OpenGL GLX context is not using direct rendering, which may cause performance problems.

Whenever I start up steam, I get this error:
"OpenGL GLX context is not using direct rendering, which may cause performance problems.
For more information visit"

System specs:
OS: Ubuntu 12.04.3 (LTS) 64-bit
Video card: Radeon HD 6850
I've installed the Linux graphics driver from the AMD website

I went to the link provided in the error message. I ran the 32-bit glxinfo and I get this:
name of display: :0
libGL: screen 0 does not appear to be DRI2 capable
libGL: OpenDriver: trying /usr/lib/i386-linux-gnu/dri/tls/
libGL: OpenDriver: trying /usr/lib/i386-linux-gnu/dri/
libGL error: failed to load driver: swrast
display: :0 screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

I'm guessing that "direct redendering: No" is one of the problems. I'm a noob so I'm not sure what to do. Any help? Thanks.

I had the same problem in debian 64 bits. You need to install some 32 bits libraries... Have a look to libgl1-mesa-dri:i386, libgl1-mesa-glx:i386 and ia32-libs

ia32-libs is no longer needed in most debian distros, as 64-bit has 32-bit multiarch already installed. (as a result, installing the 32-bit version of a package removes the 64-bit version, and cannot be installed at the same time due to multi-arch support now included in the OSes.)

Steam installed the above mentioned 32 bit packages but still says the same thing. If you have an AMD card is there something else you need to do?

this problem fixed at russian part internet. use this link

sort command list

sudo sh /usr/share/ati/
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* xorg-driver-fglrx

sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases
sudo apt-get install ia32-libs-multiarch lib32gcc1 libc6-i386

(get new driver from ....)

chmod +x
sudo sh

if driver do not install try --force key


last step

sudo aticonfig --initial -f

and now

What worked for me on openSUSE 64bit, was installing latest beta drivers from amd.
