Finally, I can run Steam on Ubuntu 18.04

I was struggling to run Steam on my Ubuntu 18.04. The Steam installation went very well and no sign of any errors. But every time I tried to run Steam, nothing happened. When I use Terminal to run it, I got some lines of errors such as:

Repairing installation, linking /home/alquimista/.steam/steam to /home/alquimista/.local/share/Steam
Running Steam on manjarolinux 17.0 64-bit
STEAM_RUNTIME is enabled automatically
Installing breakpad exception handler for appid(steam)/version(0)
/home/alquimista/.local/share/Steam/ubuntu12_32/steam: symbol lookup error: /usr/lib32/libxcb-dri3.so.0: undefined symbol: xcb_send_request_with_fds
/home/alquimista/.local/share/Steam/steam.sh: linha 444: sem correspondência: ssfn*

Well, that’s no good at all. I was expecting a smooth installation process but in fact, I got those errors. 

How to Fix it?

Now I can smile because, with a single command, those errors were fixed. And now, I can run my Steam on Ubuntu 18.04 smoothly. If you encounter the same error after you install Steam, use this command to fix it.

LIBGL_DRI3_DISABLE=1 steam

That’s all. The command will do the magic.
