Public bug reported:

hello,
if i launch steam on ubuntu 14.04 with nvidia-prime i get some errors:

1) swrast is not exposed:

$ LIBGL_DEBUG=verbose steam
Running Steam on ubuntu 14.04 64-bit
STEAM_RUNTIME is enabled automatically
Installing breakpad exception handler for 
appid(steam)/version(1393366296_client)

directory.
libGL: Can't open configuration file /home/samu/.drirc: No such file or

libGL error: failed to load driver: swrast
[...]

2) steam complains with this error (but loads anyway)

OpenGL GLX context is not using direct rendering, which may cause performance 
problems.
For more information visit 
https://support.steampowered.com/kb_article.php?ref=9938-EYZB-7457.

steam itself works, however i'm not able to play games but i'm not sure
if this is due to previous errors or it is due to some missing 32 arch
libs since steam officially supports bumblebee and not nvidia-prime.

Let me know if you need more information

Regards
Samuele
