Ubuntu 12.10 x64 was working...but not anymore. Why?

[abundantmind]

I completely understand that the beta is intended for 12.04 users, but I was playing Half Life after I purchased it for several days...when it just stopped working. Very frustrating...

Possible Causes...

1. I was fiddling with the Big Picture option and probably checked that as the default view (cuz it's cool!) for when I open the app.

2. Steam updated itself...and broke itself.

3. ???

Now when I click on the Steam Icon it appears in the tray on the left for a few seconds...then it just dies.

Any suggestions would be appreciated, including possible command line instructions to uninstall and re-install from scratch.

Run steam from terminal and see what is the error.

Here's the tail end of the output...

If I pipe the terminal output into steam.out file, here's the contents...

If I Ctrl-C out of the terminal window, I get these results...

Try:
STEAM_RUNTIME=0 steam
in terminal and wait for steam to update. After that it should be fixed...

[abundantmind]

Perfect. Thanks a bunch.

I'm having a similar issue on debian 64bit but that command doesn't fix it for me

Edit: hmm may have solved the issue for the moment, unfortunately I think it deleted my games or maybe uninstalling steam and reinstalling did either way here's what fixed it: rm -Rf ~/.steam/steam/appcache as suggested by http://askubuntu.com/questions/345120/why-doesnt-steam-start

PS: or rather it ignored the installed files in ~/.local/share/Steam/SteamApps/ and I'm not sure how to make it see that folder again got it

Or not... close steam open it again doesn't start >_<
