Reply to Private Server will not start at all, either from desktop launcher or through Steam on Invalid Date

rysade — Invalid Date

Starting the Private Server hangs when the backend module loads, never proceeding past it. It seems to think that Steam is not running, but it is.

Excerpt from backend.log:

Loading mods in 'mods'
Connecting to storage

Connecting to local Steam client failed: Steam is not running
Using Steam Web API authentication instead

It continues on that way for quite a while and never fails out.

Steam is starting differently from how it normally does, using the following line:

LD_PRELOAD='/usr/$LIB/libstdc++.so.6' DISPLAY=:0 /usr/bin/steam

The reason for that is Steam would not start at all without it, though I don't know why.
