[12.3 64bit] Steam will not start

Installed steam with the one-click install and it started and updated but after that when I start steam it pops up for a second then goes away. I also started it through the terminal and got this:

cole@linux-1woq:~> steam

I’ve tried starting it with STEAM_RUNTIME=0 and I get the same result. Not sure if i just didn’t install it correctly or what but I don’t know what to do.

System Specs:

i5-3570k
8gb 1600Mhz
7870Ghz edition
fglrx

Video card and driver?? Most of those seem to be video errors

Listed in the OP but its an amd 7870Ghz edition and all i know about the drivers are that they are the fglrx proprietary ones.

sorry did not see that but that should be on so I don’t know. Just noticed that most of the errors were X related and thus maybe a video issue

Please install the package “Mesa-demo-x” and post the output of:

glxinfo | grep render

Does the OP maybe have one of these configs with a GPU on the i5, plus a discrete AMD/ATI?

I ended up just starting on a fresh install and compiled the drivers myself and now I don’t have this error.
