As of May 2011, all of the UCC's Windows machines run Steam. Steam presents an annoying set of problems, as it has not been engineered for a multi-user environment.

IMPORTANT: Winadmins and wheel members; don't run Steam.exe as Administrator. It will screw the permissions again.

Windows

To fix steam, you need to set Advanced Permissions (these instructions are for Windows 7):

1. Right click Steam directory
2. Choose Properties
3. Click Advanced button
4. Choose "Change Permissions..."
5. Delete any group listed except "Everyone", "gumby (UCCDOMAIN\gumby)", "wheel (UCCDOMAIN\wheel)", "winadmin (UCCDOMAIN\winadmin)" and "SYSTEM". If the list is missing any one of these groups, please add them.
6. Set groups "Everyone" and "gumby (UCCDOMAIN\gumby)" with all permissions to Allow EXCEPT "Full control", "Take ownership" and "Change permissions", which should not be ticked either way.
7. Set other groups to allow "Full Control"
8. Select option "Replace all child object permissions with inheritable permissions from this object"
9. Choose "Apply"
10. Close dialog and choose "Owner" tab
11. Ensure that owner is "SYSTEM"; if it is not, change it. Ensure you tick "Replace owner on subcontainers and objects".

Linux

Set up `/opt/steamapps`

1. Create /opt/steamapps

2. Create /opt/FixSteamPerms.sh (copy from existing, or create a script containing chmod -R 777 /opt/steamapps)

3. Add a cronjob to re-run that script every five mins or so.

Fix a user's config

(If steam isn't showing any installed games on a machine that has games installed)

1. Delete existing ~/.steam/steamapps, ~/.steam/steam/steamapps and/or ~/.local/share/Steam/steamapps

2. Create a symbolic link to /opt/steamapps in those locations
3. Start steam

How to do this;

rm -rf ~/.steam/steamapps
rm -rf ~/.steam/steam/steamapps
rm -rf ~/.local/share/Steam/steamapps
ln -s /opt/steamapps ~/.steam/steamapps
ln -s /opt/steamapps ~/.steam/steam/steamapps
ln -s /opt/steamapps ~/.local/share/Steam/steamapps

Misc Fixes

- Borderlands etc. segfaulting instantly on startup.

• - Install libnss-ldapd:i386

- Steam not starting on Mint 18 / Ubuntu 16.04

• - (TODO: Add this to the SOE config) - Start it using the following command LD_PRELOAD='/usr/$LIB/libstdc++.so.6' steam - The cause is an old version of libstdc++ in the steam libs that causes X protocol errors.
