Hello,

I'm trying to run Steam on my setup but it is not nearly usable. I'm not using Ubuntu, Debian or any other famous distribution. After the client starts the UI takes like 5min. to actually start doing something after me interacting with it, like clicking on Library. When I start it from a terminal the following appears on it:

I've tried setting STEAM_RUNTIME manually to 1 when running it but that does not help, setting it to 0 it complains about missing libraries but even after installing the required software (in my case gtk+ and pulseaudio) the result is the same. I have also tried running it with nouveau and nvidia 337.25 - no change. I have removed the local steam files (~/.local/share/Steam) - no joy. I have tried setting LD_LIBRARY_PATH to the runtime directory that holds some extra libraries (~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/) as env. variable - same thing. I really have no idea what to do next. Any help is appreciated.
