam, game saves will be separate to each "steam account", even with the same user.
"1 shared directory for the game installation" doesn't work 100% with 2 system user accounts, you set it up by just installing steam locally for each user, then pointing to /opt/games/SteamLibrary as the default game installation destination. The problem is that during updates steam will create files with user:usergrp ownership, then upon switching system user you'll get permission errors.
There are two ways round this:- Wrap steam, so on start-up permissions for /opt/games/SteamLibrary/ are updated to g+rw and :games
- Create a 'gamer' user that both system users run steam as, that way the permissions will always be 'correct'
Personally, I wrapped steam so the lad didn't mess with my own "steam settings per game", and the only time I had to install things twice was if we used multiseat and were playing the same game at the same time. |
