This question is an exact duplicate of:
I'm trying to run and install Steam on Kali Linux 64bits and I get libGL errors like :
Running Steam on kali kali-rolling 64-bit STEAM_RUNTIME is enabled automatically Installing breakpad exception handler for appid(steam)/version(0) libGL error: unable to load driver: r600_dri.so libGL error: driver pointer missing libGL error: failed to load driver: r600 libGL error: unable to load driver: swrast_dri.so libGL error: failed to load driver: swrast
It seem that libGL can't find my drivers (I have ATI Radeon). I found multiple solution but no one worked fine.
