As you might know steam has some runtime issues when using non supported video drivers, like the open source.
The arch page explains it. And give a solution, via CLI to run steam while dodging the problem, this even works with game with their own packed trouble-making libraries.

It works well but I would like to make a script and then create a icon so I can run Steam like everyone else.
The arch page explains it but it is not very clear and I dont understand how. (the append a $@ bit sounds very obscure to me)
here are the lines...

QuoteDynamic linker
The dynamic linker (see ld.so(8)) can be used to force Steam to load the up-to-date system libraries via the LD_PRELOAD environment variable. For example:
LD_PRELOAD='/usr/$LIB/libstdc++.so.6 /usr/$LIB/libgcc_s.so.1 /usr/$LIB/libxcb.so.1 /usr/$LIB/libgpg-error.so' /usr/bin/steam
Note: The $LIB above is not a variable, but a directive to the linker to pick the appropriate architecture for the library. The single quotes are required to prevent the shell from treating $LIB as a variable.
Tip: You can put this command in a wrapper script such as /usr/local/bin/steam-preload, appending "$@" to preserve command-line arguments. This script can be referred to in a desktop file, for example through Exec=/usr/local/bin/steam-preload %U.

I am more of a linux user than a linux master so I dont really understand how to make the script...

I hope you can help.
