Steam doesn't start. LibGL error [duplicate]

Solution 1:

To fix it simply open the terminal and run these commands:

rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6
rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/libgcc_s.so.1

Steam should then work properly. But make sure not to install the proprietary AMD drivers as they are very bad for the stability of the OS compared to the open source drivers. If you are getting low performance with the open source drivers, then simply upgrade the Mesa version by adding the xorg-edgers PPA

sudo add-apt-repository ppa:xorg-edgers/ppa

After that type this in order to upgrade the Mesa version:

sudo apt-get update && sudo apt-get upgrade

Then reboot and the new Mesa driver should be loaded.

Solution 2:

This got me most of the way there. I also needed to change the way I launched Steam.

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