I downloaded steam and tried opening it. The icon flashed a few times but nothing happened.
I ran it with the terminal but it gave the following error message:
Running Steam on ubuntu 16.04 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
Any idea what's wrong?
