agung@agung-K43SJ:~$ steam
Running Steam on ubuntu 15.04 64-bit

STEAM_RUNTIME is enabled automatically

Installing breakpad exception handler for appid(steam)/version(0)

libGL error: unable to load driver: nouveau_dri.so

libGL error: driver pointer missing

libGL error: failed to load driver: nouveau

libGL error: unable to load driver: swrast_dri.so

libGL error: failed to load driver: swrast

Before that, I also tried installing Steam from Terminal, but it didn't launch after having downloaded the update.

Can anyone help me finding a solution to install Steam?

Best Answer

Short version:

Start steam in the terminal using:

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

instead of just steam

Long version:

Steam can’t open nouveau_dri.so, the shared library responsible for communicating with the graphics driver. To check if the driver is OpenGL enabled run:

DISPLAY=:0 glxinfo | grep -i direct

The output should be:

direct rendering: Yes

Running steam in debug mode:

DISPLAY=:0 LIBGL_DEBUG=verbose steam

Gives us the output where the following lines gives us hint:

libGL: OpenDriver: trying /usr/lib/i386-linux-gnu/dri/nouveau_dri.so
libGL: dlopen /usr/lib/i386-linux-gnu/dri/nouveau_dri.so failed (/home/user/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /usr/lib/i386-linux-gnu/dri/nouveau_dri.so))

It seems that steam uses different version of libstdc++.so.6. Lets check which version steam uses:

ls -l ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6  

lrwxrwxrwx 1 user user 19 Jul 18  2014 /home/user/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6 -> libstdc++.so.6.0.18

So Steam loaded LibC6 with ABI version 18 where driver expects version 20.The solution is to tell OS to preload the proper LibC6 version using LD_PRELOAD variable:

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

The somewhat non-intuitive $LIB parameter gets expanded in ld.so to the right path based on the platform of the process being started (man 8 ld.so for details).

You can create script with the following content to run it instead of steam:

# Export so all child processes are affected as well
export LD_PRELOAD='/usr/$LIB/libstdc++.so.6'
export DISPLAY=:0
#export LIBGL_DEBUG=verbose

A better script could check if the global LibC6 version is newer than the one in STEAM_RUNTIME and only then LD_PRELOAD’s.

More details can be found on here. Note that I tested it on Debian and now it has been tested on Ubuntu vivid 15.04 and works fine.
